Abstract
Description
Technical Field
[0001] This utility model belongs to the field of parts machining technology, and in particular relates to a parts clamping device with sawtooth engagement. Background Technology
[0002] In the machining of parts, it is often necessary to clamp and position the parts using a clamping device before machining. This requires the clamping device to ensure reliable clamping of the parts. Currently, the clamping method generally uses a strip clamping plate. After the strip clamping plate is locked in the middle with bolts, one end clamps the part, and the other end clamps a shim block. The shim block is required to be the same height as the part. This clamping method has low stability, and the strip clamping plate itself is prone to vibration and displacement, which affects the machining quality of the parts. Furthermore, shims of appropriate height must be selected for parts of different heights, making the operation cumbersome. Utility Model Content
[0003] The main objective of this invention is to provide a toothed meshing component clamping device, which can effectively solve the problems in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A toothed meshing component clamping device, comprising:
[0006] Workbench;
[0007] The component is located on one side of the top surface of the worktable;
[0008] A support is fixed to the other side of the top surface of the workbench, and the side of the support facing the component has a first serrated bevel.
[0009] A long pressure plate has a groove at the bottom of one end, in which a pressure head can be detachably installed for pressing parts. The other end of the long pressure plate has a second serrated bevel, which can mesh with the first serrated bevel. A waist groove hole is opened in the middle of the long pressure plate.
[0010] A screw rod is inserted into the waist groove hole. The bottom of the screw rod is fixedly connected to the worktable, and a locking nut is connected to the top of the screw rod for locking the long pressure plate.
[0011] Preferably, the support is a triangular prism-like structure, with one side serving as the bottom and contacting the workbench, and the other side being configured as the first serrated bevel, the back of which is hollowed out.
[0012] Preferably, the hollowed-out portion has a bottom plane and an inclined plane opposite to the first sawtooth inclined plane, and the bottom plane has at least two mounting grooves for fixing the support to the workbench by bolts.
[0013] Preferably, the long pressure plate has at least two bolt holes at the upper part of the groove for fixing the pressure head with bolts.
[0014] Preferably, the end of the long pressure plate with the second serrated bevel has a structure in which the width gradually increases from top to bottom.
[0015] Preferably, the lower end of the screw is threaded to the workbench, the top of the screw has a notch, and the lower part of the screw is connected to an anti-loosening nut.
[0016] This utility model provides a toothed meshing component clamping device, which has the following beneficial effects:
[0017] 1. Because the second serrated inclined surface of the long pressure plate meshes with the first serrated inclined surface of the support, the two are in close contact, which can limit the long pressure plate and effectively prevent the long pressure plate from shifting due to vibration, thereby ensuring the stability of the parts processing and improving the processing quality.
[0018] 2. The long pressure plate of this device has a waist groove hole in the middle, so that the position and height of the long pressure plate can be flexibly adjusted when dealing with parts of different heights. The second serrated inclined surface of the long pressure plate can mesh with the first serrated inclined surface at different heights, without the need to replace the support, making the operation simple and convenient.
[0019] 3. The slot of the long pressure plate of this device is equipped with a detachable pressure head, which can be flexibly replaced with different pressure heads. The pressure head and the long pressure plate are designed separately, which makes it easier to adapt to the pressure and positioning requirements of different parts when using the device for actual pressing and positioning.

[0028] Example
[0029] Reference Figure 1-3 A toothed meshing component clamping device, comprising:
[0030] Workbench 1;
[0031] Component 2 is located on one side of the top surface of the workbench 1;
[0032] Support 3 is fixed on the other side of the top surface of the workbench 1, and the side of support 3 facing component 2 has a first serrated inclined surface 31.
[0033] The long pressure plate 4 has a groove 41 at the bottom of one end, in which a pressure head 6 is detachably installed for pressing the component 2. The other end of the long pressure plate 4 has a second serrated inclined surface 42, which can mesh with the first serrated inclined surface 31. The long pressure plate 4 has a waist groove hole 43 in the middle.
[0034] The screw 5 is inserted into the waist groove hole 43. The bottom of the screw 5 is fixedly connected to the workbench 1, and the top of the screw 5 is connected to a locking nut 7 for locking the long pressure plate 4.
[0035] When in use, the long pressure plate 4 is placed horizontally, with the second sawtooth inclined surface 42 at one end engaging with the first sawtooth inclined surface 31 of the support 3, and the pressure head 6 at the other end placed on the component 2. The long pressure plate 4 is then locked by tightening the locking nut 7, thereby pressing and positioning the component 2 through the pressure head 6.
[0036] Because the second serrated inclined surface 42 of the long pressure plate 4 meshes with the first serrated inclined surface 31 of the support 3, the two are in close contact, which can limit the long pressure plate 4 and effectively prevent the long pressure plate 4 from shifting due to vibration, thereby ensuring the stability of the processing of the parts 2 and improving the processing quality.
[0037] The long pressure plate 4 of this device has a waist groove hole 43 in the middle, so that the position and height of the long pressure plate 4 can be flexibly adjusted when dealing with parts 2 of different heights. The second serrated inclined surface 42 of the long pressure plate 4 can mesh with the parts of the first serrated inclined surface 31 at different heights, without the need to replace the support 3, making the operation simple and convenient.
[0038] Furthermore, the slot 41 of the long pressure plate 4 of this device is equipped with a detachable pressure head 6, which can be flexibly replaced with different pressure heads 6. For example, some parts 2 are made of aluminum, which is relatively soft. Using a small-sized pressure head 6 to press them can easily damage the parts 2. In this case, replacing it with a pressure head 6 with a larger contact area can easily and effectively prevent damage. Some parts 2 are made of solid material, but have a large machining allowance, which will cause a lot of vibration during processing. In this case, for processing stability, a pressure head 6 with a toothed contact surface can be selected. This can indirectly increase the "gripping force" of the long pressure plate 4. The pressure head 6 and the long pressure plate 4 are designed separately, which makes it easier to adapt to the clamping and positioning requirements of different parts 2 when using the device for clamping and positioning.
[0039] As a preferred embodiment, the support 3 is a triangular prism structure, with one side serving as the bottom and contacting the workbench 1, and the other side being the first serrated inclined surface 31. The included angle between the two sides is 60°. The back of the first serrated inclined surface 31 is hollowed out, which is mainly to reduce the overall weight of the device and also to eliminate unnecessary volume.
[0040] The first sawtooth bevel 31 can be cut out by wire cutting or processed by a combination of stamping and milling machine cutting.
[0041] As a preferred embodiment, the hollow portion forms a bottom plane 32 and an inclined plane 33 opposite to the first sawtooth inclined plane 31. The angle between the bottom plane 32 and the inclined plane 33 is 80°. The bottom plane 32 has at least two mounting grooves 34 for fixing the support 3 to the workbench 1 with bolts.
[0042] As a preferred embodiment, the long pressure plate 4 has at least two bolt holes 44 at the upper part of the slot 41 for fixing the pressure head 6 with bolts, thereby achieving the detachable installation of the pressure head 6 in a simple way.
[0043] As a preferred embodiment, the long pressure plate 4 has a structure in which the width of one end of the second serrated inclined surface 42 gradually increases, which can increase the area of the second serrated inclined surface 42 and the strength of that end.
[0044] In a preferred embodiment, the lower end of the screw 5 is threaded to the workbench 1, and a notch is provided on the top of the screw 5 to facilitate screwing. An anti-loosening nut 8 is connected to the lower part of the screw 5. After tightening the anti-loosening nut 8, it is made to make close contact with the workbench 1 to prevent the screw 5 from loosening.
[0045] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
