Description

Technical Field

[0001] This utility model belongs to the field of distribution plate processing, specifically an oil distribution plate processing device. Background Technology

[0002] The distributor plate is a core component of hydraulic motors and pumps, managing high and low pressure oil distribution through plunger chamber pressure management and oil circuit switching. As shown in the figure, the distributor plate needs to be machined during manufacturing to obtain structures such as the spherical cylinder block mating surface, auxiliary support band, oil sealing band, oil distribution window, unloading groove, and throttling orifice. Traditional machining fixtures generally use chucks to tighten the distributor plate from the inside or clamp it from the outside. This only allows machining on one side, requiring disassembly, rotation by 180°, and re-clamping to complete the machining on the other side. This necessitates two clamping operations to complete the machining, resulting in significant machining errors. Utility Model Content

[0003] To solve the above-mentioned technical problems, the inventors, through practice and summarization, derived the technical solution of this utility model, which adopts the following technical solution:

[0004] An oil distribution plate processing device includes clamping claws and an upper pusher. The clamping claws are symmetrically distributed in two sets. Each set of clamping claws includes a movable body and a clamping body. The clamping body is rotatably arranged relative to the movable body and is used to clamp and fix the oil distribution plate from the outside. The upper pusher is distributed at the bottom of the two sets of clamping claws and is used to push and fix the oil distribution plate upward.

[0005] In the processing device, hydraulic cylinders are installed on the side of the two sets of moving bodies facing away from the clamping body. The piston rod end of the hydraulic cylinder is connected to the moving body and is used to drive the moving body to approach or move away from the oil distribution plate.

[0006] In the processing device, the clamping jaw includes a rotating body and a clamping body fixed to one end of the rotating body. The end of the rotating body away from the clamping body and the moving body are rotatably engaged by a bearing. The side of the clamping body facing away from the rotating body is provided with an arc-shaped surface to adapt to the outer surface of the oil distribution plate.

[0007] In the processing device, the moving body is provided with constraint holes, and the inner wall of the constraint holes is provided with constraint grooves. The end of the rotating body away from the clamping body is provided with a countersunk hole, and the inner wall of the countersunk hole is provided with a radial hole. An elastic constraint member is installed in the radial hole. The elastic constraint member and the constraint groove are positioned correspondingly and are mutually adapted.

[0008] In the processing device, the constraint groove includes two sets of centrally symmetrically distributed arc-shaped guide grooves and a constraint sink groove located at the end of the arc-shaped guide groove. The depth of the constraint sink groove is greater than the depth of the arc-shaped guide groove. The depth of the arc-shaped guide groove gradually increases along the rotation direction of the rotating body. The end of the constraint sink groove and the beginning of the other set of arc-shaped guide grooves are connected by a circular arc transition.

[0009] In the processing device, the elastic constraint member includes a set screw, an elastic body, and a constraint body. The constraint body and the constraint groove are positioned correspondingly and are adapted to each other. The elastic body is located between the constraint body and the set screw. The set screw is threadedly connected to the radial hole.

[0010] In the processing device, there are two sets of upper pushers, and the arrangement directions of the two sets of upper pushers and the arrangement directions of the two sets of clamping claws are perpendicular to each other.

[0011] The upper pusher includes a pusher cylinder and a ball head structure fixed to the end of the piston rod of the pusher cylinder.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention employs two clamping jaws to hold the distribution plate from the outside, and uses an upper lifting member to achieve close contact with the bottom surface of the distribution plate from the bottom, keeping the distribution plate horizontally placed. With the help of a CNC machining center, it can machine structures such as spherical cylinder mating surfaces, auxiliary support belts, oil sealing belts, oil distribution windows, unloading grooves, and throttling holes. The upper lifting member is removed from the bottom, and the distribution plate is rotated 180° manually or by lifting with the upper lifting member to complete the end face exchange. The upper lifting member is used again to achieve close contact from the bottom, thereby completing the machining operation on the other end face while ensuring the machining datum. Thus, the machining operation of the distribution plate can be completed with only one clamping, which is convenient to operate and has high machining accuracy. Attached Figure Description

[0023] Example 1

[0024] like Figures 1 to 4 As shown, an oil distribution plate processing device includes clamping claws 10 and upper pushers 20. The clamping claws 10 are symmetrically distributed in two sets. Each set of clamping claws 10 includes a movable body 12 and a clamping member 11. The clamping member 11 is rotatably arranged relative to the movable body 12 and is used to clamp and fix the oil distribution plate from the outside. The upper pushers 20 are distributed at the bottom of the two sets of clamping claws 10 and are used to push and fix the oil distribution plate upward.

[0025] The upper top member 20 is provided in two sets, and the two sets of upper top members 20 are arranged perpendicularly to the two sets of clamping claws 10.

