Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing tools, specifically to an auxiliary tapping fixture for sheet metal parts. Background Technology

[0002] Sheet metal parts are a common type of component in industrial production. Sometimes, in order to connect sheet metal parts with other components, it is necessary to drill holes and tap threads on the sheet metal parts so that they can be used with bolts.

[0003] like Figure 1 Currently, there is a sheet metal part that needs tapping. The sheet metal part includes a main body, and support plate 1, support plate 2 and support plate 3 connected to both sides of the main body. Support plate 1 and support plate 2 are both inclined. Support plate 3 is flush with the main body and extends outward. Drilling and tapping are required on the main body, support plate 1, support plate 2 and support plate 3.

[0004] There are currently two main approaches:

[0005] 1. An in-mold tapping structure is set inside the mold, and tapping is completed directly after the sheet metal part is stamped. The disadvantages of this approach are that the mold structure is complex, the mold maintenance is difficult, the defect rate is high, and defective products are easy to flow out.

[0006] 2. Manual tapping is performed on each surface using a tapping machine; the disadvantage is that it requires multiple clamping operations and positioning is inconvenient.

[0007] There is an urgent need to provide a solution for convenient tapping of the aforementioned sheet metal parts. Utility Model Content

[0008] Based on the above description, this utility model provides an auxiliary tapping fixture for sheet metal parts to solve the problem that multiple positioning and clamping are required when tapping holes on multiple different surfaces, which affects processing efficiency.

[0009] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A sheet metal auxiliary tapping fixture, including a positioning component for positioning the sheet metal part and a clamping component for clamping the sheet metal part;

[0010] The positioning component includes a positioning base and a positioning flange. The positioning flange fits against the side of the sheet metal part, and the positioning base is provided with a support surface that fits against the sheet metal part.

[0011] The clamping assembly includes a clamping block and a connecting rod, with the clamping block extending toward the main body; the positioning base is provided with a horizontal sliding assembly for driving the clamping block to move horizontally and a vertical sliding assembly for driving the clamping block to move vertically.

[0012] The horizontal sliding assembly includes a pressure plate and a horizontal return spring for pulling the pressure plates closer together; the pressure plate is connected to a clamping block.

[0013] The vertical sliding assembly includes a second pressure plate and a vertical return spring for pushing the second pressure plate closer to the positioning base. The second pressure plate and the clamping block slide relative to each other.

[0014] The positioning base is equipped with a drive assembly that drives the movement of pressure plate one and pressure plate two.

[0015] By using the above technical solution, the sheet metal part is placed on the surface of the support surface, and the positioning flange will fit against the side of the sheet metal part, which can accurately position the sheet metal part and ensure that the subsequent clamping components can clamp the sheet metal part.

[0016] When the drive assembly drives the pressure plate to move, the pressure plate will move the clamping block away from the sheet metal part to be clamped in the horizontal direction. The vertical return spring can move the clamping block away from the sheet metal part to be clamped in the vertical direction, so that the clamping block moves away from the sheet metal part to be clamped, and the sheet metal part on the support surface can be taken out from the direction perpendicular to itself.

[0017] When the drive assembly drives the second pressure plate to move, the second pressure plate will drive the clamping block to move closer to the sheet metal part to be clamped in the vertical direction. The horizontal return spring can drive the clamping block to move away from the sheet metal part to be clamped in the horizontal direction, so that the clamping block moves closer to the sheet metal part to be clamped, and the clamping block can clamp and fix the sheet metal part on the support surface.

[0018] Based on the above technical solution, the present invention can be further improved as follows.

[0019] Furthermore, a receiving cavity is provided below the positioning base, and a set of clamping components is provided on each side of the positioning base. The lower end of the connecting rod is provided with a mounting base that extends into the receiving cavity.

[0020] The two mounting bases are provided with receiving holes on opposite sides, and the two ends of the horizontal return spring are respectively placed in the receiving holes.

[0021] Through the above technical solution, a clamping assembly is provided on each side of the positioning base to tighten the sheet metal parts on both sides, making them more stable when clamped; the receiving cavity isolates the external and internal components, which can prevent external objects from interfering with the internal components and also prevent mechanical damage.

[0022] The receiving hole protects and secures both ends of the horizontal return spring.

[0023] Furthermore, the mounting base is provided with a horizontal slider, and the pressure plate is provided with a horizontal slide rail that cooperates with the horizontal slider.

[0024] The above technical solution allows the horizontal slider and horizontal slide rail to move more stably.

