Description

Technical Field

[0001] This utility model relates to the field of machining tool technology, specifically to a testing fixture for PCB machining tools. Background Technology

[0002] PCB machining tools are mainly used for cutting, drilling, milling, engraving, and other processing steps, helping operators perform precise and meticulous PCB machining to produce high-quality and high-performance PCB boards. The use of PCB machining tools can greatly improve processing efficiency and accuracy, while reducing processing costs and time.

[0003] Chinese patent CN214238237U discloses a tool clamping device for a PCB tool inspection production line. The device uses a horizontally arranged slide rail to move the clamp horizontally and a lifting cylinder to move the clamp up and down. This tool clamping device can be used to automatically clamp and load tools during the PCB tool size inspection process. It can then be used in conjunction with machine vision inspection equipment to detect tool dimensions, thereby improving inspection efficiency.

[0004] The aforementioned equipment can automatically clamp PCB processing tools during use. However, due to the design limitations of the fixture, it can only clamp tools of a single shape. When producing tools of different shapes, the fixture needs to be changed to adapt to the new tool shape. However, in the current device, the fixture is fixed to the piston rod by bolts or welding, which makes it difficult for operators to change the fixture, greatly increasing the change time and reducing the inspection efficiency. Optimization and improvement are needed. Utility Model Content

[0005] The purpose of this invention is to provide a testing fixture for PCB processing tools, so as to solve the problem of cumbersome fixture replacement mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A testing fixture for PCB processing tools includes: a piston rod on which a fixture body is mounted; a replacement component on the piston rod, comprising a mounting block on the piston rod, a handle on the mounting block, an elliptical part at one end of the handle, and an inclined block inside the mounting block; the replacement component is used for replacing the fixture body; and a locking component on the handle, comprising a telescopic rod on the handle, and a limit post on the handle; the locking component is used for fixing the handle.

[0008] Preferably, the replacement component also includes elastic members disposed on both sides inside the mounting block, with a fixing plate at one end of the elastic member and an inclined block disposed on one side of the fixing plate.

[0009] Preferably, a connecting rod is provided on one side of the fixing plate, a fixing groove is provided on one side of the connecting rod, and a fixing member is provided on the outer side of the elliptical part corresponding to the fixing groove, and the fixing member is movably disposed inside the fixing groove.

[0010] Preferably, a connecting plate is provided on the top of the fixture body, and a positioning block is provided on the top of the connecting plate.

[0011] Preferably, the mounting block has a positioning groove inside corresponding to the positioning block, and the positioning block is movably positioned in the positioning groove.

[0012] Preferably, inclined grooves are provided on both sides of the positioning block corresponding to the inclined blocks, and the inclined blocks are movably disposed in the inclined grooves.

[0013] Preferably, the bottom of the fixing plate is provided with sliders on both sides, and the mounting block is provided with grooves corresponding to the sliders, with the sliders being movably disposed in the grooves.

[0014] Preferably, the locking assembly further includes a connecting groove disposed within the telescopic rod, and a limiting hole is provided on the mounting block corresponding to the limiting post, with the limiting post being movably disposed within the limiting hole.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By controlling the rotation of the handle, the operator can easily rotate the elliptical part, which in turn can cooperate with the elastic part to drive the connecting rod to move, thereby allowing the inclined block to slide into the inclined groove and fix the fixture body inside. This allows the operator to quickly replace the fixture body as needed.

[0017] After the fixture body is replaced, pressing the handle allows the limiting pin to slide into the limiting hole, thus fixing the handle and preventing accidental rotation of the handle due to external factors. This ensures that the inclined block can be stably locked in the inclined groove. Attached Figure Description

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0027] like Figure 1 - Figure 6 As shown, this application provides a testing fixture for PCB processing tools, including: a piston rod 1, a fixture body 2 disposed on the piston rod 1, a replacement component disposed on the piston rod 1, the replacement component including a mounting block 4 disposed on the piston rod 1, a handle 9 disposed on the mounting block 4, an elliptical part 17 disposed at one end of the handle 9, and an inclined block 8 disposed inside the mounting block 4, the replacement component being used for replacing the fixture body 2.

