Description

Technical Field

[0001] This utility model relates to the field of plunger processing technology, specifically a plunger dual-station alternating grinding platform. Background Technology

[0002] In modern industrial manufacturing, plungers are indispensable key components in many mechanical devices, and their machining quality plays a crucial role in the performance and reliability of the entire equipment. In particular, the end face machining of the plunger is a core factor affecting the precision of the plunger's fit with other components, its sealing performance, and its working efficiency.

[0003] Currently, most existing plunger grinding equipment is a single-station design, meaning it can only grind one plunger at a time. This type of single-station grinding equipment suffers from low production efficiency, especially when mass-producing plungers, as it requires a significant amount of time to grind each plunger individually, resulting in long production cycles and high production costs. Furthermore, single-station grinding equipment is idle when changing between plungers to be ground and those already ground, further reducing equipment utilization.

[0004] Therefore, it is necessary to provide a plunger dual-station alternating grinding platform to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a plunger dual-station alternating grinding platform to solve the problems mentioned in the background art.

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

[0007] A plunger dual-station alternating grinding platform, comprising:

[0008] The processing table has symmetrically distributed support feet fixedly installed on both sides of its bottom. The top of the processing table has a slide rail, and a threaded rod is rotatably installed inside the slide rail. A brake motor is fixedly installed above one side of the processing table, and the drive end of the brake motor passes through the processing table and extends into the interior of the slide rail, where it is fixedly connected to one end of the threaded rod.

[0009] An adjusting block is fitted on the outer wall of the threaded rod, and the adjusting block is slidably installed on the slide rail. A double-station slide is fixedly installed on the top of the adjusting block. A symmetrically distributed positioning groove is opened on the top of the double-station slide. A clamping mechanism is provided on the positioning groove. A fixing frame is fixedly installed on the rear side of the top of the processing table.

[0010] A second cylinder is fixedly installed on the top of the fixed frame, and the driving end of the second cylinder passes through the fixed frame and extends to the top of the processing table. A mounting plate is fixedly installed on the driving end of the second cylinder, and a grinding motor is fixedly installed on the bottom of the mounting plate. A grinding head is fixedly installed on the driving end of the grinding motor.

[0011] Preferably, limit rods are fixedly installed on both sides of the top of the mounting plate, and the top of the fixing frame is provided with sliding holes corresponding to the position and number of the limit rods, and the fixing frame is slidably connected to the limit rods through the sliding holes on its top.

[0012] Preferably, the clamping mechanism includes a hidden groove, and there are two hidden grooves. The two hidden grooves are symmetrically distributed on the inner wall of the positioning groove. The front and back of the dual-position slide are fixedly installed with symmetrically distributed first cylinders, and the positions of the first cylinders correspond to the positioning grooves. The driving end of the first cylinder passes through the dual-position slide and extends into the interior of the positioning groove. A clamp adapted to the hidden groove is fixedly installed on the driving end of the first cylinder.

[0013] Preferably, the adjusting block has a T-shaped structure, and a plurality of ball bearings are movably installed on the sliding contact surface between the adjusting block and the top of the processing table, and the ball bearings are in rolling contact with the top of the processing table.

[0014] Preferably, the adjusting block has a threaded hole that matches the threaded rod, and the adjusting block is threadedly connected to the threaded rod through the threaded hole.

[0015] Preferably, a reinforcing plate is fixedly installed at the corner inside the fixing frame.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model utilizes a processing table, slide rail, threaded rod, support foot, brake motor, fixture, first cylinder, positioning groove, dual-station slide, hidden groove, grinding head, grinding motor, fixing frame, mounting plate, second cylinder, and adjusting block in combination. By setting two positioning grooves on the dual-station slide, grinding can be performed at one station while the plunger to be ground is replaced and clamped at the other station. This achieves alternating grinding at two stations, effectively shortening the production cycle and significantly improving production efficiency.

[0018] 2. By setting a limiting rod, the limiting rod at the top of the mounting plate will contact the fixed frame during the vertical movement of the grinding motor and grinding head driven by the second cylinder. This contact structure effectively constrains the movement trajectory of the grinding motor and grinding head, which can significantly enhance the stability of the two during operation and reduce the adverse effects of vibration or offset on the grinding accuracy and quality.

