Description

Technical Field

[0001] This utility model belongs to the field of drilling positioning fixture technology, specifically relating to a positioning fixture for drilling a hydrogen-powered electric drive bridge speed limiting fixing block. Background Technology

[0002] In the manufacturing process of hydrogen-powered electric drive bridges, the speed limiting fixing block is a crucial component. This fixing block requires multiple high-precision holes to meet its requirements for connection, positioning, and functionality with other components within the electric drive bridge. Because cylindrical parts rely solely on the side of the part for support from the clamping force of the vise, the clamping force is relatively large, making the part prone to damage and deformation during operation. Furthermore, the lack of support on the bottom surface during drilling can easily lead to vertical displacement, resulting in poor part manufacturing accuracy and, in severe cases, damage to drilling tools or cutting tools. Even with clamping and fixing the part to the side, the bottom surface of the part still lacks support, making it susceptible to vertical displacement during drilling operations.

[0003] To address this, a drilling positioning fixture, with announcement number "CN212043580U", includes a drilling positioning plate, a first positioning block, a second positioning block, an adjusting locking clamp, and a locking device. The drilling positioning plate has a vertical through hole in its center. On the top surface of the drilling positioning plate, along the circumference of the vertical through hole, are a first guide groove, a second guide groove, and a third guide groove. These guide grooves intersect on the vertical central axis of the vertical through hole. The first positioning block, the second positioning block, and the adjusting locking clamp are slidably connected to the first guide groove, the second guide groove, and the third guide groove, respectively. The locking device is installed below the third guide groove, and the adjusting locking clamp is positioned and locked to the third guide groove via the locking device. This fixture can achieve both vertical support and fixation of the part, as well as horizontal clamping and positioning, thereby ensuring the drilling quality of the part, improving the production accuracy and efficiency of drilling, and reducing the labor intensity of workers.

[0004] However, although the aforementioned drilling positioning fixture can rotate the screw forward by rotating the handle in the forward direction, and the screw engages with the drive thread of the adjusting locking block through the rotating thread, causing the adjusting locking block to move towards the vertical through hole, thereby cooperating with the two positioning blocks to lock the part placed above the vertical through hole, the following obvious defects still exist in use: Since the position of the sliding clamping of the clamping block is fixed, the aforementioned drilling positioning fixture can only clamp the workpiece on the corresponding workpiece clamping surface, and cannot adjust the clamping position of the clamping block according to the fixed surface suitable for clamping on the outer side of the workpiece. Therefore, it is only suitable for clamping workpieces where all external directions are flat for drilling operations, thus narrowing the scope of application of the aforementioned positioning fixture. Utility Model Content

[0005] The purpose of this invention is to provide a positioning fixture for drilling the speed limiting fixing block of a hydrogen-powered electric drive bridge, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning fixture for drilling a speed-limiting fixing block for a hydrogen-powered electric drive bridge, comprising:

[0007] The fixture frame has a workpiece rotating seat at the bottom inner side for clamping and rotating the electric drive bridge speed limiting fixing block. The workpiece rotating seat has a lifting clamping seat at the end for clamping and lifting the electric drive bridge speed limiting fixing block. The lifting clamping seat has a clamping mechanism for adjusting the clamping position by sliding and rotating around.

[0008] The transverse block has a drilling servo motor at its bottom for vertically drilling the speed limiting fixing block of the electric drive bridge. The shaft of the drilling servo motor is equipped with a drilling splash guard to prevent debris from splashing during drilling. The upper end of the transverse block is equipped with a guide slider to guide the transverse block to move laterally.

[0009] Preferably, a rotary motor is provided at the center of the bottom inner side of the fixture frame, and the rotary motor shaft is fixed in the inner groove provided at the center of the bottom of the workpiece rotating seat, driving the rotation of the electric drive bridge speed limiting fixing block to perform drilling operations.

[0010] Preferably, a lifting cylinder is installed in the grooves on both sides of the end of the workpiece rotating seat, and the top of the lifting cylinder is fixed to the bottom of the lifting clamp, so as to realize the lifting and adjusting of the speed limiting sliding block of the electric drive bridge, so as to drill holes at different depths.

[0011] Preferably, the outer ring surface of the workpiece rotating seat is uniformly provided with a locking groove with internal thread, and the center position of the end of the workpiece rotating seat is provided with a cylindrical support block for supporting the vertical placement of the electric drive bridge speed limiting fixing block, which supports the center position of the workpiece to ensure that it remains horizontal during drilling.

[0012] Preferably, the clamping mechanism includes an orientation adjustment base plate evenly arranged in multiple positions of the lifting clamping seat. One end of the adjustment base plate is provided with a locking plate extending downward to the outside of the lifting clamping seat and having an adjustment locking rod. Each end of the adjustment base plate is provided with a strip-shaped sliding groove. A moving block is slidably arranged in the strip-shaped sliding groove through a guide rod. Each moving block is provided with a clamping block at its end, thereby realizing the pneumatic clamping and fixing of the electric drive bridge speed limiting fixing block.

