Description

Technical Field

[0001] The utility model relates to the technical field of bearing seat clamp devices, in particular to a bearing seat processing clamp. Background Art

[0002] The transmission parts on the machine tool are generally supported on the box body by the shaft. In order to reduce the friction between the shaft and the box body, bearings are often required between the shaft and the box body. The bearings are supported in the bearing seats. Therefore, the bearing seats are a type of parts that are extremely widely used in machine tools. The traditional processing methods of bearing seats are mostly single-piece production. Each workpiece must be re-clamped for processing, which is very inefficient and has high labor intensity for workers. It cannot meet the large-scale demand for bearing seat products in the industry. Therefore, it is necessary to design a clamping device with simple structure, same clamping force, reliable and convenient clamping, high processing efficiency, strong adaptability of the fixture, small number of pressure rods, large clamping force, low labor intensity for workers, and high clamping efficiency.

[0003] For example, a bearing seat processing fixture with the announcement number CN106181498A includes a base plate, a clamping device, and an air pump. The base plate is a rectangular thin plate, the clamping device is arranged on the upper surface of the base plate, and the air pump is arranged at the right front corner of the upper surface of the base plate. It also includes a handle, an air pipe, a pressure rod, a baffle, a positioning block, an air storage cylinder, a piston shaft, a chuck, and a cylindrical pin. The baffle is arranged on the upper surface of the base plate opposite to the clamping device, the positioning block is arranged on the upper surface of the base plate between the clamping device and the baffle, the pressure rod is fixed on the upper surface of the base plate in the middle of the front and rear direction, the air pump and the clamping device are connected by the air pipe, and the switch of the air pump is operated by the handle.

[0004] The above-mentioned device adopts a bearing seat processing fixture designed by combining multiple components such as a base plate. It has a simple structure and is equipped with eight components in total. It is controlled by the same air pump. When clamping the workpiece, it can be automatically adjusted. The fixture has strong adaptability. There are two baffles in total, which are symmetrically arranged relative to the front and rear symmetry lines of the base plate. When the workpiece is clamped, one end is clamped by a chuck and the other end is blocked by the baffle to achieve clamping. The length of the pressure rod exceeds the distance between the front and rear baffles. Each pressure rod clamps a workpiece at both ends. The number of pressure rods is small, and the chuck is clamped pneumatically, with a large clamping force, low labor intensity for workers, and high clamping efficiency. However, since the designs of most bearing seats nowadays are relatively similar, the placement of eight clamping devices is somewhat redundant, and often only a few clamping devices are needed to fix the bearing seat in the horizontal and vertical directions to complete the clamping operation. Utility Model Content

[0005] The purpose of the utility model is to provide a bearing seat processing fixture to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bearing seat processing fixture, including a main box body, auxiliary plates are arranged on both sides of the inner surface of the main box body, and screws are arranged on the auxiliary plates to fix them, and a transmission device is arranged on the surface of the main box body corresponding to the position of the auxiliary plates, a driving device is arranged on the back side of the main box body, and a telescopic column is arranged at the corresponding position of the inner surface, and a clamping plate is arranged at the front end of the telescopic column, a displacement end face is arranged on the back side of the clamping plate, a clamping arm is arranged on the outer surface of the clamping plate, and a main body fixture is arranged on the upper surface of the auxiliary plate, and an inclined port is arranged on the inner lower surface of the main box body.

[0007] Preferably, a pushing device is arranged on the surface of the auxiliary plate, and a plurality of outer pushing rings are arranged in the middle of the pushing device, and a pressing layer is arranged on the outer layer of the pushing device.

[0008] Preferably, longitudinal sliding teeth are arranged on the surface of the auxiliary plate to pass through the pushing device.

[0009] Preferably, the front end of the outer push ring is connected to the vacant plate, and a rotating disk is arranged at the upper end of the vacant plate, and a rotating column is arranged at the upper end of the rotating disk.

[0010] Preferably, a main body clamp is arranged on the surface of the rotating column, and clamping ends are arranged at both ends of the rotating column, and a buffer surface layer is arranged on the surface of the rotating disk.

[0011] Preferably, an inclined end surface is arranged on the inner surface of the lower end of the main box body, and an inclined port is arranged at a corresponding position of the bottom of the inclined end surface.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. Compared with other bearing seat processing fixtures, this device is designed with processing fixtures on both sides according to most models of bearing seats. When the bearing seat is effectively clamped, the fixtures on both sides are used to fix it horizontally, while the auxiliary fixing chuck arranged longitudinally can effectively fix it longitudinally. The effect of fixing both sides at the same time makes it possible to clamp the bearing seat stably, which is better than other clamping devices with fewer but better effects.

