Description

Technical Field

[0001] The utility model belongs to the technical field of tooling fixtures, and in particular relates to a hydraulic valve block clamping tooling. Background Art

[0002] The hydraulic valve block is an important component of hydraulic equipment. Its internal structure is mainly a number of staggered or parallel hydraulic channels. The external contour of the hydraulic valve block is mostly a rectangular structure. However, in order to adapt to the layout of the hydraulic system pipeline, such as Figure 1 As shown, sometimes one side of the rectangular hydraulic valve block is processed into an inclined surface, and a hydraulic flow channel is opened on the inclined surface. In order to facilitate drilling on the inclined surface, special V-blocks are currently used to fix and clamp such hydraulic valve blocks. When clamping, the right angle relative to the inclined surface is clamped in the V-block, and the inclined surface is facing upward and horizontal. However, the angles between the inclined surfaces and the adjacent side surfaces of hydraulic valve blocks of different models may be different, so the same V-block cannot be used for positioning. If the same V-block is used for positioning, it will be impossible to ensure that the inclined surface is in a horizontal state. Therefore, in order to produce different models of such valve blocks, it is currently necessary to make special V-blocks for positioning for each type of valve block. This leads to an increase in production costs, and at the same time increases the maintenance and storage costs of the V-blocks. Utility Model Content

[0003] In order to solve the deficiencies in the prior art, the utility model provides a hydraulic valve block clamping tool, which can be adapted to clamp hydraulic valve blocks with inclined surfaces at different angles.

[0004] In order to achieve the purpose of this utility model, the following scheme is proposed:

[0005] A hydraulic valve block clamping tool comprises a cylinder, a bottom plate and a clamping component.

[0006] A V-shaped groove is provided on one side of the outer wall of the cylinder along the axial direction. The cylinder is horizontally arranged above a bottom plate with the V-shaped groove facing upwards, and the cylinder is swingably arranged around the axis. A tightening screw is provided on the end surface of the bottom plate corresponding to the cylinder.

[0007] The clamping assembly includes a rectangular frame arranged parallel to the top of the base plate, the projection of the cylinder on the base plate is located in the rectangular frame, and the rectangular frame is slidably provided with a pair of pressure strips, the sliding direction of which is parallel to the axis of the cylinder, the pressure strips are parallel to the base plate and perpendicular to the axis of the cylinder, and the clamping assembly is arranged to move in a direction perpendicular to the base plate.

[0008] The beneficial effect of the utility model is that when clamping hydraulic valve blocks of different specifications, the inclined surface can be adjusted to a horizontal state by swinging the cylinder, thereby adapting to inclined surfaces with different angles to facilitate drilling on the inclined surface, greatly reducing the number of V-blocks produced and reducing production costs.

[0015] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0016] like Figure 2 , Figure 4 As shown, a hydraulic valve block clamping tool comprises: a cylinder 1 and a clamping assembly.

[0017] A V-shaped groove 11 is provided on one side of the outer wall of the cylinder 1 along the axial direction. The cylinder 1 is horizontally arranged above a base plate 2 with the V-shaped groove 11 facing upward, and the cylinder 1 is swingably arranged around the axis. A tightening screw 21 is provided on the end face of the base plate 2 corresponding to the cylinder 1 for tightening the cylinder 1.

[0018] The clamping assembly includes a rectangular frame 3 arranged parallel to the top of the base plate 2. The projection of the cylinder 1 on the base plate 2 is located in the rectangular frame 3. The rectangular frame 3 is slidably provided with a pair of pressure strips 4. The sliding direction is parallel to the axis of the cylinder 1. The pressure strips are parallel to the base plate 2 and perpendicular to the axis of the cylinder 1. The clamping assembly is arranged to move in a direction perpendicular to the base plate 2.

[0019] When clamping, the hydraulic valve block is placed in the V-groove 11, and the side of the hydraulic valve block opposite to the inclined surface cooperates with the V-groove 11, with the inclined surface facing upward; the cylinder 1 is rotated to adjust the angle between the inclined surface and the horizontal plane. In the process, the bottom surface of the pressure strip 4 is used as a reference to move the rectangular frame 3 so that the bottom surface of the pressure strip 4 contacts the inclined surface. When the bottom surface of the pressure strip 4 is completely in contact with the inclined surface, the inclined surface of the hydraulic valve block is parallel to the bottom plate 2; the bottom plate 2 has been installed on the base of the drilling machine in advance, so the bottom plate 2 is in a horizontal state. When the inclined surface of the hydraulic valve block is parallel to the bottom plate 2, the inclined surface will also be in a horizontal state at the same time; the cylinder 1 is fixed with the tightening screw 21; the position of the pressure strip 4 on the rectangular frame 3 is adjusted along the direction of the axis of the cylinder 1, so that the pressure strip 4 is pressed on the edge of the top surface of the hydraulic valve block to avoid blocking the drilling position, and the relative position between the rectangular frame 3 and the bottom plate 2 is fixed so that the pressure strip 4 keeps pressing the hydraulic valve block. When clamping hydraulic valve blocks of different specifications, the inclined surface can be adjusted to a horizontal state by swinging the cylinder 1, thereby adapting to inclined surfaces with different angles to facilitate drilling on the inclined surface, greatly reducing the number of V-blocks produced and reducing production costs.

[0020] Preferably, Figure 2 , Figure 3 As shown, a semicircular worm wheel 12 is coaxially provided with the cylinder 1, and the worm wheel 12 and the V-shaped groove 11 are respectively arranged on two opposite sides of the cylinder 1, and the base plate 2 is provided with a worm 22 meshing with the worm wheel 12. The cylinder 1 can be driven to rotate around the axis by rotating the worm 22, so as to adjust the direction of the V-shaped groove 11 so as to adjust the inclined surface of the hydraulic valve block to a horizontal state, and the structure in which the worm 22 meshes with the worm wheel 12 has a self-locking function, which can lock the cylinder 1.

[0021] Further preferably, Figure 3 As shown, a semicircular groove 101 is provided on the outer circumferential surface of the middle section of the cylinder 1 for mounting the worm gear 12 to reduce the overall installation size of the clamping fixture and reduce the installation height.

[0022] Preferably, Figure 2 , Figure 4 As shown, four guide tubes 23 are vertically provided on the top surface of the base plate 2 corresponding to the four sides of the cylinder 1, and four guide rods 31 are vertically provided on the bottom surface of the rectangular frame 3. The guide rods 31 are respectively inserted into the guide tubes 23, and locking screws 24 are passed through the side walls of the guide tubes 23 for locking the guide rods 31, so that the relative positions of the rectangular frame 3 and the base plate 2 remain fixed.

[0023] Preferably, Figure 2 , Figure 4As shown, a pressure plate 41 is provided on the top surface of the pressure strip 4, and the pressure plate 41 protrudes from the pressure strip 4 toward one side of the middle of the rectangular frame 3, and screw rods 32 are passed through both ends of the rectangular frame 3. The front ends of the screw rods 32 are rotatably connected to the two pressure strips 4 respectively. When the hydraulic valve block is pressed, the top surface of the hydraulic valve block is pressed by the pressure plate 41, and the screw rod 32 can be rotated to make the pressure strip 4 press the end surface of the hydraulic valve block toward one side of the middle of the rectangular frame 3 to prevent the hydraulic valve block from moving along the axis of the cylinder 1.

[0024] The above is only a preferred embodiment of the utility model, and does not mean that it is the only one or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
