Description

Technical Field

[0001] This utility model relates to the field of valve body processing technology, specifically to a tooling for processing hydraulic pilot handle valve bodies. Background Technology

[0002] In modern industry, hydraulic systems are widely used in various types of machinery and equipment, such as construction machinery, aerospace equipment, and industrial automated production lines. As a key component in a hydraulic system that controls the flow and pressure of hydraulic oil, the quality of the hydraulic pilot handle's valve body directly affects the performance, reliability, and service life of the entire hydraulic system.

[0003] Traditional machining methods typically require the use of fixtures to position and hold the valve body during processing. However, ordinary fixtures cannot provide stable clamping force during the clamping process. As a result, excessive clamping force may cause the valve body to deform, thereby affecting the internal dimensional accuracy and surface roughness of the valve body, and reducing the valve body's sealing performance and fluid transmission capacity.

[0004] In response to the problems raised in the above article, we propose a machining fixture for the hydraulic pilot handle valve body. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, this utility model provides a hydraulic pilot handle valve body machining fixture, which can effectively solve the problems in the existing technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a machining fixture for a hydraulic pilot handle valve body, including a base frame and a machining plate. An adjusting circular plate is rotatably connected to the top of the base frame, a positioning block is fixedly installed on the top of the machining plate, and an electric telescopic rod is fixedly connected to the top of the adjusting circular plate. The output end of the electric telescopic rod is fixedly connected to the machining plate.

[0008] The processing plate is equipped with a limit component inside, and the top of the adjustment plate is equipped with an adjustment component.

[0009] According to the above-mentioned hydraulic pilot handle valve body machining fixture, the limiting component includes a bidirectional threaded rod, which is located inside the machining plate and rotatably connected thereto. An adjusting disc is rotatably connected to one side of the machining plate, and the adjusting disc is fixedly connected to the bidirectional threaded rod. Two sliders are threadedly connected to the outer side of the bidirectional threaded rod. A connecting block is fixedly connected to the top of the slider, a clamping block is fixedly connected to one side of the connecting block, and a clamping ring is fixedly connected to one side of the clamping block.

[0010] According to the above-mentioned hydraulic pilot handle valve body machining fixture, a rack is slidably connected inside the connecting block, and a second gear is rotatably connected inside the clamping block. The rack meshes with the second gear, and the rack passes through the clamping ring without contacting it. Two pulleys are rotatably connected inside the connecting block. A transmission belt is rotatably connected to the outside of one of the pulleys. One of the pulleys is connected to the other pulley via the transmission belt. The second gear is fixedly connected to one of the pulleys.

[0011] According to the above-mentioned hydraulic pilot handle valve body machining fixture, the bottom of the clamping block is rotatably connected to two threaded rods, and the outer sides of the two threaded rods are threadedly connected to sliders. The bottom of the sliders is provided with a suction cup, and the two threaded rods are respectively fixedly connected to two pulleys.

[0012] According to the above-mentioned hydraulic pilot handle valve body machining fixture, the adjustment component includes a mounting frame, a motor is fixedly mounted on the top of the mounting frame, a gear is rotatably connected to the top of the base frame, the output end of the motor is fixedly connected to the gear, and a gear ring is fixedly connected to the outer side of the adjustment circular plate, the gear ring meshing with the gear.

[0014] According to the above-mentioned hydraulic pilot handle valve body machining fixture, a control panel is fixedly installed on the top of the base frame, and the motor and the electric telescopic rod are both electrically connected to the control panel.

[0015] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0016] This invention utilizes a limiting component and an adjusting disc to drive a bidirectional threaded rod. During operation, the threaded rod drives two sliders to move towards or away from each other. During clamping, the two sliders move towards each other, causing the clamping ring to contact the valve body. The clamping ring is made of a deformable material. After contact, the rack contacts the valve body and moves inwards towards the clamping block. The rack then meshes with gear two, driving gear two to rotate. Gear two then drives a pulley, which, through its interaction with a transmission belt, rotates synchronously. This pulley drives the threaded rod, causing slider two to move downwards and the suction cup to contact the surface of the processing plate. The bidirectional threaded rod then stops rotating, completing the clamping process. This prevents excessive clamping force, which could deform the valve body and affect its internal dimensional accuracy and surface roughness. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Example: Refer to Figures 1 to 4 The hydraulic pilot handle valve body machining fixture includes a base frame 1 and a machining plate 3. An adjusting circular plate 2 is rotatably connected to the top of the base frame 1. A positioning block 36 is fixedly installed on the top of the machining plate 3. An electric telescopic rod 25 is fixedly connected to the top of the adjusting circular plate 2. The output end of the electric telescopic rod 25 is fixedly connected to the machining plate 3.

