Description

Technical Field

[0001] This utility model belongs to the field of wear-resistant precision steel processing technology, specifically relating to a positioning fixture for precision grinding of wear-resistant steel. Background Technology

[0002] In casting production, due to limitations in the fixtures and tooling used, workers often need to perform tedious tasks such as dial indicator adjustments and support during processing, which seriously affects product production and makes it impossible to guarantee the fixed positioning of the product. This also consumes a large amount of labor, resulting in high workload and low production efficiency, severely restricting the development of enterprises. A search revealed that application number "CN202022308136.2" discloses "a positioning fixture for precision grinding of wear-resistant steel parts," which describes "a steel frame capable of stably clamping flat or curved surfaces, reducing the adjustment of the grippers, and limiting the height, improving the accuracy of the limit, meeting the needs of rapid clamping, positioning, and grinding, and improving production efficiency." While the use of a steel frame capable of stably clamping flat or curved surfaces, reducing the adjustment of the grippers, and limiting the height does indeed improve the accuracy of the limit, meet the needs of rapid clamping, positioning, and grinding, and improve production efficiency, the above-mentioned document still has the following problems in actual use: In actual use, the clamping head cannot be replaced. If it encounters irregularly shaped or other workpieces, it will not be able to clamp stably. Furthermore, the clamping force cannot be adjusted according to different workpieces, which can easily damage the workpieces.

[0003] Therefore, providing a fixture that can quickly change the clamping head and adjust the clamping force according to different workpieces is of great practical value. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning fixture for precision grinding of wear-resistant steel, in order to solve the above-mentioned technical problems.

[0005] This utility model provides a positioning fixture for precision grinding of wear-resistant steel, including a connecting seat, a quick-change component, and an adjustment component.

[0006] The connecting seat has several sliding grooves at one end and an installation head at the other end. Several moving blocks are slidably connected inside the sliding grooves, and two connecting plates are provided at one end of each moving block. The quick-change component package is set in a clamping head that is inserted and connected to one end of the connecting plate. A limiting frame is inserted and connected inside the connecting plate and the clamping head. A limiting head is inserted and connected to the bottom of the limiting frame. A moving strip is provided at one end of the limiting head. A grip is provided at the bottom of the moving strip. Two limiting rods are slidably connected inside the moving strip. The adjustment assembly includes protective boxes on both sides of the connecting seat, two auxiliary rods on the inner wall of the connecting seat, two adjustment plates slidably connected to the outer walls of the two auxiliary rods, and springs on the outer walls of the two adjustment plates. One adjustment plate has several electro-hydraulic rods on its top, and the other adjustment plate has the same structure at its bottom.

[0007] In one embodiment of this utility model, the reset assembly includes a connecting frame disposed at one end of the moving bar. Both sides of the connecting frame are hinged to hinge seats via connecting rods. Each end of the two hinge seats is provided with an auxiliary block. A connecting rod is slidably connected inside each of the two auxiliary blocks. A fixing frame is disposed on the outer wall of the two connecting rods. The top of the fixing frame is fixedly connected to the connecting plate. Two damping rod springs are disposed at one end of the connecting frame. One end of each of the two damping rod springs is fixedly connected to the fixing frame.

[0008] In one embodiment of this utility model, each end of the two limiting rods is provided with a support plate, and the top of the plurality of support plates is fixedly connected to the connecting plate.

[0009] In one embodiment of this utility model, electric cylinders are provided at the top and bottom of the connecting seat, and the output shaft ends of the two electric cylinders are provided with moving heads through the inner wall of the connecting seat. The ends of the two moving heads are fixedly connected to several moving blocks.

[0010] In one embodiment of this utility model, the outer walls of both moving heads are fixedly connected to springs, and the interiors of both moving heads are slidably connected to auxiliary rods.

[0011] In one embodiment of this utility model, the tops of several electro-hydraulic rods are fixedly connected to the tops of the inner walls of two protective boxes. An auxiliary groove is provided at the connection between the connecting seat and the protective box. The outer walls of the two adjusting plates are slidably connected to the auxiliary groove. A controller is provided at the top corner of the connecting seat.

