The standard knot 400 has four main chords 410, where the main chords 410 include a rod 411, a male tenon 412 and a female tenon 413, and the male tenon 412 and the female tenon 413 are respectively disposed at two ends of the rod 411.

In this embodiment, the fixture includes a base 100, a first clamping and positioning module 200, and a second clamping and positioning module 300. The base body 100 is provided with a first positioning end face 101 and a second positioning end face 102 along a first direction X, the base body 100 is further provided with a clamping cavity 103 penetrating through the first positioning end face 101 and the second positioning end face 102, and the clamping cavity 103 is used for accommodating the standard joint 400. In this embodiment, the cross-sectional shape of the clamping cavity 103 is adapted to the cross-sectional shape of the standard joint 400 in the width direction, so that the standard joint 400 can smoothly enter and exit the clamping cavity 103.

Further, the distance from the first positioning end face 101 to the second positioning end face 102 is smaller than or equal to the length of the rod 411, so that two ends of the standard joint 400 can be exposed outside the base body 100 after entering the clamping cavity 103, and milling and boring of the male tenon 412 and the female tenon 413 are facilitated.

The first clamping and positioning module 200 is disposed on the first positioning end surface 101 and is used for supporting the outer cylindrical surface of the tenon 412; the second clamping and positioning module 300 is disposed on the second positioning end surface 102 and is used for supporting the outer cylindrical surface of the female tenon 413.

The tool fixture provided in this embodiment pushes the standard knot 400 into the clamping cavity 103 of the base body 100 from the first positioning end surface 101 or the second positioning end surface 102, then abuts against the outer cylindrical surface of the male tenon 412 of the main chord 410 through the first clamping positioning module 200 located on the first positioning end surface 101 of the base body 100, abuts against the outer cylindrical surface of the female tenon 413 of the main chord 410 through the second clamping positioning module 300 located on the second positioning end surface 102 of the base body 100, and thus the clamping and positioning of the standard knot 400 are realized.

Since the distance from the first positioning end surface 101 to the second positioning end surface 102 of the base 100 along the first direction X is less than or equal to the length of the rod body 411 of the standard knot 400, after the standard knot 400 is received, the male tenon 412 and the female tenon 413 of the main chord 410 can be exposed outside the base 100, so that the standard knot 400 can be clamped and fixed, and meanwhile, the male tenon 412 and the female tenon 413 can be processed conveniently.

Further, the tool fixture provided in this embodiment can support the outer cylindrical surface of the male tenon 412 through the first clamping and positioning module 200, and the second clamping and positioning module 300 can support the outer cylindrical surface of the female tenon 413, so that the length of the cantilever section from the clamping position to the processing position can be effectively shortened, the clamping is more stable, the vibration generated during processing is effectively prevented, and the processing precision is improved.

Referring to fig. 3, 4, 5 and 12, the third clamping module 250 includes a third mounting base 251, a third fixed pressing block 252 and a second movable pressing block assembly 253. The third mounting seats 251 are disposed at the corresponding corner portions 140, and in particular, the third mounting seats 251 may be detachably connected to the base 100 by welding or screws. The third mounting seat 251 is an "L" -shaped right-angle block, whereby the third mounting seat 251 includes a fifth right-angle portion 2510 and a sixth right-angle portion 2511 that are perpendicular to each other, a fourth slot (not shown) for mounting the third fixed press block 252 is provided on the fifth right-angle portion 2510, and a fifth slot (not shown) for mounting the second movable press block assembly 253 is provided on the sixth right-angle portion 2511, and the fifth slot penetrates the sixth right-angle portion 2511 in the second direction Y.

The third fixed pressing block 252 is disposed in the fourth slot of the fifth right angle portion 2510, and the abutting side of the third fixed pressing block 252 faces the clamping cavity 103 along the third direction Z. Alternatively, the third fixing pressing block 252 may be detachably coupled to the fifth right angle portion 2510 using welding or screws.

The second movable pressing block assembly 253 is arranged in the fifth groove of the sixth right-angle portion 2511 in a telescopic and adjustable mode along the second direction Y, and the abutting side of the second movable pressing block assembly 253 faces the clamping cavity 103 along the second direction Y. In the present embodiment, the structural scheme of the second movable block assembly 253 is identical to that of the first movable block assembly 233 described above, and thus, the above description of the structural scheme of the first movable block assembly 233 (refer to fig. 6) is also applicable to the second movable block assembly 253, which are different in arrangement orientation. Therefore, the structure of the second movable block assembly 253 will not be described in detail in this embodiment.

