Description

Technical Field

[0001] This utility model relates to the field of positioning tooling technology, specifically to a positioning and pressing tooling. Background Technology

[0002] Positioning and pressing fixtures are tools used in machining and assembly processes, mainly for positioning and pressing workpieces. Through precise positioning and clamping functions, they ensure the stability and accuracy of workpieces during machining or assembly.

[0003] A positioning and pressing fixture, authorized by publication number CN217045316U, includes: a pressing force plate for supporting a side cover, the pressing force plate having a passage opening; a skeleton oil seal support block located below the passage opening of the pressing force plate for supporting the skeleton oil seal; a skeleton oil seal positioning component located on the skeleton oil seal support block and inserted into the skeleton oil seal for radial positioning of the skeleton oil seal; and a first guide mechanism connected to the pressing force plate, allowing the pressing force plate to move towards the skeleton oil seal positioning component via the first guide mechanism. The advantage of this utility model is that it can simultaneously perform the pressing of the high-pressure supply pump side cover and bearing outer ring, as well as the pressing of the side cover and skeleton oil seal, in a single pressing operation. It achieves the functions of two separate fixtures in a single setup, reducing fixture costs, floor space, and personnel movement time, thus improving production efficiency.

[0004] The existing technology has the following shortcomings: During use, the existing positioning and pressing fixture is affected by the shape and size of the workpiece. The pressure plate of the fixture cannot easily press and fix the top surface of the workpiece, which makes the workpiece prone to displacement due to insecure fixing during the processing. At the same time, the workpiece is prone to damage during the pressing process, which affects the efficiency and quality of pressing the workpiece. Utility Model Content

[0005] The purpose of this utility model is to provide a positioning and pressing fixture. By setting up the X-axis and Y-axis adjustable sliding plates, the position of the bottom pressure plate of the Y-axis adjustable sliding plate can be easily adjusted. The operation of the motion cylinder enables the pressure plate to stably position and press the workpiece. At the same time, the clamping mechanism can clamp the workpiece, so that the workpiece remains stable during the processing, thereby solving the above-mentioned shortcomings in the technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning and pressing fixture, including a fixing mechanism, and further comprising:

[0007] The pressing mechanism is located on the top inner side of the fixing mechanism and is used to position and press the workpiece.

[0008] The clamping mechanism is located at the bottom inside the fixing mechanism and is used to clamp and fix the workpiece.

[0009] The pressing mechanism includes a pressing plate, which is located on the top inner side of the fixing mechanism. A motion cylinder is provided on the top of the pressing plate. A universal ball is rotatably installed at the middle position of the bottom of the pressing plate. A reset plate is rotatably installed at the bottom of the universal ball. An X-axis adjustable sliding plate is movably installed at the bottom of the reset plate. A Y-axis adjustable sliding plate is movably installed at the bottom of the X-axis adjustable sliding plate. Guide columns are fixedly installed on the inner walls of the four corners of the Y-axis adjustable sliding plate.

[0010] Preferably, the fixing mechanism includes a base plate, with movable grooves on both outer walls of the base plate, support plates fixedly installed on both outer walls of the base plate, and top plates fixedly installed on the top of the two support plates.

[0011] Preferably, the top of the top plate is fixedly connected to the moving cylinder, the piston rod of the moving cylinder passes through the inner wall of the top plate and is fixedly connected to the top of the pressing plate, and guide rods are fixedly installed at both ends of the top of the pressing plate.

[0012] Preferably, the top of the outer wall of the two guide rods is movably connected to the inner wall of both ends of the top plate, the bottom of the reset plate is provided with a T-shaped groove for sliding the X-axis adjustable slide plate, and the bottom of the X-axis adjustable slide plate is provided with a T-shaped groove for sliding the Y-axis adjustable slide plate.

