Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing, in particular to a turning tool for processing a hydraulic gear pump. Background Art

[0002] In the production of hydraulic gear pumps, flipping fixtures play a vital role, primarily used to improve machining efficiency, ensure machining accuracy, and simplify operating procedures. This type of fixture is particularly suitable for complex components that require multi-sided precision machining, such as the internal gears and housings of hydraulic gear pumps. By using a flipping fixture, the operator can quickly flip or reposition the workpiece without removing it, thereby reducing changeover time and improving machine tool efficiency. In addition, the flipping fixture helps maintain accuracy during machining by fixing and precisely positioning the workpiece, reducing alignment errors that may be introduced by re-clamping. As the manufacturing industry develops towards intelligence and automation, the design of modern flipping fixtures is becoming more and more flexible, and can be integrated with CNC programs, robotic operating systems, etc. to meet the needs of efficient and precise production.

[0003] A search revealed an existing patent (publication number: CN218946798U) that discloses a turning tool for machining rail passenger car bogies. The tool comprises an upper base and a lower base, with a weight block positioned between them. A first fixing block is positioned on either side of the weight block. The first fixing block is provided with a first connecting block and a second connecting block at each end, respectively. A second fixing block is provided at the other end of the first and second connecting blocks. A third connecting block is positioned midway between the weight block, and a fifth fixing block is positioned midway between the third connecting block. A rotating block is provided at one end of the fifth fixing block, and a cross fixing block is provided at one end of the rotating block. This utility model enables required operations on rail passenger car bogies in all directions, as well as the addition of small parts. This greatly facilitates work while ensuring worker safety, making it suitable for widespread promotion and use.

[0004] However, in practice, the above solution only allows for flipping in one direction. Therefore, for parts requiring multi-angle machining, all machining surfaces may not be accessible. This limits the workpiece's machining range and flexibility. Furthermore, to machine surfaces that cannot be directly accessed via single-direction flipping, the operator may need to manually re-clamp the workpiece multiple times. This not only increases machining time but also potentially impacts production efficiency.

[0005] To this end, the utility model provides a turning tool for processing a hydraulic gear pump. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology and solve the problem that the turning can only be performed in one direction, then for parts that require multi-angle processing, all processing surfaces may not be accessible, which limits the processing range and flexibility of the workpiece, the utility model proposes a turning tool for hydraulic gear pump processing.

[0007] The technical solution adopted by the utility model to solve its technical problems is: the utility model is a turning tool for hydraulic gear pump processing, comprising a base, the top end of the rear side of the base is fixedly connected to the support frame, the top end of the rear side of the support frame is fixedly connected to the first motor, the output end of the first motor is fixedly connected to the transmission rod, the middle end outer side of the transmission rod is rotatably connected to the first limiting frame, the bottom end of the first limiting frame is fixedly connected to the top end of the support frame, the front end of the transmission rod is provided with a clamping assembly, the front end of the clamping assembly is provided with first clamping arms opposite to the left and right, the front end outer side of the first clamping arm is fixedly connected to the second motor, the output end of the second motor is fixedly connected to the third fixing plate, the inner side of the third fixing plate is fixedly connected to the limiting column away from the outer side of one end of the second motor, and the outer wall of one end of the inner side of the limiting column is fixedly connected to the second limiting frame;

[0008] Through the above technical solution, the first motor uses the transmission rod to drive the front end structure to perform overall horizontal flipping, and cooperates with the second motor to drive the third fixed plate, the limit column, the second limit frame, the limit assembly and the workpiece to perform longitudinal flipping, thereby realizing multi-angle flipping of the processed workpiece, thereby facilitating subsequent processing.

[0009] Furthermore, the clamping assembly includes an electric push rod, the front end of the transmission rod is fixedly connected to a first fixed plate, the outer side of the front end of the first fixed plate is fixedly connected to evenly distributed connecting rods, the front end of the connecting rod is fixedly connected to a limit plate, the middle side of the rear end of the limit plate is fixedly connected to an electric push rod, the left side of the electric push rod is fixedly connected to a transmission plate, the middle side of the front end of the limit plate is rotatably connected to a transmission gear, the outer side of the transmission gear is meshed with upper and lower opposite racks, the outer side of the rack is fixedly connected to a second fixed plate, the front end of the second fixed plate is slidably connected to the first clamping arm, and the second fixed plate on the left side is fixedly connected to the transmission plate;

[0010] Through the above technical solution, the first clamping arm and the front end structure are driven by the clamping assembly to move in opposite directions, thereby fixing the workpiece.

[0011] Furthermore, the front end of the limit plate is fixedly connected to a slide rail facing up and down, the outer side of the front end of the slide rail is slidably connected to a slider, and the slider is fixedly connected to the upper end of the first clamping arm;

[0012] Through the above technical solution, the slide rail and the slider cooperate with each other to provide position-limiting support for the second fixed plate, so that the second fixed plate can slide smoothly.

[0013] Furthermore, the second limiting frame is rotatably connected to the second clamping arm on the inner side, one end of the inner side of the second clamping arm is rotatably connected to the connecting frame, the inner side of the connecting frame is fixedly connected to the transmission frame, the transmission frame is slidably connected to the limiting column, the inner top end of the transmission frame is fixedly connected to the top plate, the bottom end of the top plate is fixedly connected to the spring, and the bottom end of the spring is fixedly connected to the third fixing plate;

[0014] Through the above technical solution, when the first clamping arm drives the limiting assembly to move inward to fix the workpiece, the workpiece squeezes the transmission frame, forcing the transmission frame to move inward, thereby driving the second clamping arm through the connecting frame to rotate at the connection position between the second clamping arm and the second limiting frame, thereby adaptively clamping the workpiece again through the second clamping arm, thereby increasing the stability of the workpiece.

[0015] Furthermore, the bottom end of the base is fixedly connected with evenly distributed supporting feet;

[0016] Through the above technical solution, the base is supported by the supporting legs.

[0017] Furthermore, a rubber layer is provided on the top of the transmission frame;

[0020] 1.

[0021] 2. The turning tool for hydraulic gear pump processing described in the utility model uses a first clamping arm to adaptively clamp the workpiece through a limit assembly during the movement of the object, thereby quickly and automatically adjusting to a state suitable for various workpieces, reducing the time for manual clamping and adjustment of the fixture and improving production efficiency.
