Description

Technical Field

[0001] This utility model relates to the field of machining fixture technology, specifically a clamping device for machining an integrated reducer housing. Background Technology

[0002] An integrated reducer is a transmission device that integrates a motor and a reducer into one unit through a compact design. Compared with a separate reducer, an integrated reducer shortens the transmission link, reduces energy loss, and improves efficiency by about 15%-20%. By optimizing gear meshing design and material strength, it can withstand higher loads and extend service life. The integrated damping block and precision gear machining technology effectively reduce operating noise and vibration amplitude. However, when processing the housing of an integrated reducer, it is necessary to perform operations such as grooving and drilling on its surface. Therefore, a clamping device is required to clamp the housing material of the integrated reducer.

[0003] When machining existing integrated reducer housings, the surface of the housing is not a complete plane, which means that the housing lacks sufficiently stable limiting when clamped and fixed on the side. This can lead to displacement and damage of the housing during machining. In view of this, we propose a clamping device for machining integrated reducer housings. Utility Model Content

[0004] The purpose of this invention is to provide a clamping device for machining an integrated reducer housing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a clamping device for processing an integrated reducer housing, comprising a base, an electric push rod fixedly connected to the side wall of the base, a clamping plate fixedly connected to the end of the electric push rod, and a limit component provided inside the clamping plate;

[0006] The limiting component includes a sleeve rod, which is slidably mounted on the inner wall of the clamping plate. A pull rod is slidably mounted on the inner wall of the sleeve rod. A connecting spring is fixedly connected between the bottom end of the pull rod and the inner wall of the sleeve rod. A lifting plate is fixedly mounted on the top end of the pull rod. A handle is fixedly mounted through the inner wall of the lifting plate. An abutment plate is slidably mounted on the inner wall of the clamping plate away from the electric push rod. A pressing spring is fixedly connected between the abutment plate and the inner wall of the clamping plate. A slot is provided on the side wall of the abutment plate.

[0007] Preferably, a deformation cavity is formed on the inner wall of the clamping plate on the side away from the electric push rod, and multiple sets of abutment plates are arranged in a linear array in the deformation cavity to better adapt to the integrated reducer housing with different shapes.

[0008] Preferably, the sleeve rod is hollow inside, and the handle is U-shaped, with the bottom end of the handle abutting the upper surface of the clamp plate. This prevents the pull rod from moving completely downwards to its lowest point during assembly, thus avoiding interference with the sleeve rod's installation and positioning in the slot.

[0009] Preferably, the width of the sleeve is adapted to the slot, and the number of sleeves and slots is set in multiple sets. The multiple sets of sleeves and slots are mirror images of each other on the left and right sides of the vertical central axis of the clamping plate, thereby ensuring the limiting effect of the abutment plate on the clamping plate.

[0010] Preferably, the bottom of the abutment plate is provided with an anti-slip component, the anti-slip component includes a contact groove, the contact groove is formed on the lower surface of the abutment plate, an arc-shaped strip is fixedly installed on the top inner surface of the contact groove, an elastic telescopic rod is fixedly connected to the side wall at the center of the arc-shaped strip, and an arc-shaped sliding groove is formed on the lower surface of the arc-shaped strip.

[0011] Preferably, the arc-shaped belt is made of rubber, and both ends of the arc-shaped belt are fixedly connected to the contact groove, while the center of the arc-shaped belt is in close contact with the inner surface of the contact groove.

[0012] Preferably, the number of the arc-shaped bands is set to two sets, and the two sets of arc-shaped bands are mirror images of each other at both ends of the elastic telescopic rod, and the arc-shaped bands are arranged in a C-shape.

[0013] Compared with the prior art, this utility model provides a clamping device for machining an integrated reducer housing, which has the following advantages:

[0014] 1. This clamping device for machining an integrated reducer housing, by setting a limiting component and a clamping spring, allows several abutment plates in the deformation cavity to better fit the side surface of the integrated reducer housing. Then, the handle, pull rod, and sleeve rod are pressed down along the inner wall of the clamping plate, so that the sleeve rod enters the slot. The setting of multiple sleeve rods ensures that each abutment plate is limited by the slot and maintains good stability, thereby ensuring the stability of the integrated reducer housing during machining and improving the performance of the device.

[0015] 2. The clamping device used for machining the housing of an integrated reducer is equipped with anti-slip components. When the abutment plate contacts the side surface of the integrated reducer housing, the contact groove is exposed on the surface of the integrated reducer housing. At this time, under the elastic force of the elastic telescopic rod, the C-shaped arc strip of rubber material subjected to friction can produce a certain deformation, thereby providing sufficient friction on the surface of the integrated reducer housing, enabling it to maintain higher stability and ensuring its machining quality.

