Description

Technical Field

[0001] This utility model relates to the technical field of electromagnetic valve processing equipment, specifically to a positioning and clamping electromagnetic valve grinding device. Background Technology

[0002] A solenoid valve is a basic automated component controlled by electromagnetic force. It is an actuator. The solenoid valve body is a cylindrical structure with one end closed and the other end open. During processing and installation, the inner wall of the solenoid valve body needs to be polished before the valve body can be installed more accurately. Currently, the polishing of the inner wall of the solenoid valve body needs to be done by fixing it with a clamping device. The stability and adaptability of the clamping structure directly determine the polishing quality and production efficiency.

[0003] The clamping blocks of existing grinding devices are mostly of fixed size, or the entire set of clamps is replaced to adapt to the shells of different diameters. For example, although the processing device proposed in the patent with publication number CN217253017U can clamp valve seats, it uses a symmetrical propulsion component to drive the clamping seat. It is necessary to replace the special clamping blocks for different shell diameters. The replacement process requires disassembling bolts and other parts, which is time-consuming and labor-intensive, and it is difficult to meet the needs of small-batch multi-specification production.

[0008] The clamping assembly includes a base, a first slide groove, and a clamping seat. A vertical rod is vertically arranged in the middle part of the base, passing through the first slide groove. The vertical rod is slidably connected to the first slide groove. A toothed plate is provided at the bottom end of the vertical rod. A fixed frame is provided at the lower end of the processing table. A first motor is provided at the bottom end of the fixed frame. A gear is provided at the output end of the first motor, located between two toothed plates. The gear meshes with the two toothed plates.

[0009] The upper end of the base is provided with a positioning seat, the positioning seat is provided with a positioning groove, the outer side of the clamping seat is provided with a positioning block that is inserted into the positioning groove, the inner wall of the positioning groove is provided with a slot, the two sides of the positioning block are provided with cavities, the cavities are provided with springs, and one end of the spring is provided with a locking block that cooperates with the slot.

[0010] To facilitate assembly of the clamping seat on the positioning seat, the improvement of this utility model is that all of the said clamping blocks are isosceles trapezoidal structures.

[0011] Furthermore, an improvement of this utility model is that one end of the spring is fixed inside the cavity, and the other end is connected to the locking block.

[0012] To improve the stability of the base during use, the present invention includes an improvement whereby the upper end of the processing table is provided with a guide rod that passes through both ends of the base and is slidably connected to the base.

[0013] Further improvements to this utility model include that the grinding assembly comprises a lifting assembly, a top plate, a top seat, a second motor, and a fourth motor. The lifting assembly is fixed to the upper end of the processing table, the top plate is fixed to the output end of the lifting assembly, the second motor is fixed to the lower end of the top plate, the top seat is fixed to the output end of the second motor, the top seat is provided with a second sliding groove, the fourth motor is located below the top seat, a base is provided on one side of the fourth motor, the upper end of the base is provided with a slider that passes through the second sliding groove and is slidably connected to the second sliding groove, a third motor is provided at one end of the top seat, and the output end of the third motor is provided with a threaded rod that passes through the slider and is threadedly connected to the slider.

[0014] Furthermore, the improvements of this utility model include the use of a cylinder for the lifting assembly, and the use of servo motors for the first motor, second motor, third motor, and fourth motor.

[0015] Place the solenoid valve housing to be polished on the upper end of the processing table, start the first motor to make the gear rotate, thereby causing the two gear plates to move towards each other, so that the two clamping seats clamp and fix the solenoid valve housing.

[0016] Start the lifting assembly to lower the grinding shaft and make it contact the inner wall of the solenoid valve housing. Start the fourth motor to make the grinding shaft rotate and grind the inner wall of the solenoid valve housing.

It is especially suitable for multi-specification, small-batch production scenarios.

[0021] The grinding assembly achieves adaptive processing of shells of different heights and diameters through a three-dimensional motion combination of "vertical lifting - radial adjustment - circumferential rotation".

[0028] 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.

[0029] Please see Figures 1-5 The present invention provides a positioning and clamping solenoid valve grinding device, including a processing table 1, a grinding component above the processing table 1, and two clamping components symmetrically arranged at the upper end of the processing table 1.

[0030] The clamping assembly includes a base 13, a first slide groove 14, and a clamping seat 17. A vertical rod 15 is vertically arranged in the middle part of the base 13, passing through the first slide groove 14. The vertical rod 15 is slidably connected to the first slide groove 14. A toothed plate 22 is provided at the bottom end of the vertical rod 15. A fixing frame 23 is provided at the lower end of the processing table 1. A first motor 24 is provided at the bottom end of the fixing frame 23. A gear 25 is provided at the output end of the first motor 24, located between the two toothed plates 22. The gear 25 meshes with the two toothed plates 22.

[0031] The upper end of the base 13 is provided with a positioning seat 16, and the positioning seat 16 is provided with a positioning groove. The outer side of the clamping seat 17 is provided with a positioning block 18 that is inserted into the positioning groove. The inner wall of the positioning groove is provided with a slot 21. The two sides of the positioning block 18 are provided with cavities 19. A spring is provided in the cavity 19. One end of the spring is provided with a locking block 20 that cooperates with the slot 21.

[0032] All of the aforementioned card blocks 20 are isosceles trapezoidal structures.