Referring to fig. 4 and fig. 5, it should be noted that, when the third clamping module 250 is disposed on the first positioning end surface 101, the third fixed pressing block 252 and the second movable pressing block 253 are used to abut against the outer cylindrical surface of the male tenon 412; when the third clamping module 250 is disposed on the second positioning end surface 102, the third fixed pressing block 252 and the second movable pressing block assembly 253 are used for abutting against the outer cylindrical surface of the female tenon 413.

Referring to fig. 3, 4, 5 and 13, the fourth clamping module 260 includes a fourth mounting seat 261 and two third movable pressing assemblies 262. The fourth mounting seat 261 is disposed at the corresponding corner portion 140, and specifically, the fourth mounting seat 261 may be detachably connected with the base 100 by welding or screws. The fourth mounting seat 261 is an L-shaped right angle block, and thus the fourth mounting seat 261 includes a seventh right angle portion 2610 and an eighth right angle portion 2611 that are perpendicular to each other, and sixth slots (not shown) for mounting the third movable press block assembly 262 are provided in each of the seventh right angle portion 2610 and the eighth right angle portion 2611. The sixth slot on the seventh right angle portion 2610 is configured to pass through along the second direction Y; the sixth groove in the eighth right angle portion 2611 extends in the third direction Z.

The two third movable press block assemblies 262 are telescopically and adjustably disposed in the sixth slots of the corresponding seventh right angle portion 2610 and eighth right angle portion 2611, respectively. The abutting side of the third movable pressing block assembly 262 disposed at the seventh right angle portion 2610 faces the clamping cavity 103 along the second direction Y, and the abutting side of the third movable pressing block assembly 262 disposed at the eighth right angle portion 2611 faces the clamping cavity 103 along the third direction Z.

In the present embodiment, the structural scheme of the two third movable briquetting assemblies 262 is identical to that of the first movable briquetting assemblies 233 described above, and thus the above description of the structural scheme of the first movable briquetting assemblies 233 (refer to fig. 6) is equally applicable to the two third movable briquetting assemblies 262, which are different in arrangement orientation. Therefore, the structure of the third movable block assembly 262 will not be described in detail in this embodiment.

Referring to fig. 4 and fig. 5, it should be noted that, when the fourth clamping module 260 is disposed on the first positioning end surface 101, two third movable pressing blocks 262 are used to abut against the outer cylindrical surface of the male tenon 412; when the fourth clamping module 260 is disposed on the second positioning end surface 102, the two third movable pressing block assemblies 262 are used for abutting against the outer cylindrical surface of the female tenon 413.

Referring to fig. 2, 4 and 5, in the present embodiment, when the working fixture clamps the standard joint 400, the first plane M1 and the second plane M2 are located in the third direction Z, and the third direction Z is a vertical direction, and the first plane M1 is located below the second plane M2. Considering that the standard joint 400 will be attached to the first plane M1 under the action of its own weight after being clamped, in this embodiment, the first positioning module 210 is disposed on the first clamping module 230 on the first positioning end face 101, and the second positioning module 310 is disposed on the first clamping module 230 on the second positioning end face 102.

The first positioning module 210 is used for being abutted against a first reference surface of the male tenon 412, and the second positioning module 310 is used for being abutted against a second reference surface of the female tenon 413, so that a clamping effect on the standard joint 400 along the first direction X can be formed through the first positioning module 210 and the second positioning module 310, and therefore limiting of the marking joint in the first direction X is achieved.

It should be further noted that the first reference surface and the second reference surface are both pre-machined surfaces, and the first reference surface may be an end surface or a shoulder surface of the male tenon 412, and the second reference surface may be an end surface of the female tenon 413.

Referring to fig. 10, specifically, the first positioning module 210 and the second positioning module 310 each include a positioning shaft 211 and a positioning plate 212. The positioning shaft 211 is detachably disposed on the corresponding first clamping module 230, and may specifically be disposed on the first mounting seat 231 or the first fixing pressing block 232. The positioning plate 212 is detachably disposed at an end of the positioning shaft 211 away from the base 100. The detachable mode can be threaded connection or clamping connection. It can be appreciated that the side of the positioning plate 212 of the first positioning module 210 facing the base 100 is used for abutting against a corresponding first reference surface, and the side of the positioning plate 212 of the second positioning module 310 facing the base 100 is used for abutting against a corresponding second reference surface.

