Description
Technical Field
The invention relates to the field of aerospace, electromagnetic ejection/emission or ultra-high operation test, in particular to a high-precision splicing structure and method of an ultra-high speed guide rail.
Background
The high-precision guide rail is generally processed by a grinding machine, the processing precision can reach an error below 0.02mm, and is limited by the processing capacity of the machine tool, and the single guide rail is generally 3 to 5 meters long. In order to meet longer use requirements in the practical use process of the guide rail, guide rail splicing is a common means, and the stability and splicing accuracy of the joint position of the guide rail directly influence the use effect of the guide rail. A more stable and reliable joint is a key technology in the application of the guide rail.
At present, the application scene of the high-speed guide rail in the general industry (the fields of automatic production and the like) is that the speed max=4m/s, the main straight sides of the guide rail are directly connected face to face, and as shown in fig. 1 and 2, the two sides of the guide rail are working surfaces. The traditional joint form meets the use requirement on the current use environment with the speed less than or equal to 4m/s, the precision of the joint (the height, the width, the arc-shaped profile, the surface roughness and the like of the guide rail) is completely ensured by the machining precision of the guide rail, the contact surface of the connecting guide rail is also ensured by the machining precision, and the good joint precision can be ensured in the initial stage of installation.
Shortcomings of the traditional splicing mode: as shown in fig. 3 and 4. 1) After long-time use, if the bolt loosens, the guide rail machining precision is insufficient, there are flaws, insufficient rigidity, abrasion, deformation or reasons such as insufficient primary installation precision, the guide rail moves/slides to the left and right sides, the height difference h is generated or enlarged, the protruding height can exceed the design index, steps with different heights can be generated on the side face, the moving parts on the guide rail are blocked, if the thrust is large, the risk of the integral damage of the guide rail or equipment is possibly caused, and the risk and the harm are synchronously improved along with the improvement of the running speed of the sliding block on the guide rail. 2) The seam width of the guide rails at the two ends can be increased, and the seam width d of the guide rails can generate additional harmful vibration and planing phenomenon when the sliding block or the roller passes through, so that the service life of the sliding block or the roller or the ball is seriously influenced. 3) The seam accuracy of the guide rail is easily affected by the accuracy of the mounting surface. 4) When the external load is large, the height difference h and the seam width d are also increased, and the stable running state is affected.
In the aerospace test field, the ultra-high operation test field, the electromagnetic ejection or electromagnetic emission guide rail or the high-speed emission guide rail and the like, the speed of the guide rail can reach more than 1 Mach (340.3 m/s), even the guide rail is more common to several Mach, the traditional guide rail joint mode exposes serious risk hidden dangers, the guide rail with the Mach speed level is generally longer (the length can reach several kilometers to tens of kilometers), the joint of each guide rail is a risk point, and if any one of the risks can cause disastrous consequences.
The mode that the piece of high-speed guide rail adopted at present often is: and (5) secondarily polishing the joint by adopting a welding machine after splicing. This approach is more efficient, but secondary grinding is done manually or semi-automatically on the installation site (mostly in outdoor construction), and secondary grinding accuracy is low (only the highest accuracy of 0.1mm error can be achieved), which is far from adequate for high-speed guide rails with strict vibration requirements.