[0025] Furthermore, the positioning flange has a guide slope on the side facing the sheet metal part, and the support surface has a tap clearance hole for the tap to extend into.

[0026] With the above technical solution, when the sheet metal part is placed on the surface of the support surface, the guide slope can guide the sheet metal part to easily cover the support surface. When tapping, the tap clearance hole can allow the tap to be inserted into the sheet metal part for tapping without damaging the support surface.

[0027] Furthermore, a clamping plate is fixedly connected to one side of the positioning base, and a clamping shaft is provided at the end of the clamping plate away from the positioning base.

[0028] Using the above technical solution, and in conjunction with the clamping shaft, this fixture can be mounted on the chuck. By rotating the chuck, the angle of this fixture can be adjusted so as to tap the holes on support plate one, support plate two, and support plate three.

[0029] Furthermore, a horizontal guide shaft is slidably disposed between the two mounting bases, and the horizontal guide shaft passes through a horizontal return spring.

[0030] With the above technical solution, the horizontal guide shaft is responsible for guiding the horizontal return spring during its stretching and resetting, ensuring that the horizontal return spring moves horizontally. The horizontal return spring can also play the same role when the two mounting bases move.

[0031] Furthermore, a vertical guide shaft is provided at one end of the pressure plate two, the vertical guide shaft passes through the vertical return spring, and a vertical guide sleeve is provided at one end of the vertical guide shaft.

[0032] Through the above technical solution, the vertical guide shaft is responsible for guiding the vertical return spring during compression and reset, ensuring that the vertical return spring moves in the vertical direction; the vertical guide sleeve can protect the vertical guide shaft and increase its service life.

[0033] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0034] 1. In the clamping state, the horizontal return spring can drive the clamping block to move towards the sheet metal part, and then cooperate with the drive cam to press the pressure plate two; when the pressure plate two is pressed, it can drive the clamping block to move towards the sheet metal part; thus, the sheet metal part to be tapped can be quickly clamped onto this fixture. With the cooperation of the clamping shaft, this fixture can be clamped onto the chuck. By rotating the chuck, the angle of this fixture can be adjusted so as to tap the holes on the support plate one, support plate two and support plate three; the clamping process is simple and the operation is convenient.

[0035] 2. When the tapping process is completed and the sheet metal part needs to be removed, simply turn the drive handle to make the drive cam push the pressure plate one to move away from each other; that is, the pressure plate one drives the clamping block to move away from the sheet metal part so as to remove the sheet metal part from the fixture.

[0048] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0050] Example:

[0051] refer to Figure 2 and Figure 3 A sheet metal part auxiliary tapping fixture includes a positioning component 2 for positioning the sheet metal part and a clamping component 3 for clamping the sheet metal part.

[0052] The positioning component 2 includes a positioning base 21 and a positioning flange 22. The positioning flange 22 is in contact with the side of the sheet metal part. The positioning base 21 is provided with a support surface that is in contact with the sheet metal part. The clamping component 3 includes a clamping block 31 and a connecting rod 32. The clamping block 31 extends toward the direction indicated by reference numeral 1 on the main body. The positioning base 21 is provided with a horizontal sliding component 4 that drives the clamping block 31 to move horizontally and a vertical sliding component 5 that drives the clamping block 31 to move vertically. It also includes a driving component 6.

[0053] When the sheet metal part is placed on the surface of the support surface, the positioning flange 22 will fit against the side of the sheet metal part, which can accurately position the sheet metal part and ensure that the clamping component 3 can clamp the sheet metal part. The driving component 6 can drive the horizontal sliding component 4 and the vertical sliding component 5 to clamp or release the sheet metal part on the support surface, ensuring the normal progress of subsequent tapping.

[0054] refer to Figure 3 and Figure 4 When the fixture is in the clamping state, rotating the drive handle 63 causes the drive cam 61 to press the two pressure plates 41 on both sides. The pressure plates 41 drive the connecting rod 32 to move the clamping block 31 in a horizontal direction away from the sheet metal part. At this time, the vertical return spring 54 starts to return from the compressed state. The vertical return spring 54 drives the pressure plate 51 and the mounting base 33 to move in a vertical direction closer to the drive cam 61. The mounting base 33 drives the connecting rod 32 to move the clamping block 31 in a vertical direction away from the sheet metal part. Finally, the clamping block 31 releases the sheet metal part on the support surface, and the fixture changes from the clamping state to the relaxed state.