[0013] Preferably, a fixed shaft penetrating the inner wall of the press plate is fixedly installed at each of the four corners of the top of the reset plate, and a reset spring movably sleeved on the outside of the fixed shaft is fixedly installed between the fixed shaft and the top of the press plate.

[0014] Preferably, the clamping mechanism includes two clamping plates, which are respectively disposed at the top ends of the base plate. A movable rack disposed on the inner wall of the movable groove on the same side is fixedly installed on one outer wall of each of the two clamping plates, and a slider movably connected to the inner wall of the movable groove on the same side is fixedly installed on the other outer wall of each of the two clamping plates.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] Guided by the directional guide column and the automatic rotation angle of the universal ball, the X-axis adjustable slide slides along the T-shaped groove at the bottom of the reset plate, allowing the pressure plate to move along the X-axis. The Y-axis adjustable slide slides along the T-shaped groove at the bottom of the X-axis adjustable slide, allowing the pressure plate to move along the Y-axis. This allows for convenient adjustment of the pressure plate's position. At the same time, the height of the pressure plate can be adjusted by the operation of the motion cylinder, enabling the pressure plate to easily press and fix irregularly shaped workpieces, thus keeping the workpiece stable during processing and ensuring the stable operation of the press-fitting process.

[0018] The distance between the two clamping plates can be adjusted by the meshing action between the rotating gear and the movable rack through the operation of the servo motor. This allows the two clamping plates to clamp and fix workpieces of different sizes. At the same time, the movable groove can limit the movement of two adjacent sliders, so that the clamping plates remain stable during the adjustment process. Attached Figure Description

[0029] This utility model provides, for example Figure 1 The positioning and pressing fixture shown includes a fixing mechanism 1, and further includes:

[0030] The pressing mechanism 2 is located on the top inner side of the fixing mechanism 1 and is used to position and press the workpiece.

[0031] The clamping mechanism 3 is located at the bottom inside the fixing mechanism 1 and is used to clamp and fix the workpiece.

[0032] To facilitate the positioning and pressing of machined parts, such as Figure 1-2 and Figure 4 As shown, the pressing mechanism 2 includes a pressing plate 201, which is located on the top inner side of the fixed mechanism 1. A motion cylinder 202 is provided on the top of the pressing plate 201. A universal ball 203 is rotatably installed at the middle position of the bottom of the pressing plate 201. A reset plate 204 is rotatably installed at the bottom of the universal ball 203. An X-axis adjusting slide plate 206 is movably installed at the bottom of the reset plate 204. A Y-axis adjusting slide plate 207 is movably installed at the bottom of the X-axis adjusting slide plate 206. Guide columns 208 are fixedly installed on the inner walls of the four corners of the Y-axis adjusting slide plate 207. Through the automatic rotation angle of the universal ball 203 and the guiding effect of the guide columns 208, the horizontal position of the pressing plate can be adjusted by the X-axis adjusting slide plate 206 and the Y-axis adjusting slide plate 207, thereby enabling the pressing plate to perform positioning and pressing operations on workpieces of different sizes.

[0033] To facilitate the installation and fixing of the pressing mechanism 2 and the clamping mechanism 3, such as Figure 1-3 As shown, the fixing mechanism 1 includes a base plate 101. Movable grooves 102 are provided on both outer walls of the base plate 101. Support plates 103 are fixedly installed on both outer walls of the base plate 101. Top plates 104 are fixedly installed on the top of the two support plates 103. The pressing mechanism 2 can be installed and fixed through the top plate 104, and the clamping mechanism 3 can be installed and fixed through the base plate 101, so that the pressing mechanism 2 and the clamping mechanism 3 remain stable during operation.