[0012] In one embodiment of this utility model, both the electro-hydraulic rod and the electric cylinder are electrically connected to the controller, and the controller is electrically connected to an external power supply.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1) When grinding different wear-resistant steels, the user can hold the handle and pull it to one end to move the moving bar. The moving bar moves on the limit rod and causes the limit head to slide out of the limit frame, releasing the limit frame. At this time, the user holds the limit frame and pulls it upward to release the limit of the clamping head. The user pulls the clamping head to one end to remove the clamping head and replace it with a different clamping head. After that, the limit frame is reinstalled and the limit head is reset by the reset component to reset the limit frame again, thereby achieving the purpose of quickly changing the clamping head to adapt to different shapes of wear-resistant steels. 2) When in use, the controller opens the electric hydraulic rod, which drives the adjusting plate to move. The movement of the adjusting plate will cause the spring to contract or expand under force, thereby changing the spring's preload. This makes it easier for the electric cylinder to drive the moving head to move. When the moving head drives the moving block and finally drives the clamping head to clamp the material, it can make the resistance it experiences greater or less, indirectly changing the clamping force to adapt to different stresses on wear-resistant steel, thus improving applicability and achieving the purpose of adjusting the clamping force.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Example Please see Figure 1-6 A positioning fixture for precision grinding of wear-resistant steel includes a connecting seat 100, a quick-change component 200, and an adjustment component 300.

[0017] Please refer to the details. Figure 1 The connecting seat 100 has several sliding grooves at one end and an installation head at the other end. Several moving blocks 110 are slidably connected inside the sliding grooves, and two connecting plates 120 are provided at one end of each moving block 110.

[0018] Please see Figure 5-6 The quick-change component 200 is provided with a clamping head 210 that is inserted and connected to one end of the connecting plate 120. A limit frame 220 is inserted and connected inside the connecting plate 120 and the clamping head 210. A limit head 230 is inserted and connected to the bottom of the limit frame 220. A moving strip 240 is provided at one end of the limit head 230. A grip 250 is provided at the bottom of the moving strip 240. Two limit rods 260 are slidably connected inside the moving strip 240.

[0019] In one specific embodiment, the clamping head 210 facilitates the grinding of different wear-resistant steels. The user can grip the handle 250 and pull it to one end, thereby moving the moving bar 240. The moving bar 240 moves on the limiting rod 260, causing the limiting head 230 to slide out of the limiting frame 220, releasing the limitation on the limiting frame 220. At this time, the user can grip the limiting frame 220 and pull it upwards to release the limitation on the clamping head 210. The user can then pull the clamping head 210 to one end to disassemble and replace it with a different clamping head 210. After that, the limiting frame 220 is reinstalled, and the limiting head 230 is reset by the reset component 400, re-limiting the limiting frame 220. This allows for quick replacement of the clamping head 210 to adapt to different shapes of wear-resistant steels.

[0020] Please see Figure 3-4The adjustment assembly 300 includes protective boxes 310 on both sides of the connecting seat 100. The inner wall of the connecting seat 100 is provided with two auxiliary rods 320. The outer walls of the two auxiliary rods 320 are slidably connected with two adjustment plates 330. The outer walls of the two adjustment plates 330 are provided with springs 340. The top of one adjustment plate 330 is provided with several electric hydraulic rods 350, and the bottom of the other adjustment plate 330 is provided with the same structure as its top.

[0021] In one specific embodiment, the provided electro-hydraulic rod 350 allows the controller to open the electro-hydraulic rod 350 during use, causing the electro-hydraulic rod 350 to move the adjusting plate 330. The movement of the adjusting plate 330 will cause the spring 340 to contract or expand under force, thereby changing the preload of the spring 340. This facilitates the movement of the moving head 700 by the electric cylinder 600, which in turn drives the moving block 110 to ultimately drive the clamping head 210 to clamp the material. This allows for a greater or lesser resistance to the material, indirectly changing the clamping force to adapt to different stresses on wear-resistant steel, improving applicability, and thus achieving the purpose of adjusting the clamping force.

[0022] Please see Figure 6 The reset assembly 400 includes a connecting frame 410 disposed at one end of the moving bar 240. Both sides of the connecting frame 410 are hinged to hinge seats 430 via connecting rods 420. Each end of the two hinge seats 430 is provided with an auxiliary block 440. Each auxiliary block 440 is slidably connected to a connecting rod 450. The outer wall of the two connecting rods 450 is provided with a fixing frame 460. The top of the fixing frame 460 is fixedly connected to the connecting plate 120. One end of the connecting frame 410 is provided with two damping rod springs 470. One end of each damping rod spring 470 is fixedly connected to the fixing frame 460.

