Description

Technical Field

[0001] This utility model relates to a support device, specifically a support device for the production of hydraulic components, and belongs to the field of hydraulic component production technology. Background Technology

[0002] As the core pressure-bearing component of a hydraulic cylinder, the smoothness of its inner wall, cylindricity, and straightness of its axis directly affect the sealing performance and transmission accuracy of the hydraulic system. Cylinders are mostly slender structures; when fixed at a single point by a lathe chuck, the middle section is prone to deflection due to its own weight. This results in dimensional errors such as a thicker middle and thinner ends after machining, and may even lead to taper on the inner wall, failing to meet the sealing requirements of the piston's reciprocating motion. A center rest serves as an intermediate auxiliary support, lifting the middle of the cylinder, counteracting the effects of gravity, and preventing deformation.

[0003] For example, a polishing mechanism for hydraulic component processing is disclosed in patent CN223098880U. Although it achieves rotary processing, it lacks auxiliary support components. In the prior art, the support components of some center frames are in static contact with the outer circle of the cylinder. During processing, the high-speed rotation of the cylinder will generate sliding friction, which can easily scratch the outer circle surface of the cylinder and may also cause local deformation of the cylinder due to frictional heat, further affecting the processing accuracy of the inner wall. At the same time, the adjustment of its support spacing is not precisely synchronized, and the parameters on both sides are difficult to match. The cylinder axis is easily offset due to the imbalance of the support, which will destroy the coaxiality of the processing. Utility Model Content

[0004] The purpose of this utility model is to provide a support device for the production of hydraulic components in order to solve the above problems. The bidirectional screw rotates, causing the sliders at both ends to slide synchronously. Then, the rollers driven by the bracket adjust the spacing, avoid component offset and ensure the coaxiality of the support to improve processing accuracy. The rotating rollers at the end of the bracket can fit tightly with the outer circle of the cylindrical hydraulic component, which increases the contact area to prevent the component from rolling off course. They can also rotate synchronously with the component to convert sliding friction into rolling friction, reducing scratches on the component surface.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a support device for hydraulic component production, comprising a support rod and a positioning block threadedly installed on the side wall of the support rod. A fixing mechanism is installed at the bottom end of the support rod. A crossbar is sleeved between two support rods. Both ends of the crossbar abut against the positioning block. A driving mechanism is rotatably installed inside the crossbar. A limiting mechanism is slidably installed inside the crossbar. The limiting mechanism includes a slider and a bidirectional screw. The bidirectional screw is rotatably installed inside the crossbar and fixed to the driving mechanism. Both ends of the bidirectional screw are threadedly connected to sliders. A bracket is fixedly installed on the slider. A roller is rotatably connected to the end of the bracket away from the slider.

[0006] Preferably, the limiting mechanism further includes a sliding groove, the crossbar is provided with a sliding groove, a slider is slidably installed in the sliding groove, and a bidirectional screw is rotatably installed in the sliding groove.

[0007] Preferably, the driving mechanism includes a worm and a worm wheel, with a worm rotatably connected to one end of the crossbar, a worm wheel meshing on the worm, and a bidirectional screw fixedly connected to the worm wheel.

[0008] Preferably, the height of the groove is equal to the height of the slider, and the bracket and the crossbar are slidably connected.

[0009] Preferably, the fixing mechanism includes a base plate and a mounting bracket. The bottom end of the support rod is fixedly connected to the base plate, and two mounting brackets are symmetrically fixedly installed on the base plate. The mounting brackets are fixedly connected to the bed guide rail by bolts.

[0010] Preferably, the card holder is located at the end of the base plate away from the support rod, and the part of the card holder that contacts the bed guide rail is set with an inclined structure.

[0011] Preferably, the positioning block is arranged in a regular hexagonal structure, and the two ends of the crossbar are located between the two positioning blocks.

[0012] Preferably, the two sets of brackets and rollers are arranged symmetrically, and the rollers are provided with V-shaped grooves.

[0013] The beneficial effects of this utility model are as follows: the support rod provides a vertical support benchmark for the entire equipment; the positioning block is threaded onto the side wall of the support rod, and its height can be adjusted by rotation, thereby quickly positioning the installation position of the crossbar; the crossbar serves as a horizontal support carrier, and the drive mechanism drives the bidirectional screw to rotate. The sliders at both ends of the bidirectional screw can slide synchronously towards or in opposite directions due to the opposite screw rotation directions, thereby adjusting the spacing through the bracket and the rollers, avoiding component offset caused by inconsistent spacing on both sides during adjustment, ensuring the coaxiality of the hydraulic component support, and improving processing accuracy; the rollers at the end of the bracket adopt a rotating connection design, and the rollers can fit tightly with the outer circle of cylindrical hydraulic components, increasing the contact area, preventing rolling offset of the components during processing, and improving support stability; on the other hand, the rollers can rotate synchronously with the rotation of the components, converting traditional sliding friction into rolling friction, reducing scratches on the surface of the components, and is especially suitable for hydraulic components with high surface precision requirements.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5As shown, a support device for producing hydraulic components includes a support rod 2 and a positioning block 3 threadedly installed on the side wall of the support rod 2. A fixing mechanism 1 is installed at the bottom end of the support rod 2. A crossbar 4 is sleeved between two support rods 2, with both ends of the crossbar 4 abutting against the positioning block 3. The crossbar 4 is sleeved on the two support rods 2 so that both ends of the crossbar 4 abut against the fixed positioning block 3. Another set of positioning blocks 3 is threadedly fixed to the side wall of the support rod 2. When the positioning block 3 rotates to the state of abutting against the two ends of the crossbar 4, the crossbar 4 can be fixed between the two positioning blocks 3. By adjusting the height of the positioning block 3, hydraulic components of different heights can be quickly adapted. A drive mechanism 5 is rotatably installed inside the crossbar 4, and a limit mechanism 6 is slidably installed inside the crossbar 4. The limit mechanism 6 includes a slider 604 and a bidirectional screw 605. The bidirectional screw 605 is rotatably installed inside the crossbar 4 and fixed to the drive mechanism 5. Both ends of the bidirectional screw 605 are threadedly installed on the crossbar 4. A slider 604 is threadedly connected, and a bracket 601 is fixedly mounted on the slider 604. A roller 602 is rotatably connected to the end of the bracket 601 opposite to the slider 604. A groove 603 is provided in the crossbar 4, and the slider 604 is slidably mounted in the groove 603. The slider 604 drives the roller 602 to adjust the distance through the bracket 601 until the V-shaped groove in the roller 602 fits with the outer circle of the hydraulic component to be processed. The groove 603 restricts the up and down movement of the slider 604, ensuring adjustment accuracy and avoiding component offset caused by inconsistent spacing on both sides. A bidirectional screw 605 is rotatably mounted in the groove 603. The two sets of brackets 601 and rollers 602 are symmetrically arranged. The rollers 602 are provided with V-shaped grooves. When the lathe is started and the component rotates, the rollers 602 rotate synchronously with the component, converting sliding friction into rolling friction. At the same time, the V-shaped groove increases the contact area, preventing the component from rolling off course and ensuring that the component axis is coaxial with the spindle of the equipment during processing.