When the guide rail is used for a long time, the guide rail is deviated, the height difference h is generated or enlarged, and the width d of the guide rail joint is increased.
Example 1
As shown in fig. 5 to 11, the present embodiment provides a high-precision splicing structure of an ultra-high speed rail, which is characterized by comprising a first rail 1, a second rail 2 and a first taper bolt 3,
one side of the end part of the first guide rail 1 is provided with a first extension block 101 which extends outwards along the length direction, a first gap is formed at the other side or the middle part of the first extension block 101, the first extension block 101 is provided with a first taper hole and a first unthreaded hole which are coaxially arranged and communicated, one side of the end part of the second guide rail 2 is provided with a second gap, the other side or the middle part of the second guide rail 2 is provided with a second extension block 201 which extends outwards along the length direction, the second extension block 201 is provided with a threaded hole, the first extension block 101 is spliced with the second gap, the second extension block 201 is spliced with the first gap,
the diameter of the first unthreaded hole is larger than that of the threaded hole, the first unthreaded hole is eccentrically arranged relative to the threaded hole and far away from the direction of the second guide rail 2, the first taper bolt 3 comprises a first taper bolt head and a first screw rod which are sequentially connected, the first screw rod penetrates through the first unthreaded hole and is in threaded connection with the threaded hole, the first taper bolt head is positioned in the first taper hole, and the taper angle alpha of the first taper bolt head and the taper angle alpha of the first taper hole are the same.
In this scheme, first extension piece 101 is pegged graft with the second vacancy, and second extension piece 201 is pegged graft with first vacancy, realizes the grafting location of two guide rails. Subsequently, the first taper bolt 3 passes through the first light hole and is screwed with the screw hole. Because first unthreaded hole and screw hole eccentric settings, the in-process of screw hole is twisted to first taper bolt 3, first taper bolt head and first taper hole shape adaptation play the centering effect, and first taper bolt head exerts its radial effort to the lateral wall of first taper hole for first guide rail 1 and second guide rail 2 remove in opposite directions and compress tightly, and first unthreaded hole has the motion trend that removes to coaxial with the screw hole.
The novel guide rail joint structure solves the problem that the joint precision is reduced after use, and welding and polishing of joints on an installation site are not needed. The purpose of small guide rail seam error is achieved, and the overall quality and performance stability of the assembled guide rail are improved. The method has the following advantages:
1) The joint width is automatically tightened after the first guide rail 1 and the second guide rail 2 are installed, and the installation accuracy is improved.
2) The guide rails can be connected into a whole by adopting the splicing structure, are not easy to separate due to external influence, and have higher structural stability at the joint positions.
3) Simple structure, easy installation, no need of complex and difficult control operations such as welding and polishing the joints on site.
4) And decoupling the guide rail splicing precision and the mounting surface precision. The accuracy of the joint of the guide rail is not affected by the accuracy of the guide rail and the mounting surface, and the joint accuracy of the guide rail completely depends on the accuracy of the guide rail during assembly.
Specifically, the longitudinal direction of the first rail 1 and the second rail 2 is the X-axis direction shown in fig. 5 and 6. The first guide rail 1 and the second guide rail 2 are assembled into a guide rail group, two sides of the Y direction of the guide rail group are working surfaces 5, and one side of the Z direction of the guide rail group is a fixed installation side 8 as shown in fig. 6. The fixed mounting side 8 can be fixedly connected with other components in various mounting structures, such as bolt holes, clamping grooves, T-shaped structures or mounting flanges and the like are formed on the fixed mounting side 8.
Specifically, the manufacturing dimensions of the matched parts of the outer profiles (except the first conical hole, the first unthreaded hole and the threaded hole) of the first guide rail 1 and the second guide rail 2 are the same, and the machining precision is the same. The dimensional accuracy of the end part of the guide rail is ensured by mechanical processing, and the mechanical manufacturing technology of the guide rail is easy to realize.
Specifically, the diameter Φw of the first unthreaded hole of the first guide rail 1 is larger than the nominal diameter Q of the threaded hole of the second guide rail 2 of the guide rail 2 by a certain size, and the diameter Φw needs to provide a movement allowance in the X direction for the step 2 of the splicing method.
Specifically, after the first guide rail 1 and the second guide rail 2 are spliced, as the two guide rails have the same external dimensions, the splice is in a smaller state, the first unthreaded hole and the threaded hole are positioned at the eccentric position, after the first taper bolt 3 is assembled, the first taper bolt 3 further tightens the first guide rail 1 and the second guide rail 2 in opposite directions by the X-direction component force of the first taper bolt 3 on the first guide rail 1, the splice is reduced, and the assembly precision is improved. As shown in fig. 8, the dimension D1 is slightly larger than the dimension E2.
Among them, note is: the first taper hole position of the first guide rail 1 and the screw hole position of the second guide rail 2 need to avoid the working surface of the sliding block or the roller.
On the basis of the technical scheme, at least one end of the first taper bolt 3 is welded and fixed with the first guide rail 1 or the second guide rail 2.
By welding and fixing, the first conical bolt 3 is prevented from loosening (as long as the welding method is proper, the welding temperature rise is controlled, and the damage of annealing and softening of the bolt or thermal deformation of the guide rail can not be caused). As long as the first taper bolt 3 is not loosened after the ultra-high speed guide rail is assembled, the height difference h between the guide rail joint d and the working surface cannot be increased, and further the precision cannot be lost.
Specifically, after the first taper bolt 3 is tightened to reach the designed pretightening force, at least one end of the first taper bolt 3 is fixed and loosened by spot welding in a welding manner. The welding requires control of heat and heat affected zone size, such as laser welding or cold welding. Specifically, two welding points are arranged at one end of the first taper bolt 3, or one welding point is arranged at each of two ends of the first taper bolt 3. When the guide rail is used in good conditions or maintenance and replacement of the guide rail are considered, high-strength thread compound can be used for replacing the welding spots, so that the fixing and anti-loose effects are achieved.
On the basis of the above technical solution, the first extension block 101 is provided with a plurality of corresponding communicated first tapered holes and first unthreaded holes at intervals along the width direction thereof, the second extension block 201 is provided with a plurality of corresponding threaded holes at intervals along the width direction thereof, and the first tapered bolts 3 are provided with a plurality of corresponding threaded holes.