[0023] In one specific embodiment, the movable bar 240 facilitates the movement of the connecting frame 410. The movement of the connecting frame 410 pushes the hinge seat 430 to move via the connecting rod 420. The hinge seat 430 moves on the connecting rod 450 via the auxiliary block 440 for assistance. The movement of the connecting frame 410 causes the damping rod spring 470 to contract and store force. When the user replaces the clamping head 210, the user releases the grip handle 250 to reset the damping rod spring 470, which in turn resets other parts, thereby resetting the limiting head 230 and re-limiting the limiting frame 220, thus achieving the purpose of resetting.

[0024] Please see Figure 6 Both ends of the two limit rods 260 are provided with support plates 500, and the tops of several support plates 500 are fixedly connected to the connecting plate 120.

[0025] In one specific embodiment, the support plate 500 facilitates the support and fixation of the limiting rod 260, making the limiting rod 260 more stable during use, avoiding wobbling and improving stability.

[0026] Please see Figure 3 Electric cylinders 600 are provided at the top and bottom of the connecting seat 100, and moving heads 700 are provided at the output shaft ends of the two electric cylinders 600 through the inner wall of the connecting seat 100.

[0027] In one specific embodiment, the electric cylinder 600 is provided so that the controller can open the electric cylinder 600 during use, so that the electric cylinder 600 drives the moving head 700 to move, which in turn drives the moving block 110 to move. The movement of the moving block 110 will eventually drive the clamping head 210 to clamp and position the material.

[0028] Please see Figure 3 The outer walls of both moving heads 700 are fixedly connected to the spring 340, the interiors of both moving heads 700 are slidably connected to the auxiliary rod 320, and the ends of both moving heads 700 are fixedly connected to several moving blocks 110.

[0029] In one specific embodiment, the auxiliary rod 320 is provided to limit the movement of the moving head 700, making it more stable during movement and avoiding swaying.

[0030] Please see Figure 4 The tops of several electric hydraulic rods 350 are fixedly connected to the tops of the inner walls of two protective boxes 310. An auxiliary groove is provided at the connection between the connecting seat 100 and the protective box 310. The outer walls of the two adjusting plates 330 are slidably connected to the auxiliary groove. A controller is provided at the top corner of the connecting seat 100.

[0031] In one specific embodiment, the protective box 310 provides convenient protection for the internal parts during use, preventing damage to the internal parts due to bumps and knocks, and improving stability.

[0032] Please see Figure 1-6 Both the electric hydraulic rod 350 and the electric cylinder 600 are electrically connected to the controller, which is electrically connected to an external power source.

[0033] In one specific embodiment, a controller is provided to facilitate power supply control of electrical equipment, enabling the equipment to be powered on when needed, thus avoiding situations where power cannot be supplied when power is required.

[0034] In use, the clamping head 210 facilitates grinding different wear-resistant steels. The user can grip the handle 250 and pull it to one end, causing the moving bar 240 to move. The moving bar 240 moves on the limiting rod 260, causing the limiting head 230 to slide out of the limiting frame 220, releasing the limitation on the limiting frame 220. The user can then pull the limiting frame 220 upwards to release the limitation on the clamping head 210. Afterwards, the user can pull the clamping head 210 to one end to disassemble it and replace it with a different clamping head 210. The limiting frame 220 is then reinstalled, and the limiting head 230 is reset via the reset assembly 400, re-limiting the limiting frame 220. This allows for quick replacement of the clamping head 210 to accommodate different shapes of wear-resistant steel. The included electro-hydraulic rod 350 allows the controller to open it during use, causing the adjusting plate 330 to move. This movement of the adjusting plate 330 causes the spring 340 to contract or expand, changing its preload. This allows the electric cylinder 600 to move the moving head 700, which in turn moves the moving block 110, ultimately clamping the material with the clamping head 210. This adjusts the clamping force, allowing for greater or less resistance to the material, thus adapting to different stresses on the wear-resistant steel and improving its applicability. This achieves the goal of adjusting the clamping force.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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.