[0013] Preferably, the lower end face of the adjusting base plate is provided with an azimuth slider, and the position of the azimuth slider corresponding to the end of the lifting clamp seat is provided with an annular groove for the azimuth slider to slide circumferentially. A fixing plate is provided on one side of the adjusting base plate, and a clamping cylinder is provided at the end of the fixing plate. One end of the clamping cylinder is fixedly connected to the clamping block, which can adjust the circumferential clamping orientation of the adjusting base plate so as to adjust it to a suitable clamping surface.

[0014] Preferably, the upper part of the fixture frame is provided with a guide bar, and the guide slider moves through the guide bar to slide laterally. One side of the lateral block is connected to a lateral cylinder, and the lateral cylinder is fixed to the outside of the fixture frame to drive the drilling servo motor to move laterally.

[0015] Preferably, the shaft of the drilling servo motor is provided with a fixed plate, and movable guide rods that can elastically extend and retract are provided through both sides of the fixed plate. The drilling splash guard is fixed to the bottom end of the movable guide rods. A drill bit that can be moved through to the inside of the drilling splash guard is provided at the bottom center of the fixed plate, so as to block and prevent splashing of waste chips generated in the drilling.

[0016] Compared with the prior art, the technical effects and advantages of this utility model are as follows: This positioning fixture for drilling the speed limiter fixing block of a hydrogen-powered electric drive axle utilizes a combination of an adjusting base plate, locking plate, strip groove, moving block, clamping block, orientation slider, clamping cylinder, and annular groove and locking groove on the lifting clamping seat. When clamping electric drive axle speed limiters with different clamping surface shapes, the adjusting base utilizes the sliding of the orientation slider within the annular groove, causing the locking plate and clamping block to move accordingly to adjust the clamping orientation. The clamping block is moved to a suitable clamping surface outside the electric drive bridge limiting fixing block. Then, the clamping block is pneumatically clamped and fixed by the clamping cylinder. This allows for the orientation adjustment of the clamping block according to the different clamping surfaces outside the electric drive bridge speed limiting fixing block of different shapes, so as to clamp and fix electric drive bridge speed limiting fixing blocks of different specifications, shapes and sizes. This enables electric drive bridge speed limiting fixing blocks of different specifications, sizes and shapes to be clamped for drilling operations, and solves the existing problems and defects mentioned in the background art.

[0017] By combining a drilling servo motor, a fixed plate, a flexible telescopic guide rod, a drilling splash guard, and a drill bit, the electric drive bridge speed limiting block held in the lifting clamp moves upward to contact the drill bit. The drill bit then drills into the electric drive bridge speed limiting block, allowing the drilling splash guard to cover the drilled area and block the splashing debris generated during drilling. As the lifting clamp slowly rises to perform deep drilling, the drilling splash guard moves upward with the guide rod, thus not affecting the deep drilling operation and preventing debris from splashing into the drilling equipment and causing malfunctions, thereby improving safety during the drilling process.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-3 This utility model provides a technical solution: a positioning fixture for drilling a speed-limiting fixing block for a hydrogen-powered electric drive bridge, comprising:

[0024] The fixture frame 1 has a workpiece rotating seat 2 at the bottom inner side for clamping and rotating the electric drive bridge speed limiting fixing block, so that the electric drive bridge speed limiting fixing block is clamped and rotated for drilling. The end of the workpiece rotating seat 2 is equipped with a lifting clamping seat 3 for lifting and lowering after clamping the electric drive bridge speed limiting fixing block, so that the height of the electric drive bridge speed limiting fixing block can be adjusted after clamping, so as to drill holes of different depths. The lifting clamping seat 3 has a clamping mechanism 4 for adjusting the clamping position by sliding and rotating around, so as to realize the pneumatic clamping and fixing of electric drive bridge speed limiting fixing blocks of different specifications, sizes and shapes.

[0025] The transverse block 5 has a drilling servo motor 6 at its bottom for vertically drilling the speed limiting fixing block of the electric drive bridge. This allows for drilling around the end of the speed limiting fixing block. The shaft of the drilling servo motor 6 is equipped with a retractable drilling splash guard 7 to prevent debris from splashing during drilling. This guard blocks debris generated during drilling and prevents it from splashing everywhere. The upper end of the transverse block 5 has a guide slider 8 for lateral movement, which ensures the stability of the drilling servo motor 6 during movement.

[0026] A rotary motor 9 is located at the center of the bottom inner side of the fixture frame 1, which drives the electric drive bridge speed limiting fixing block to rotate and adjust the drilling position. The rotating shaft of the rotary motor 9 is fixed in the inner groove at the center of the bottom of the workpiece rotating seat 2 to ensure the stability of the rotary motor 9 during operation. Lifting cylinders 10 are installed in the grooves on both sides of the end of the workpiece rotating seat 2 to drive the lifting clamp 3 to adjust the height so as to drill holes of different depths. The top of the lifting cylinder 10 is fixed to the bottom of the lifting clamp 3. The outer ring surface of the workpiece rotating seat 2 is uniformly provided with locking grooves 11 with internal threads to fix the position of the adjusting base plate 13 after adjustment. A cylindrical support block 12 is provided at the center of the end of the workpiece rotating seat 2 to support the vertical placement of the electric drive bridge speed limiting fixing block, which supports the center of the bottom of the electric drive bridge speed limiting fixing block.