[0055] refer to Figure 3 and Figure 4 When the fixture is in the relaxed state, rotating the drive handle 63 causes the drive cam 61 to press the pressure plate 51 at its bottom. The pressure plate 51 drives the connecting rod 32 to move the clamping block 31 towards the vertical direction closer to the sheet metal part. At this time, the horizontal return spring 45 starts to return from the stretched state. The horizontal return spring 45 drives the pressure plate 41 to move towards the horizontal direction closer to the drive cam 61. The pressure plate 41 drives the connecting rod 32 to move the clamping block 31 towards the horizontal direction closer to the sheet metal part. Finally, the clamping block 31 clamps the sheet metal part on the support surface, and the fixture changes from the relaxed state to the clamped state.

[0056] refer to Figure 2 Optionally, the drive handle 63 can be rotated manually, or the drive handle 63 can be replaced with a three-jaw chuck, which holds the drive rod 62 to rotate; preferably, the drive rod 62 is fitted with a connecting bearing 64, which can protect the drive rod 62 and make the drive rod 62 easier to rotate.

[0057] refer to Figure 3 The positioning flange 22 has a guide slope 23 on the side facing the sheet metal part. When the sheet metal part is placed on the surface of the support surface, the guide slope 23 can guide the sheet metal part to easily cover the support surface. The support surface has a tap relief hole 24 for the tap to be inserted. When tapping, the tap relief hole 24 allows the tap to be inserted into the sheet metal part for tapping without damaging the support surface.

[0058] refer to Figure 3 The clamping components 3 are provided on both sides of the positioning base 21 to clamp the sheet metal parts on both sides, making them more stable when clamped. A receiving cavity is provided below the positioning base 21. The receiving cavity isolates the external and internal components, which can prevent external objects from interfering with the internal components and also prevent mechanical damage.

[0059] refer to Figure 3 A horizontal slider 43 is provided on the mounting base 33, and a horizontal slide rail 42 is provided on the pressure plate 51 to slide and cooperate with the horizontal slider 43. The cooperation between the horizontal slider 43 and the horizontal slide rail 42 can make the mounting base 33 move more stably. A receiving hole is provided on the opposite side of the two mounting bases 33, and the two ends of the horizontal return spring 45 are respectively placed in the receiving hole. The receiving hole can protect and fix the two ends of the horizontal return spring 45.

[0060] refer to Figure 3A horizontal guide shaft 44 is slidably disposed between the two mounting bases 33. The horizontal guide shaft 44 passes through the horizontal return spring 45 and is responsible for guiding the horizontal return spring 45 to move horizontally. When the two mounting bases 33 move, the horizontal return spring 45 can also play the same role. A vertical guide shaft 52 is provided at one end of the pressure plate 51 and passes through the vertical return spring 54. When the vertical return spring 54 is compressed and reset, the vertical guide shaft 52 is responsible for guiding the vertical return spring 54 to move in the vertical direction. A vertical guide sleeve 53 is provided at one end of the vertical guide shaft 52. The vertical guide sleeve 53 can protect the vertical guide shaft 52 and increase the service life of the vertical guide shaft 52.

[0061] In a brief description of the specific operation, before tapping, rotate the drive handle 63 to relax the fixture and place the sheet metal part on the support surface along the positioning flange 22; rotate the drive handle 63 to drive the drive cam 61 to press the pressure plate 51 at its bottom. The pressure plate 51 drives the connecting rod 32 to move the clamping block 31 in the vertical direction closer to the sheet metal part. At this time, the horizontal return spring 45 starts to return from the stretched state. The horizontal return spring 45 drives the pressure plate 41 to move in the horizontal direction closer to the drive cam 61. The pressure plate 41 drives the connecting rod 32 to move the clamping block 31 in the horizontal direction closer to the sheet metal part, and finally the clamping block 31 clamps the sheet metal part on the support surface.

[0062] After tapping is completed, rotating the drive handle 63 causes the drive cam 61 to press the two bearing plates 41. The bearing plates 41 drive the connecting rod 32 to move the clamping block 31 in a horizontal direction away from the sheet metal part. At this time, the vertical return spring 54 starts to return from the compressed state. The vertical return spring 54 drives the bearing plate 51 and the mounting base 33 to move in a vertical direction closer to the drive cam 61. The mounting base 33 drives the connecting rod 32 to move the clamping block 31 in a vertical direction away from the sheet metal part. Finally, the clamping block 31 releases the sheet metal part on the support surface. At this time, the sheet metal part on the support surface can be removed manually or mechanically from the direction perpendicular to itself.

[0063] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