[0026] The upper pusher 20 includes a pusher cylinder 21 and a ball head structure 22 fixed to the end of the piston rod of the pusher cylinder 21.

[0027] The push cylinders 21, distributed front and rear, drive the ball head structure 22 to move up and down through the piston rod to achieve close contact with the bottom surface of the distribution plate, so as to ensure that the distribution plate remains horizontal during processing.

[0028] The moving body 12 moves closer to or further away from the distribution plate, and the clamping member 11 clamps the distribution plate from the outside. To ensure the distribution plate is horizontal, the bottom upper support member 20 provides support to the bottom surface of the distribution plate in this state. This support is in close contact with the bottom surface of the distribution plate, preventing angular deviation during the machining of the top surface structure in this state and ensuring machining accuracy. After machining one end face, when machining the other end face, the bottom upper support member 20 is retracted, and the distribution plate is manually rotated 180°. After rotating 180°, the upper support member 20 is used again to provide close contact with the bottom surface in this state for machining the other end face. After machining both end faces, the distribution plate can be removed.

[0029] Example 2

[0030] In the first embodiment, as Figures 1 to 4 As shown, hydraulic cylinders 30 are installed on the side of the two sets of moving bodies 12 facing away from the clamping body 111. The piston rod end of the hydraulic cylinder 30 is connected to the moving body 12 and is used to drive the moving body 12 to move closer to or away from the distribution plate. The moving body 12 is moved left and right by the piston rod of the hydraulic cylinder 30, thereby completing the clamping and fixing operation of the distribution plate.

[0031] Example 3

[0032] In the first embodiment, as Figure 1 , 4 As shown, the clamping member 11 includes a rotating body 112 and a clamping body 111 fixed to one end of the rotating body 112. The end of the rotating body 112 away from the clamping body 111 and the moving body 12 are rotatably engaged by a bearing. The side of the clamping body 111 facing away from the rotating body 112 is provided with an arc-shaped surface to adapt to the outer surface of the oil distribution plate, and a step body is provided at the bottom. The top surface of the step body is a spherical structure for adapting to and positioning the spherical structure of the oil distribution plate.

[0033] Before clamping, the oil distribution plate is positioned using the stepped body. The hydraulic cylinder 30 is used to clamp the oil distribution plate with the clamping body 111. The rotating body 112 and the moving body 12 are used to rotate the oil distribution plate 180° in the clamping state, so as to complete the machining of the two sides after one clamping.

[0034] Example 4

[0035] In the described embodiment 3, as Figure 2 , 5As shown in Figure 6, the movable body 12 is provided with constraint holes 13, and constraint grooves 14 are provided on the inner wall of the constraint holes 13. The rotating body 112 is provided with a countersunk hole 113 at the end away from the clamping body 111. A radial hole 114 is provided on the inner wall of the countersunk hole 113. An elastic constraint member is installed in the radial hole 114. The elastic constraint member and the constraint groove 14 are in corresponding positions and are adapted to each other.

[0036] The constraint groove 14 includes two sets of centrally symmetrically distributed arc-shaped guide grooves 141 and a constraint sink 142 located at the end of the arc-shaped guide groove 141. The depth of the constraint sink 142 is greater than the depth of the arc-shaped guide groove 141. The depth of the arc-shaped guide groove 141 gradually increases along the rotation direction of the rotating body 112. The end of the constraint sink 142 and the beginning of the other set of arc-shaped guide grooves 141 are connected by an arc transition.

[0037] The elastic constraint includes a set screw 115, an elastic body 116, and a constraint body 117. The constraint body 117 and the constraint groove 14 are positioned correspondingly and adapted to each other. The elastic body 116 is located between the constraint body 117 and the set screw 115. The set screw 115 is threadedly connected to the radial hole 114.

[0038] After one end face is processed, in order to complete the automated flipping operation, two sets of front and rear distributed upper pushers 20 are used. The piston rod of the front pusher cylinder 21 extends outward, and the piston rod of the rear pusher cylinder 21 retracts inward. The constraint body 117 enters the arc-shaped guide groove 141 through an arc transition. Then, the piston rod of the pusher cylinder 21 retracts completely to not hinder the 180° rotation of the distribution plate. Under the synergy of the outward extrusion of the elastic body 116 and the depth change of the arc-shaped guide groove 141, the constraint body 117 re-enters the other constraint groove 142, completing the 180° rotation to change the two end faces. Finally, the piston rod of the pusher cylinder 21 extends outward and uses the ball head structure 22 to make close contact with the bottom surface of the distribution plate at this time, so that the distribution plate is in a horizontal state in this state, and the top surface processing operation is carried out in this state.

[0039] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
