Technical Field
The utility model relates to a fixture for machining, in particular to a fixture for turning a motor base.
Technical Field
At present, in small batch processing of motor bases, the same vertical lathe processing equipment is required to process products of a plurality of specifications, wherein the products have the same type but different lengths, similar products of different types, products of different series with the same specification, and products of different specifications have similar external dimensions, but have certain differences in radial dimensions and axial lengths, and particularly, the products of the same specification but different series also have the differences in external dimensions. Therefore, the tool clamp for turning the machine base is poor in universality.
Disclosure of Invention
The utility model provides a fixture for machine base turning, which has good universality and improves the machining efficiency of a motor base on the premise of ensuring the machining precision.
In order to achieve the above purpose, the present utility model adopts the following technical scheme: a frock clamp that frame lathe work was used, its characterized in that: the upper port of the fixed ring is a step hole, the positioning ring is arranged at the step hole, the positioning ring and the lower end spigot of the motor base vertically arranged form radial positioning and axial supporting matching, the vertically arranged lifting rod is arranged on the workbench, the upper end of the lifting rod is hinged with one end of the swing arm, the hinge shaft core is positioned in the plumb direction, and the other end of the swing arm is detachably connected with the pressing plate.
The fixed ring provides a basic reference, namely, the step holes at the upper end of the fixed ring are used for replacing positioning rings with different specifications according to requirements, the pipe orifice at the upper end of the positioning ring can be adapted to the spigot of different motor bases, so that the motor bases are positioned in a vertical mode, the other end, namely, the free end, of the swing arm can be used for replacing the pressing plate to ensure that the pressing plate can reach the position above the lug on the upper end of the motor base when the swing arm is rotated, and the pressing plate is driven to be pressed onto the corresponding lug when the swing arm descends along with the lifting rod, so that the clamping of the base to be processed is realized. The vertical lathe has good universality, the application range and the utilization rate of the vertical lathe equipment are improved, and the machining precision can still be ensured.

FIGS. 4 and 5 are top views of the present utility model;
fig. 6 is a partial enlarged view of fig. 1.
Detailed Description
The utility model provides a frock clamp that frame lathe work was used, set up down retainer plate 10 on workstation 1, the last port of retainer plate 10 is step hole 11, this step hole 11 department arranges retainer plate 20, the retainer plate 20 constitutes radial location, axial support cooperation with the lower extreme tang of the motor frame 2 of vertical arrangement, the lifter 30 of vertical arrangement has been arranged on workstation 1, the upper end of lifter 30 is articulated with the one end of swing arm 40 and is connected and articulated the axle core and be located the plumb and to, the other end dismantlement of swing arm 40 is connected with clamp plate 50.
According to the scheme disclosed by the utility model, the positioning ring 20 and the pressing plate 50 can be quickly replaced, so that the clamping tasks of motor bases 2 with different specifications can be met, the utilization rate of equipment is improved, and the machining precision is ensured.
Referring to fig. 1, 2 and 3, the upper end of the positioning ring 20 is a step-shaped opening edge, specifically, the opening of the upper end of the positioning ring 20 is surrounded by a built-in convex ring 22, when in specific use, the inner hole wall of the built-in convex ring 22 is surrounded on the peripheral wall of the spigot at the lower end of the motor base 2, and the top surface of the built-in convex ring 22 is propped against the spigot table surface at the lower end of the motor base 2, see fig. 6.
Preferably, as shown in fig. 3, the lower end of the positioning ring 20 is provided with an external convex ring 21. The lower edge of the convex ring 21 is horizontally arranged at the step hole 11, and the ring body at the upper part of the convex ring 21 can appropriately increase the axial dimension and reduce the radial dimension so as to be suitable for positioning the motor base 2 with a shorter axial dimension and a smaller radial dimension.
As shown in fig. 1, 2 and 3, the pressing plate 50 has various options, one of which is a small-sized plate body as shown in fig. 1; secondly, as shown in fig. 3, the plate surface is a flat plate body, the middle part of the plate body is provided with a weight reducing hole 51 which is penetrated up and down, and the plate body is large in size; thirdly, as shown in fig. 2, the pressing plate 50 has an i-shaped cross section, the web in the middle is perpendicular to the arm length direction of the swing arm 40, the pressing plate 50 is shaped like an i-shaped cross section, and the pressing plate has the advantages of high bending resistance and torsional strength and light weight.
Referring to the drawings, the lifting rod 30 is a piston type telescopic cylinder, and one end of the swing arm 40 is connected with a rotor piston 61 of a rotary cylinder 60 provided at the upper rod end of the piston rod of the lifting rod 30. It should be noted that, in a specific operation, when the pressing is released, the starting time of the displacement action of the lifting rod 30 should be earlier than or at least synchronous with the starting time of the rotation of the swing arm 40; when the swing arm 40 rotates in place during pressing the workpiece, the lifting rod 30 completes the final descending stroke, so that friction between the pressing plate 50 and the ear 3 on the motor base 2 during pressing or releasing the pressing can be avoided.
In addition, as shown in fig. 4 and 5, 4 lifting rods 30 are arranged around the fixing ring 10, so that the clamping of the motor base 2 provided with 4 lugs 3 shown in fig. 4 can be satisfied, and the clamping of the motor base 2 provided with 6 lugs 3 shown in fig. 5 can also be realized. In fig. 4 and 5, the platen 50 swings between a solid line position, which is a press-down position, and a broken line position, which is a press-release position, and the platen 50 shown in fig. 5 can select an angular plate edge profile.