Detailed Implementation

[0023] like Figures 1-6 As shown, this utility model provides a technical solution: a clamping device for processing an integrated reducer housing, including a base 1, an electric push rod 2 fixedly connected to the side wall of the base 1, a clamping plate 3 fixedly connected to the end of the electric push rod 2, a processing table 4 fixedly connected to the bottom of the base 1, and a limiting component 5 provided inside the clamping plate 3. The limiting component 5 includes a sleeve rod 54, a pull rod 53, a connecting spring 55, a lifting plate 52, a handle 51, an abutment plate 56, a pressing spring 57, and a slot 58.

[0024] In one embodiment of this utility model, the sleeve rod 54 is slidably installed on the inner wall of the clamping plate 3, and a pull rod 53 is slidably installed on the inner wall of the sleeve rod 54. A connecting spring 55 is fixedly connected between the bottom end face of the pull rod 53 and the inner wall of the sleeve rod 54. A lifting plate 52 is fixedly installed at the top end of the pull rod 53. A handle 51 is fixedly installed through the inner wall of the lifting plate 52. An abutment plate 56 is slidably installed on the inner wall of the clamping plate 3 away from the electric push rod 2. A pressing spring 57 is fixedly connected between the abutment plate 56 and the inner wall of the clamping plate 3. A slot 58 is provided on the side wall of the abutment plate 56.

[0025] Furthermore, two sets of bases 1 are provided, and the two sets of bases 1 are symmetrically arranged about the vertical central axis of the processing table 4. This allows them to work with the two sets of clamping plates 3 to clamp and fix the integrated reducer housing on the processing table 4. At the same time, a deformation cavity is formed on the inner wall of the clamping plate 3 on the side away from the electric push rod 2. Multiple sets of abutment plates 56 are provided, and the multiple sets of abutment plates 56 are arranged in a linear array in the deformation cavity to better adapt to integrated reducer housings of different shapes. In addition, the sleeve rod 54 is hollow inside. Furthermore, the handle 51 is U-shaped, and the bottom surface of the handle 51 is attached to the upper surface of the clamping plate 3. Therefore, during assembly, the pull rod 53 will not move completely downward to the lowest point, thereby interfering with the installation and positioning of the sleeve rod 54 in the slot 58. Specifically, the width of the sleeve rod 54 is adapted to the slot 58, and there are multiple sets of sleeve rods 54 and slots 58. Multiple sets of sleeve rods 54 and slots 58 are mirror images of each other on the left and right sides of the vertical central axis of the clamping plate 3, thereby ensuring the limiting effect of the abutment plate 56 on the clamping plate 3.

[0026] In addition, several rubber protrusions are provided on the surface of the abutment plate 56 away from the clamping plate 3 to increase the static friction coefficient when the abutment plate 56 contacts the side of the integrated reducer housing, so that the abutment plate 56 cooperates with the clamping plate 3 to stably clamp the integrated reducer housing.

[0027] Please refer to the attached instruction manual. Figure 6 The bottom of the abutment plate 56 is provided with an anti-slip component 6. The anti-slip component 6 includes a contact groove 61. The contact groove 61 is opened on the lower surface of the abutment plate 56. An arc-shaped belt 62 is fixedly installed on the top inner surface of the contact groove 61. An elastic telescopic rod 63 is fixedly connected to the side wall at the center of the arc-shaped belt 62. An arc-shaped groove 64 is opened on the lower surface of the arc-shaped belt 62.

[0028] In this embodiment of the present invention, the arc-shaped belt 62 is made of rubber belt, and both ends of the arc-shaped belt 62 are fixedly connected to the contact groove 61, while the center of the arc-shaped belt 62 is in close contact with the inner surface of the contact groove 61. At the same time, there are two sets of arc-shaped belts 62, and the two sets of arc-shaped belts 62 are mirror images of each other at both ends of the elastic telescopic rod 63. The arc-shaped belt 62 is C-shaped. When the abutment plate 56 contacts the side surface of the integrated reducer housing, the contact groove 61 is exposed on the surface of the integrated reducer housing. At this time, under the elastic force of the elastic telescopic rod 63, the C-shaped arc-shaped belt 62 of rubber material subjected to friction can produce a certain deformation, thereby providing sufficient friction on the surface of the integrated reducer housing, so as to maintain higher stability and ensure its processing quality.

[0029] In this invention, during use, the integrated reducer housing is placed on the processing table 4. At this time, the electric push rod 2 is activated so that the clamping plates 3 clamp the integrated reducer housing on the left and right sides of the processing table 4. As the clamping plates 3 approach, the setting of the clamping spring 57 allows the several abutment plates 56 in the deformation cavity to better fit the side surface of the integrated reducer housing. Then, the handle 51, the pull rod 53, and the sleeve rod 54 are pressed down along the inner wall of the clamping plate 3, so that the sleeve rod 54 enters the slot 58. The setting of multiple sets of sleeve rods 54 can ensure that each abutment plate 56 can be limited by the slot 58 to maintain good stability, thereby ensuring the stability of the integrated reducer housing during processing and improving the use effect of the device.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