Specifically, the first extension block 101 is located at one side of the first rail 1 in the Y direction, the second extension block 201 is located at the other side of the second rail 2 in the Y direction, and the joint between the first rail 1 and the second rail 2 is zigzag.
Specifically, the total length of the first taper bolt 3 is smaller than the total thickness of the first extension block 101 and the second extension block 201 in the Y direction, and the two ends of the first taper bolt 3 do not extend out of the first extension block 101 and the second extension block 201, so that the sliding block work on the guide rail is prevented from being influenced.
Specifically, as shown in fig. 8, the Y-direction dimensions of the first guide rail 1 and the second guide rail 2 are N, the Y-direction dimensions of the first extension block 101 and the second void are B, the Y-direction dimensions of the second extension block 201 and the first void are a, and the X-direction dimensions of the first extension block 101 and the second extension block 201 are C.

The first taper bolt head end side wall is welded with the first taper hole side wall, and the first screw end side wall is welded with the screw hole side wall. The height of the solder after welding does not protrude from the height of the working surface of the guide rail.

A second extension block 201 in the middle of the second guide rail 2 is inserted in the first gap between the first extension block 101 and the third extension block 102.

Example six
On the basis of any one of the first to fifth embodiments, the present embodiment further provides a high-precision splicing method for an ultra-high speed guide rail, which is implemented by adopting the high-precision splicing structure for an ultra-high speed guide rail, and includes the following steps:
step 1: inserting the first extension block 101 into the second recess while inserting the second extension block 201 into the first recess;
step 2: the first screw rod of the first taper bolt 3 penetrates through the first unthreaded hole, the first taper bolt 3 is rotated to be in threaded connection with the threaded hole, in the process of rotating the first taper bolt 3, the first taper bolt head presses the side wall of the first taper hole, and the first guide rail 1 and the second guide rail 2 move in opposite directions and are locked.
The beneficial effects are that: the guide rail splicing operation is easy, and complex and uncontrollable operations such as on-site welding and polishing are not needed. The guide rail seam error is smaller, and the overall quality and performance stability of the assembled guide rail are high.
When the first guide rail 1 and the second guide rail 2 are spliced, the end parts of the two guide rails are matched in shape and are buckled mutually, and the first conical bolt 3 and the threaded hole are screwed and fixed. As the first taper bolt 3 is screwed down, the right side of the taper surface of the first taper bolt head will be positioned to press the right side of the first taper hole of the first guide rail 1 (as shown in fig. 5), the pretightening force of the bolt generates a component force (X direction) along the horizontal direction through the taper surface, and the horizontal component force will push the first guide rail 1 to the direction of the second guide rail 2 for pressing. The pretightening force of the bolt compresses the two guide rails in the Y direction along the Y direction. Because the conical surface is neutral, the Z direction of the guide rail tends to be centered due to the guiding effect of the first conical bolt head, and a certain installation precision is obtained.
For the technical solution of the fifth embodiment, the high-precision splicing method further includes: step 3: the second screw rod of the second taper bolt 4 passes through the second light hole, the second taper bolt 4 is rotated to be in threaded connection with the threaded hole, the second taper bolt head extrudes the side wall of the second taper hole in the process of rotating the second taper bolt 4, and the first guide rail 1 and the second guide rail 2 move in opposite directions and are locked.
