Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a hydraulic valve block clamping tool. Background Technology

[0002] A hydraulic valve block is an automated component operated by pressurized oil. It is controlled by the pressurized oil of the pressure regulating valve and is usually used in combination with a solenoid pressure regulating valve. It can be used for remote control of the on / off of oil, gas and water pipeline systems in hydropower stations. It serves as both a support plate for other hydraulic components and a channel for connecting oil circuits. The material is generally steel plate or malleable cast iron, and the structure is generally square.

[0003] The existing Chinese patent with publication number CN221658666U discloses a positioning fixture for machining the valve core hole of a hydraulic valve block. The existing technical solution described above has the following defects: Although the above technical solution uses a first servo motor to drive two fastening mechanisms to move closer to each other at both ends of the hydraulic valve block, and then rotates a second bidirectional lead screw to drive two fastening components to move closer to each other, so that the two clamping blocks clamp the front and back of the hydraulic valve block, and then cooperates with the rotation of a third bidirectional lead screw to drive two clamping plates to move closer to each other, clamping the top and bottom of the hydraulic valve block to complete the fastening and clamping of the hydraulic valve block, in the above technical solution, the third bidirectional lead screw needs to be manually adjusted to achieve the clamping of the valve block. This manual operation method not only increases the complexity of operation, but also reduces the clamping efficiency. It is not convenient and efficient enough in actual production environment, which affects the practicality and automation level of the fixture. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a hydraulic valve block clamping fixture, which has the advantages of convenient and automatic clamping and fixing of valve blocks, strong practicality, and high degree of automation, thereby solving the problems mentioned in the background technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a hydraulic valve block clamping fixture, comprising a base, a dual-axis motor fixedly installed at the middle position inside the base, and a screw fixedly connected to the output end of the dual-axis motor, a moving block threadedly connected to the screw, connecting grooves penetrating both sides of the top surface of the base, a connecting block penetrating the connecting groove at the middle position of the top surface of the moving block, and a mounting plate provided on one side surface of the connecting block, a servo motor fixedly installed on one side surface of the mounting plate, a connecting box fixedly connected to the output end of the servo motor, a first rack provided on one side inside the connecting box, a second rack provided on one side of the first rack inside the connecting box, a gear provided between the first rack and the second rack, a clamping block fixedly connected to one side surface of the first rack and the second rack through a through groove on one side surface of the connecting box, and an abutment block fixedly connected to the clamping block, a limiting rod penetrating the clamping block inside the connecting box, and an electric push rod fixedly installed on one side surface of the bottom surface of the connecting box, the output end of the electric push rod penetrating the bottom surface of the connecting box and fixedly connected to the clamping block.

[0006] Preferably, the bottom surface of the movable block is provided with a limiting block, and one end of the limiting block extends into the interior of the limiting grooves opened on both sides of the bottom upper surface of the base.

[0013] Compared with the prior art, this utility model provides a hydraulic valve block clamping fixture, which has the following beneficial effects:

[0014] (1) In this utility model, the initial distance between the clamping blocks is first adjusted, and then the valve block is placed on the surface of the abutting block on the clamping block. After the electric push rod at the bottom of the connecting box is started, the electric push rod drives the second rack to move upward, and at the same time drives the first rack to move downward synchronously through gear transmission, so that the clamping blocks on both sides generate relative displacement. When the abutting block and the valve block are in complete contact, automatic clamping and fixing are achieved. This process does not require manual intervention, which significantly improves the clamping efficiency and automation level. In addition, by starting the servo motor on the side of the mounting plate, the connecting box can be driven to rotate the clamping mechanism as a whole, thereby realizing the adjustment of the processing angle of the valve block, which facilitates multi-directional processing of the valve block and greatly improves the practicality and processing flexibility of the equipment.

[0015] (2) In this utility model, the screw is driven to rotate by the dual-axis motor in the base. Under the cooperation of the limiting block and the limiting groove, the moving block is ensured to move stably along the screw. At the same time, the moving block drives the connecting block to move synchronously in the connecting groove of the base, thereby accurately adjusting the distance between the clamping mechanisms. This effectively solves the clamping requirements of valve blocks of different sizes, significantly improves the applicability of the equipment, reduces the limitations of use, enhances the adaptability of the fixture to workpieces of different specifications, and further optimizes the processing efficiency and ease of operation.

An electric push rod 18 is fixedly installed on one side of the bottom surface of the connecting box 11, and the output end of the electric push rod 18 passes through the bottom surface of the connecting box 11 and is fixedly connected to the clamping block 12. By adjusting the initial distance between the clamping blocks 12, the valve block is placed on the surface of the abutment block 13 on the clamping block 12. After starting the electric push rod 18 at the bottom of the connecting box 11, the electric push rod 18 drives the second rack 17 to move upward, and at the same time drives the first rack 15 to move downward synchronously through the gear 16, so that the clamping blocks 12 on both sides generate relative displacement. When the abutment block 13 is in complete contact with the valve block, automatic clamping and fixing are achieved. This process does not require manual intervention, which significantly improves the clamping efficiency and automation level. In addition, by starting the servo motor 10 on the side of the mounting plate 9, the connecting box 11 can be driven to rotate the entire clamping mechanism, thereby realizing the adjustment of the processing angle of the valve block, which facilitates multi-directional processing of the valve block and greatly improves the practicality and processing flexibility of the equipment.

[0026] In one embodiment, the bottom surface of the movable block 5 is provided with a limiting block 4, and one end of the limiting block 4 extends into the interior of the limiting groove 3 opened on both sides of the bottom upper surface of the base 1.

[0027] In one embodiment, the clamping block 12 and the through groove 14 are rectangular structures. The clamping block 12 is slidably connected to the through groove 14, which facilitates the movement of the clamping block 12 in the through groove 14.

[0034] Working principle:

[0035] In use, first adjust the initial spacing between the clamping blocks 12, then place the valve block on the surface of the abutment block 13 on the clamping block 12. After activating the electric push rod 18 at the bottom of the connecting box 11, the electric push rod 18 drives the second rack 17 to move upward, and at the same time drives the first rack 15 to move downward synchronously through the gear 16, thereby causing relative displacement of the clamping blocks 12 on both sides. When the abutment block 13 is in full contact with the valve block, automatic clamping and fixing are achieved. This process does not require manual intervention, significantly improving clamping efficiency and automation level. In addition, by activating the servo motor 10 on the side of the mounting plate 9, it can be driven... The connecting box 11 drives the clamping mechanism to rotate as a whole, thereby adjusting the processing angle of the valve block, facilitating multi-directional processing of the valve block, and greatly improving the practicality and processing flexibility of the equipment. Specifically, by starting the dual-axis motor 6 in the base 1 to drive the screw 2 to rotate, the moving block 5 is ensured to move stably along the screw 2 under the cooperation of the limiting block 4 and the limiting groove 3.