[0022] As a technical optimization of this utility model, the drive mechanism 5 includes a worm 501 and a worm wheel 502. One end of the crossbar 4 is rotatably connected to the worm 501, and the worm wheel 502 is meshed on the worm 501. A bidirectional screw 605 is fixedly connected to the worm wheel 502. The height of the slide groove 603 is equal to the height of the slider 604. When the worm 501 installed at one end of the crossbar 4 is rotated, the worm 501 meshes and drives the worm wheel 502 to rotate inside the crossbar 4, rotating synchronously with the bidirectional screw 605 fixed on the worm wheel 502. Because the threads at both ends of the bidirectional screw 605 are in opposite directions, the slider 604 connected by its threads will slide synchronously towards or in opposite directions. The bracket 601 is slidably connected to the crossbar 4.

[0023] As a technical optimization of this utility model, the fixing mechanism 1 includes a base plate 101 and a mounting bracket 102. The bottom end of the support rod 2 is fixedly connected to the base plate 101. Two mounting brackets 102 are symmetrically fixedly installed on the base plate 101. The mounting brackets 102 are fixedly connected to the bed guide rail 103 by bolts. The inclined surface of the mounting bracket 102 can make close contact with the bed guide rail 103, thereby limiting the lateral movement of the support component. At the same time, the base plate 101 increases the contact area to ensure the overall stability of the equipment and avoid deviation caused by processing vibration. The mounting bracket 102 is located at the end of the base plate 101 away from the support rod 2. The part of the mounting bracket 102 that contacts the bed guide rail 103 is set with an inclined structure.

[0024] As a technical optimization of this utility model, the positioning block 3 is set in a regular hexagonal structure. The positioning block 3, which is in a regular hexagonal structure, is rotated using a tool and threaded onto the side wall of the support rod 2, thereby adjusting the height of the positioning block 3 on the support rod 2; the two ends of the crossbar 4 are located between the two positioning blocks 3.

[0025] In use, the operator first places the base plate 101 at the bottom of the support rod 2 next to the lathe bed guide rail 103, so that the two retainers 102 on the base plate 101 are in contact with the side wall of the bed guide rail 103. The retainers 102 are then fastened to the bed guide rail 103 with bolts. The inclined surface of the retainers 102 allows for close contact with the bed guide rail 103, thus limiting the lateral movement of the support assembly. Simultaneously, the base plate 101 increases the contact area, ensuring overall equipment stability and preventing displacement caused by processing vibration. Next, a tool is used to rotate the hexagonal positioning block 3, threading it onto the side wall of the support rod 2, thereby adjusting the height of the positioning block 3 on the support rod 2. Then, the crossbar 4 is sleeved onto the two support rods 2, so that both ends of the crossbar 4 abut against the fixed positioning blocks 3. Another set of positioning blocks 3 is then threaded onto the side wall of the support rod 2. When the positioning blocks 3 are rotated to abut against both ends of the crossbar 4, the crossbar 4 can be fixed between the two positioning blocks 3. The height adjustment of section 3 allows for quick adaptation to hydraulic components of different heights. Rotating the worm gear 501 mounted at one end of the crossbar 4 causes the worm gear 502 to rotate within the crossbar 4, synchronously rotating with the bidirectional screw 605 fixed on the worm gear 502. Because the threads at both ends of the bidirectional screw 605 rotate in opposite directions, the threaded sliders 604 will slide synchronously towards or away from each other. The sliders 604, through the bracket 601, drive the rollers 602 to adjust the spacing until the V-groove within the rollers 602 fits against the outer diameter of the hydraulic component to be processed. The groove 603 restricts the vertical movement of the sliders 604, ensuring adjustment accuracy and preventing component misalignment caused by inconsistent spacing on both sides. Next, the hydraulic component is placed in the V-groove of the rollers 602 on both sides. The lathe is then started. As the component rotates, the rollers 602 rotate synchronously with it, converting sliding friction into rolling friction. Simultaneously, the V-groove increases the contact area, preventing component roll misalignment and ensuring that the component axis is coaxial with the machine spindle during processing, thus improving processing accuracy.