[0026] The processing plate 3 is equipped with a limiting component inside, and the top of the adjusting circular plate 2 is equipped with an adjusting component. The valve body is precisely limited by the limiting component, thereby improving the clamping accuracy. The angle can also be adjusted by the limiting component for processing.

[0027] The limiting assembly includes a bidirectional threaded rod 32, which is located inside and rotatably connected to the processing plate 3. An adjusting disc 31 is rotatably connected to one side of the processing plate 3, and the adjusting disc 31 is fixedly connected to the bidirectional threaded rod 32. Two sliders 33 are threadedly connected to the outer side of the bidirectional threaded rod 32. A connecting block 34 is fixedly connected to the top of each slider 33. A clamping block 35 is fixedly connected to one side of the connecting block 34, and a clamping ring 37 is fixedly connected to one side of the clamping block 35. The adjusting disc 31 drives the bidirectional threaded rod 32 to rotate. During rotation, the bidirectional threaded rod 32 drives the two sliders 33 to move towards or away from each other. During clamping, the two sliders 33 move towards each other, causing the clamping ring 37 to contact the valve body. A rack 38 is slidably connected inside the connecting block 34. A gear 42 is rotatably connected inside the clamping block 35. The rack 38 meshes with the gear 42, passing through the clamping ring 37 without contacting it. Two pulleys 43 are rotatably connected inside the connecting block 34, one of which... A transmission belt 44 is rotatably connected to the outer side of the clamping block 35. One pulley 43 is connected to the other pulley 43 via the transmission belt 44. Gear 42 is fixedly connected to one of the pulleys 43. After the clamping ring 37 contacts, the rack 38 contacts the valve body and moves towards the inside of the clamping block 35. Then, the rack 38 meshes with gear 42. Two threaded rods 40 are rotatably connected to the bottom of the clamping block 35. Slider 39 is threadedly connected to the outer side of each threaded rod 40. A suction cup 41 is provided at the bottom of the slider 39. The two threaded rods 40 are fixedly connected to the two pulleys 43 respectively. Through the cooperation of the pulleys 43 and the transmission belt 44, the two pulleys 43 rotate synchronously and drive the threaded rods 40 to rotate, causing the sliders 39 to move down and the suction cup 41 to contact the surface of the processing plate 3. Thus, the bidirectional threaded rods 32 stop rotating, completing the clamping and avoiding excessive clamping force, which could cause valve body deformation and affect the internal dimensional accuracy and surface roughness of the valve body.

[0028] The adjustment assembly includes a mounting frame 22, with a motor 23 fixedly mounted on the top of the mounting frame 22. A gear 24 is rotatably connected to the top of the base frame 1. The output end of the motor 23 is fixedly connected to the gear 24. A gear ring 21 is fixedly connected to the outer side of the adjustment disc 2, and the gear ring 21 meshes with the gear 24. The motor 23 drives the gear 24 to rotate, causing the gear 24 to mesh with the gear ring 21, thereby driving the adjustment disc 2 to rotate and adjust the angle of the processing plate 3 for processing. The lowest point of the suction cup 41 is lower than the threaded rod 40. The slider 39 is slidably connected to the connecting block 34. The lowest point of the suction cup 41 is lower than the threaded rod 40 to facilitate contact between the suction cup 41 and the processing plate 3, thereby achieving limit positioning. A control panel 11 is fixedly mounted on the top of the base frame 1. The motor 23 and the electric telescopic rod 25 are both electrically connected to the control panel 11. The control panel 11 allows the user to operate the device.

[0029] The working principle of this utility model is as follows: The valve body to be processed is placed on the surface of the positioning block 36. Then, the bidirectional threaded rod 32 is driven to rotate by the adjusting plate 31. During the rotation of the bidirectional threaded rod 32, the two sliders 33 move towards each other or away from each other. When clamping, the two sliders 33 move towards each other, causing the clamping ring 37 to contact the valve body. The clamping ring 37 is made of deformable material. After the clamping ring 37 contacts the valve body, the rack 38 will contact the valve body, causing the rack 38 to move towards the inside of the clamping block 35. Then, the rack 38 meshes with the gear 42, thereby driving the gear 42 to rotate, and driving the pulley 43 to rotate through the gear 42. The transmission belt 44, in conjunction with the two pulleys 43, causes the two pulleys 43 to rotate synchronously. The pulleys 43 drive the threaded rod 40 to rotate, causing the slider 39 to move downwards and the suction cup 41 to contact the surface of the processing plate 3. This stops the bidirectional threaded rod 32 from rotating, completing the clamping process and preventing excessive clamping force that could deform the valve body. After clamping, the motor 23 drives the gear 24 to rotate, causing the gear 24 to mesh with the gear ring 21. This drives the adjusting disc 2 to rotate, adjusting the angle of the processing plate 3 for processing. At the same time, the electric telescopic rod 25 can be used to adjust the height of the processing plate 3 accordingly, improving the flexibility of the device.

[0030] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