[0034] To allow for easy adjustment of the pressure plate position, such as Figure 1-4As shown, the top of the top plate 104 is fixedly connected to the motion cylinder 202. The piston rod of the motion cylinder 202 passes through the inner wall of the top plate 104 and is fixedly connected to the top of the pressure plate 201. Guide rods 209 are fixedly installed at both ends of the top of the pressure plate 201. The top of the outer wall of the two guide rods 209 is movably connected to the inner walls at both ends of the top plate 104. The bottom of the reset plate 204 has a T-shaped groove for the sliding of the X-axis adjustment slide plate 206. The bottom of the X-axis adjustment slide plate 206 has a T-shaped groove for the sliding of the Y-axis adjustment slide plate 207. The X-axis adjustment slide plate 206 moves along the T-shaped groove at the bottom of the reset plate 204, and the Y-axis adjustment slide plate 207 moves along the T-shaped groove at the bottom of the X-axis adjustment slide plate 206. This allows the position of the pressure plate to be adjusted. The operation of the motion cylinder 202 can adjust the height of the pressure plate. At the same time, the guide rods 209 can limit the movement of the pressure plate in the vertical direction, so that the pressure plate can stably position and press the workpiece.

[0035] To allow the pressure plate to be easily reset, such as Figure 2 and Figure 4 As shown, fixed shafts that penetrate the inner wall of the pressure plate 201 are fixedly installed at the four corners of the top of the reset plate 204. A reset spring 205 that is movably sleeved on the outside of the fixed shaft is fixedly installed between the fixed shaft and the top of the pressure plate 201. The reset spring 205 can drive the reset plate 204 to automatically reset.

[0036] To facilitate the clamping and fixing of the workpiece, such as Figure 1-3 and Figure 5 As shown, the clamping mechanism 3 includes two clamping plates 301, which are respectively disposed at the top ends of the base plate 101. Movable racks 302, which are disposed on the inner wall of the same-side movable groove 102, are fixedly installed on one outer wall of each clamping plate 301. Slider blocks 303, which are movably connected to the inner wall of the same-side movable groove 102, are fixedly installed on the other outer wall of each clamping plate 301. A servo motor 304 is fixedly installed on one outer wall of the base plate 101. A rotating gear 305 is fixedly sleeved on the outer side of the output shaft of the servo motor 304. The rotating gear 305 meshes with the two movable racks 302. The servo motor 304, through the meshing action between the rotating gear 305 and the two movable racks 302, can adjust the distance between the two clamping plates 301. Simultaneously, the movable groove 102 can limit the movement of the movable racks 302 and the sliders 303, enabling the clamping plates 301 to stably clamp and fix workpieces of different sizes.

[0037] When positioning and pressing the workpiece, the workpiece is placed on top of the base plate 101. Then, the servo motor 304, through the meshing action between the rotating gear 305 and the two movable racks 302, can drive the two clamping plates 301 to move relative to or away from each other, so that the two clamping plates 301 can clamp and fix the workpiece. At the same time, the two movable slots 102 can limit the movement of adjacent movable racks 302 and sliders 303, so that the clamping plates 301 remain stable during movement. Meanwhile, the pressure plate moves along the T-shaped groove at the bottom of the reset plate 204 via the X-axis adjusting slide plate 206, and the Y-axis adjusting slide plate 207 moves along the T-shaped groove at the bottom of the X-axis adjusting slide plate 206, thereby facilitating the adjustment of the pressure plate position. Simultaneously, through the automatic rotation angle of the universal ball 203 and the guiding effect of the directional guide column 208, the pressure plate can be easily adjusted according to the shape and size of the workpiece. At the same time, the operation of the motion cylinder 202 can drive the pressure plate 201 to adjust its height, thereby adjusting the height of the pressure plate. Meanwhile, the guide rod 209 can limit the movement of the pressure plate 201, thus enabling the pressure plate to stably position and press workpieces of different shapes and sizes, keeping the workpiece stable during the processing. This embodiment specifically solves the problem in the prior art that the positioning and pressing fixture cannot be easily adjusted according to the shape and size of the workpiece, making the workpiece prone to displacement and movement during the processing, which affects the quality and efficiency of the pressing of the workpiece.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