[0028] Specifically, such as Figure 6 As shown, the replacement component also includes elastic elements 16 disposed on both sides inside the mounting block 4. One end of the elastic element 16 is provided with a fixing plate 15, and the inclined block 8 is disposed on one side of the fixing plate 15. Through the elastic force of the elastic element 16, a pushing force can be given to the inclined block 8, which makes it easier for the operator to control the inclined block 8 to slide into the inclined groove 7.

[0029] Specifically, such as Figure 6As shown, a connecting rod 19 is provided on one side of the fixing plate 15, and a fixing groove 21 is provided on one side of the connecting rod 19. A fixing member 18 is provided on the outer side of the elliptical part 17 corresponding to the fixing groove 21. The fixing member 18 is movably disposed inside the fixing groove 21. Through the cooperation between the fixing member 18 and the fixing groove 21, the elliptical part 17 can be connected to the connecting rod 19, thereby facilitating the control of the movement of the connecting rod 19.

[0030] Specifically, such as Figure 2 As shown, a connecting plate 3 is provided on the top of the fixture body 2, and a positioning block 6 is provided on the top of the connecting plate 3. The positioning block 6 makes it easier for the staff to fix the fixture body 2 better.

[0031] Specifically, such as Figure 3 As shown, the mounting block 4 has a positioning groove 5 inside corresponding to the positioning block 6. The positioning block 6 is movably set in the positioning groove 5. By cooperating with the positioning groove 5, the pre-positioning of the fixture body 2 can be achieved.

[0032] Specifically, such as Figure 6 As shown, inclined grooves 7 are provided on both sides of the positioning block 6 corresponding to the inclined blocks 8. The inclined blocks 8 are movably disposed in the inclined grooves 7. The fixture body 2 is fixed by the inclined blocks 8 being inserted into the inclined grooves 7.

[0033] Specifically, such as Figure 6 As shown, sliders 20 are provided on both sides of the bottom of the fixed plate 15, and a groove 14 is provided inside the mounting block 4 corresponding to the sliders 20. The sliders 20 are movably disposed in the groove 14, which can limit the movement direction of the fixed plate 15.

[0034] The handle 9 is provided with a locking component, which includes a telescopic rod 12 provided on the handle 9 and a limit post 11 provided on the handle 9. The locking component is used to fix the handle 9.

[0035] Specifically, such as Figure 4 As shown, the locking assembly also includes a connecting groove 13 disposed in the telescopic rod 12, and a limiting hole 10 is provided on the mounting block 4 corresponding to the limiting post 11. The limiting post 11 is movably disposed in the limiting hole 10. Through the cooperation between the limiting post 11 and the limiting hole 10, the handle 9 is fixed after adjustment.

[0036] In this embodiment: by controlling the rotation of the handle 9, the elliptical part 17 can be rotated, thereby allowing the inclined block 8 to be inserted into the inclined groove 7, thus fixing the fixture body 2. This makes it convenient for the staff to replace the fixture body 2 as needed. After the fixture body 2 is replaced, by controlling the limit post 11 to slide into the limit hole 10, the handle 9 can be fixed, thereby preventing external factors from causing the handle 9 to rotate, and allowing the inclined block 8 to be firmly inserted into the inclined groove 7, thus fixing the fixture body 2.

[0037] The specific solution is as follows: When the fixture body 2 needs to be replaced, the operator rotates the handle 9, which drives the elliptical part 17 to rotate, causing the fixing part 18 to slide inside the fixing groove 21. This allows the elliptical part 17 to press against the connecting rod 19, causing the inclined block 8 to retract into the mounting block 4. By controlling the positioning block 6 to slide into the positioning groove 5, the fixture body 2 is pre-positioned. Then, by controlling the handle 9 to rotate back to its original position, the slider 20 slides inside the sliding groove 14. Through the elastic force of the elastic part 16, a pushing force is applied to the inclined block 8 as it moves, facilitating its better movement. This allows the inclined block 8 to quickly and stably engage inside the inclined groove 7, thus fixing the fixture body 2. After the fixture body 2 is replaced, the handle 9 rotates back to its original position. By pressing the handle 9, the limiting post 11 slides into the limiting hole 10, thus fixing the handle 9. This ensures that the inclined block 8 is firmly engaged inside the inclined groove 7, thus fixing the fixture body 2.

[0038] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary; within the framework of this invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this invention as described above, which are not provided in detail for the sake of brevity.

[0039] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