[0014] 2. In addition, the device is also equipped with a sloped surface at the lower end of the fixture. When processing the bearing seat, a large amount of debris will inevitably be generated. The sloped surface at the lower end can facilitate the recycling of debris and other garbage, reduce the subsequent processing operations of the device by the processing personnel, and save time.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 4 , the utility model provides a technical solution:

[0022] Figure 1 This is a front overview of the device. The main body is a main box body 3. Auxiliary plates 5 are arranged on both sides of the inner surface of the main box body 3, and screws 4 are arranged on the auxiliary plates 5 to fix them. The placement of the auxiliary plates 5 provides the required carrier for the subsequent placement of the longitudinal sliding teeth 12. An inclined end surface is arranged on the inner surface of the lower end of the main box body 3, and an inclined port 6 is arranged at the corresponding position of the bottom of the inclined end surface. Since the processing of the bearing seat will generate a large amount of mechanical debris such as debris, the combination of the inclined end surface and the inclined port 6 makes the subsequent cleaning and processing work after processing relatively easy and simple;

[0023] Figure 2 The top view of the device is shown in FIG. 1 . The main body is a main box body 3. A transmission device 7 is arranged on the surface of the main box body 3 at a position corresponding to the auxiliary plate 5. A driving device 9 is arranged on the back side of the main box body 3. The driving device 9 provides the required power for the whole. Because the installation positions of the components are different, the installation of the transmission device 7 is used to provide power for the driving parts in other different directions. A telescopic column 8 is arranged at a corresponding position on the inner surface. A clamping plate 1 is arranged at the front end of the telescopic column 8. A displacement end surface 10 is arranged on the back side of the clamping plate 1. A clamping arm 2 is arranged on the outer surface of the clamping plate 1. The displacement end surface 10 controls the movement of the clamping arm 2 to effectively clamp and fix one side of the bearing seat.

[0024] Figure 3This is an overview of the left side of the device. The main body is an auxiliary plate 5. A pushing device 13 is arranged on the surface of the auxiliary plate 5, that is, a device with a drum push column arranged in the middle, and a plurality of outer push rings 11 are arranged in the middle of the pushing device 13. The arrangement of the push ring enables the middle section to perform a forward convex movement operation, providing a lateral movement effect for the middle main body clamp 16, which can adapt to the clamping of bearing seats of different sizes. At the same time, a pressure layer 14 is arranged on the outer layer of the pushing device 13. Since the outer push ring 11 is embedded in the middle of the pushing device 13, the pressure layer 14 has a major fixing effect on the outer push ring 11. Such a design is more convenient for the subsequent disassembly and repair of the outer push ring 11. A longitudinal sliding tooth 12 is arranged on the surface of the auxiliary plate 5 to pass through the pushing device 13, providing a longitudinal movement effect for the device, so as to better cooperate with the clamping plate 1.

[0025] Figure 4 This is an overview of the right side of the device. The main body is an outer push ring 11. The front end of the outer push ring 11 is connected to an empty plate 15 for placing a carrier, and a rotating disk 17 is set at the upper end of the empty plate 15 to provide a rotation effect for the front end part. At the same time, a rotating column 19 is set at the upper end of the rotating disk 17, and a main body clamp 16 is set on the surface of the rotating column 19, and a locking end 20 is set at both ends of the rotating column 19. The placement of the rotating column 19 allows the main body clamp 16 to swing within a range, thereby increasing the adaptability of the device, and the placement of the locking end 20 allows the rotating column 19 to rotate freely inside without falling. At the same time, a buffer surface layer 18 is set on the surface of the rotating disk 17. The placement of the buffer surface layer 18 reduces damage to the main body clamp 16 when the swing amplitude of the main body clamp 16 contacts the rotating disk 17 up and down.

[0026] During actual use, first start the driving device 9 and the transmission devices 7 on both sides, and use the outer push ring 11 in the middle of the pushing device 13 on both sides to push outward, so that the middle main body clamp 16 is close to the bearing seat, adjust the swing amplitude and angle of the main body clamp 16, and fix it in the middle part. At this time, move the pushing device 13 and set its height to be flush with the height of the clamping plate 1, move the telescopic column 8, and use the clamping arm 2 on the clamping plate 1 to effectively fix the other side of the bearing seat. The three-party fixing clamp ensures the stability of the bearing seat itself, and finally processing and subsequent debris disposal can be carried out.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