[0033] One end of the spring is fixed inside the cavity 19, and the other end is connected to the locking block 20.

[0034] The grinding assembly includes a lifting assembly 2, a top plate 3, a top seat 5, a second motor 4, and a fourth motor 11. The lifting assembly 2 is fixed to the upper end of the processing table 1. The top plate 3 is fixed to the output end of the lifting assembly 2. The second motor 4 is fixed to the lower end of the top plate 3. The top seat 5 is fixed to the output end of the second motor 4. The top seat 5 is provided with a second sliding groove 6. The fourth motor 11 is located below the top seat 5. A base 10 is provided on one side of the fourth motor 11. A slider 7 is provided at the upper end of the base 10, passing through the second sliding groove 6 and slidably connected to the second sliding groove 6. A third motor 9 is provided at one end of the top seat 5. A threaded rod 8 passing through the slider 7 is provided at the output end of the third motor 9. The threaded rod 8 is threadedly connected to the slider 7.

[0035] Workpiece clamping and mechanical locking:

[0036] Place the solenoid valve housing horizontally on the upper part of the processing table 1, start the bottom first motor 24, the gear 25 at the output end of the first motor 24 starts to rotate, and drives the toothed plates 22 on both sides to move inward synchronously through meshing transmission.

[0037] The vertical rod 15 extending upward from the toothed plate 22 slides within the first groove 14 of the base 13, pushing the clamping seat 17 toward the center of the housing, providing clamping and limiting function for the solenoid valve housing on the processing table 1, ensuring that the solenoid valve housing does not shift during the grinding process.

[0038] Three-dimensional positioning adjustment of grinding components:

[0039] Vertical positioning: Start the lifting assembly 2 (cylinder), and the top plate 3 at its output end drives the second motor 4, top seat 5 and grinding shaft 12 below to descend synchronously until the grinding shaft 12 fits against the inner wall of the solenoid valve housing opening.

[0040] Radial adjustment: Start the third motor 9 at one end of the top seat 5. The motor drives the threaded rod 8 to rotate. The threaded rod 8 passes through the slider 7 and is threadedly connected to it, so that the slider 7 slides laterally in the second slide groove 6 of the top seat 5. This drives the base 10 and the fourth motor 11 and grinding shaft 12 installed on the base 10 to complete the radial position adjustment, ensuring that the grinding shaft 12 maintains the preset working distance with the inner wall of the housing, and is convenient to adapt to solenoid valve housings of different diameters.

[0041] Automated grinding of the inner wall in all directions:

[0042] Grinding execution: Start the fourth motor 11 to drive the grinding shaft 12 to rotate at high speed. The abrasive on the outer wall of the grinding shaft 12 comes into contact with the inner wall of the housing, and the polishing operation begins.

[0043] Circumferential coverage: Simultaneously start the second motor 4, drive the top seat 5 to rotate around the vertical axis, so that the grinding shaft 12 moves at a constant speed along the circumference of the shell. In conjunction with the rotation of the grinding shaft 12, 360° grinding of the inner wall without dead angles can be achieved.

[0044] During the polishing process, the vertical height of the polishing shaft 12 can be finely adjusted by the lifting component 2 to control the uniformity of the polishing depth.

[0045] Clamping base 17 quick change and specification adaptation:

[0046] When it is necessary to process shells of different diameters, manually pull the clamping seat 17 outward. The locking block 20 is compressed by external force and retracts into the cavity 19, disengaging from the locking state of the slot 21, and the clamping seat 17 can be removed from the positioning seat 16.

[0047] When replacing the clamping seat 17 with one that fits the new diameter, align the positioning block 18 with the positioning slot and insert it. The locking block 20 will automatically engage with the slot 21 under the action of the spring force, completing the quick installation. Simultaneously repeat the radial adjustment steps, adjusting the position of the grinding shaft 12 with the third motor 9 to fit the new inner diameter of the housing, without the need to recalibrate the overall structure.

[0048] The upper end of the processing table 1 is provided with a guide rod 26 that passes through both ends of the base 13 and is slidably connected to the base 13.

[0049] The guide rod 26 runs through both ends of the base 13, providing rigid support for the clamping assembly and preventing tilting and swaying when the housing is clamped.

[0050] The lifting assembly 2 uses a cylinder, and the first motor 24, the second motor 4, the third motor 9 and the fourth motor 11 are all servo motors.

[0051] The servo motor precisely controls the rotational speed and circumferential movement trajectory of the grinding shaft 12, and in conjunction with the stable lifting and lowering of the cylinder, ensures a uniform and consistent surface finish on the inner wall. Even with thin-walled housings, the coordinated control of clamping force and grinding intensity prevents processing deformation and ensures the sealing of the valve body during subsequent installation.

[0052] The wear-resistant metal material of the clamping block 20 and the clamping slot 21, combined with the high fatigue life design of the spring, ensures that the clamping mechanism is not prone to failure during long-term use. The rust-proof chrome plating treatment on the surface of the guide rod 26 reduces sliding friction loss and lowers the frequency of maintenance. The symmetrical fixing structure of the double clamping base 17, combined with the rigid support of the grinding components, keeps the equipment in a low-vibration state when operating at high speed, extends the service life of each component, and improves the overall operational safety.