[0027] The clamping mechanism 4 includes an orientation adjustment base plate 13 evenly arranged in multiple positions of the lifting clamping seat 3. One end of the adjustment base plate 13 is provided with a locking plate 14 extending downward to the outside of the lifting clamping seat 3 and having an adjustment locking rod, so that the adjustment base plate 13 slides accordingly during orientation adjustment. An adjustment locking rod is provided through the locking plate 14, and each end of the adjustment base plate 13 is provided with a strip-shaped sliding groove 15, so that the moving block 16 slides in the strip-shaped sliding groove 15. The moving block 16 is slidably mounted in the strip-shaped sliding groove 15 through a guide rod, which drives the clamping block 17 to move in a fixed position. The sliding block 16 is used to clamp the speed limiting block of the electric drive bridge. Each end of the sliding block 16 is provided with a clamping block 17 to clamp and fix the speed limiting block of the electric drive bridge. Each lower end face of the adjusting base plate 13 is provided with an azimuth slider 18 to keep the adjusting base plate 13 in a stable azimuth adjustment sliding. The azimuth slider 18 is provided with an annular groove 19 at the end of the lifting clamping seat 3 to allow the azimuth slider 18 to slide in a circle. One side of the adjusting base plate 13 is provided with a fixing plate, and the end of the fixing plate is provided with a clamping cylinder 20. One end of the clamping cylinder 20 is fixedly connected to the clamping block 17.

[0028] The upper part of the fixture frame 1 is provided with a guide bar 21, and the guide slider 8 slides laterally through the guide bar 21. The transverse block 5 is connected to a transverse cylinder 22 on one side, and the transverse cylinder 22 is fixed to the outside of the fixture frame 1. The shaft of the drilling servo motor 6 is provided with a fixed plate 23, and the fixed plate 23 is provided with elastically telescopic movable guide rods 24 on both sides. The drilling splash guard 7 is fixed to the bottom of the movable guide rods 24. The bottom center of the fixed plate 23 is provided with a drill bit 25 that moves through to the inside of the drilling splash guard 7, so as to realize drilling of holes at different depths after clamping and fixing the electric drive bridge speed limiting fixed block.

[0029] Specifically, in use, the electric drive bridge speed limiter fixing block is first placed at the end of the lifting clamp 3, and its center position is stably supported by the cylindrical support block 12. Then, the orientation of the clamping block 17 included in the clamping mechanism 4 is adjusted according to the different specifications, sizes and shapes of the electric drive bridge speed limiter fixing block. First, the orientation of the adjusting base plate 13 is adjusted by sliding the orientation slider 18 in the annular groove 19. The orientation sliding of the adjusting base plate 13 causes the locking plate 14 to move along the outside of the lifting clamp 3, and the clamping block 17 is also adjusted and slid to the appropriate clamping surface of the electric drive bridge speed limiter fixing block for clamping. Thus, the orientation of the clamping block 17 can be adjusted according to the different clamping surfaces on the outside of the electric drive bridge speed limiter fixing block of different shapes, so as to clamp and fix electric drive bridge speed limiter fixing blocks of different specifications, shapes and sizes. The position of the clamping block 17 is fixed by locking it in the corresponding locking groove 11 using the adjusting locking rod.

[0030] Subsequently, the clamping cylinder 20 pushes the moving block 16 to slide within the strip groove 15, causing the clamping block 17 to clamp and fix the corresponding electric drive bridge speed limiting fixing block from multiple directions. Then, the lifting cylinder 10 pushes the lifting clamping seat 3 upward so that the electric drive bridge speed limiting fixing block contacts the drill bit 25 at the drilling position, and the drilling splash guard 7 covers the outside of the drilling position to block the flying debris. The drilling servo motor 6 starts and drives the drill bit 25 to drill the electric drive bridge speed limiting fixing block. At this time, the drilling splash guard 7 rotates accordingly without affecting the drilling operation, and as the lifting clamping seat 3 slowly moves upward... The slow rise and fall allow for drilling at different depths on the electric drive bridge speed limiter fixing block. The drill splash guard 7 rotates with the movable guide rod 24. After drilling is completed, the lifting clamp 3 moves the electric drive bridge speed limiter fixing block down. At this time, the rotary motor 9 starts and drives the electric drive bridge speed limiter fixing block to rotate and adjust the drilling position so that drilling can be performed at different positions. At the same time, the transverse cylinder 22 pushes the transverse block 5 and the guide slider 8 slides on the guide crossbar 21 to adjust the drilling spacing so that drilling can be performed at any position on the end of the electric drive bridge speed limiter fixing block.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