Alternatively, the positioning plate 212 has a disk shape, and thus, the positioning plate 212 has an outer cylindrical surface. Therefore, when the adjustment marking section moves in the second direction Y and the third direction Z, the outer cylindrical surface of the positioning plate 212 is in line contact with the surface of the standard section 400, so that the surface of the standard section 400 can be effectively prevented from being scratched.

It should be noted that, the length of the positioning shaft 211 in the first positioning module 210 may be selected according to the distance between the first reference surface and the first clamping module 230 during the clamping process of the standard joint 400. When the first reference surface is a shoulder surface of the tenon 412, the positioning shaft 211 may be omitted directly when the positioning plate 212 is directly mounted on the first mounting seat 231 or the first fixing pressing block 232 to complete positioning (refer to fig. 6). Similarly, the length of the positioning shaft 211 in the second positioning module 310 may be selected according to the distance between the first reference surface and the first clamping module 230 during the clamping process of the standard knot 400. Thus, in the present embodiment, the length of the positioning shaft 211 is not particularly limited.

Referring to fig. 1 to 13, a method for clamping a standard section 400 of a fixture according to the present embodiment is as follows:

it should be noted that, in the blank piece of the standard joint 400 provided in this embodiment, the shoulder surface of the male tenon 412 is used as a first reference surface, and the end surface of the female tenon 413 is used as a second reference surface. Thus, when feeding is performed:

in a first step, the second positioning module 310 located on the first clamping module 230 of the second positioning end surface 102 is removed.

In the second step, the male tenon 412 of the standard joint 400 is oriented towards the second positioning end surface 102, and then the standard joint 400 is pushed into the clamping cavity 103 from the second positioning end surface 102.

Third, when the standard joint 400 completely enters the clamping cavity 103 and the first reference surface of the tenon 412 abuts against the positioning plate 212 of the first positioning module 210 located on the first positioning end face 101, positioning of the standard joint 400 along the first direction X is achieved.

Fourth, the wrench tool is used to adjust the first clamping module 230 and the fourth clamping module 260 located on the first positioning end surface 101 and the second positioning end surface 102, specifically to drive the first movable press block assembly 233 and the corresponding third movable press block assembly 262 to extend along the third direction Z, so as to push the standard joint 400 to move upwards along the third direction Z, so that the standard joint 400 contacts the abutting sides of the second fixed press block 242 located in the second clamping module 240 of the second plane M2 and the third fixed press block 252 located in the third clamping module 250 (at this time, the adjusting screw 2332 in the first movable press block assembly 233 and the third movable press block assembly 262 is not fully screwed).

Fifth, the second clamping module 240 and the fourth clamping module 260 are then adjusted by using a wrench tool, specifically, the second movable pressing block assembly 253 and the corresponding third movable pressing block assembly 262 are driven to extend along the second direction Y, so as to push the standard knot 400 to move along the second direction Y towards a side close to the first clamping module 230 and the third clamping module 250, so that the standard knot 400 is in contact with the abutting side of the first movable pressing block assembly 233 in the first clamping module 230 and the second fixed pressing block 242 in the third positioning module (at this time, the adjusting screw 2332 in the second movable pressing block assembly 253 and the third movable pressing block assembly 262 are not fully screwed).

In the sixth step, the second positioning module 310 detached in the first step is installed so that the positioning plate 212 in the second positioning module 310 abuts against the end face of the female tenon 413.

Seventh, the adjusting screws 2332 in the first clamping module 230, the third clamping module 250 and the fourth clamping module 260 are sequentially screwed, so that the positioning and clamping operation of the standard joint 400 is completed.

It should be noted that, the adjusting screws 2332 in the first clamping module 230, the third clamping module 250 and the fourth clamping module 260 are screwed down twice, because the spatial positions of the standard segments 400 in the circumferential direction in the clamping cavity 103 need to be precisely adjusted, so that difficulty in screwing down the adjusting screws 2332 on one side and the adjusting screws 2332 on the other side after a single screwing down is avoided, and meanwhile, the surface of the main chord 410 is prevented from being scratched.

Furthermore, the embodiment also provides a processing device, which comprises the numerical control machine tool and the clamping fixture provided by the embodiment, wherein the clamping fixture is arranged on the base of the numerical control machine tool. The numerical control machine tool can perform at least one of drilling, boring and milling operations on the male tenon 412 and/or the female tenon 413 of the clamped standard section 400.