[0019] 3. This invention utilizes ball bearings to create a rolling contact between the adjusting block and the top of the processing table as the adjusting block moves along the slide rail. This rolling contact ensures reliable contact between the adjusting block and the processing table, enhancing the stability of the dual-station slide during operation and ensuring the accuracy and reliability of its movement. Furthermore, the rolling contact significantly reduces friction between the adjusting block and the processing table, decreasing the resistance the brake motor needs to overcome when driving the adjusting block and thus improving its operating efficiency. In addition, compared to sliding contact, the rolling contact effectively reduces wear on the adjusting block, extends its service life, and lowers maintenance costs and replacement frequency.

[0029] Please see Figures 1-4 One embodiment provided by this utility model:

[0030] A plunger dual-station alternating grinding platform, comprising:

[0031] The processing table 1 has symmetrically distributed support feet 4 fixedly installed on both sides of the bottom of the processing table 1. The top of the processing table 1 has a slide rail 2. A threaded rod 3 is rotatably installed inside the slide rail 2.

The drive end of the brake motor 5 passes through the processing table 1 and extends into the interior of the slide rail 2 and is fixedly connected to one end of the threaded rod 3.

[0032] An adjusting block 17 is fitted on the outer wall of the threaded rod 3, and the adjusting block 17 is slidably installed on the slide rail 2. A double-station slide table 9 is fixedly installed on the top of the adjusting block 17. A symmetrically distributed positioning groove 8 is opened on the top of the double-station slide table 9. A clamping mechanism is provided on the positioning groove 8. A fixed frame 13 is fixedly installed on the rear side of the top of the processing table 1.

[0033] A second cylinder 16 is fixedly installed on the top of the fixed frame 13, and the driving end of the second cylinder 16 passes through the fixed frame 13 and extends to the top of the processing table 1. A mounting plate 14 is fixedly installed on the driving end of the second cylinder 16, and a grinding motor 12 is fixedly installed on the bottom of the mounting plate 14. A grinding head 11 is fixedly installed on the driving end of the grinding motor 12.

[0034] Limiting rods 15 are fixedly installed on both sides of the top of the mounting plate 14. The top of the fixing frame 13 is provided with sliding holes corresponding to the position and number of the limiting rods 15, and the fixing frame 13 is slidably connected to the limiting rods 15 through the sliding holes on its top.

[0035] In one embodiment, the clamping mechanism includes a hidden groove 10, and there are two hidden grooves 10. The two hidden grooves 10 are symmetrically distributed on the inner wall of the positioning groove 8. The front and back of the dual-position slide table 9 are fixedly installed with symmetrically distributed first cylinders 7, and the position of the first cylinders 7 corresponds to the positioning groove 8. The driving end of the first cylinder 7 passes through the dual-position slide table 9 and extends into the interior of the positioning groove 8. A clamp 6 adapted to the hidden groove 10 is fixedly installed on the driving end of the first cylinder 7.

[0036] In one preferred embodiment, the adjusting block 17 is T-shaped, and a plurality of balls 19 are movably mounted on the sliding contact surface between the adjusting block 17 and the top of the processing table 1, and the balls 19 are in rolling contact with the top of the processing table 1.

[0037] In one embodiment, the adjusting block 17 has a threaded hole that matches the threaded rod 3, and the adjusting block 17 is threadedly connected to the threaded rod 3 through the threaded hole.

[0038] In one preferred embodiment, a reinforcing plate 18 is fixedly installed at the corner inside the fixing frame 13, which can enhance the structural strength and stability of the fixing frame 13, enabling it to better withstand the stress and vibration during grinding operations and extend its service life.

[0039] The working principle of this utility model is as follows: The entire device is controlled by a main control button. Since the equipment matched with the control button is common equipment and belongs to existing common knowledge technology, its electrical connection relationship and specific circuit structure will not be described in detail here. The parts of this device not mentioned are the same as or can be implemented using existing technology. In use, the plungers to be processed are first placed in the two positioning slots 8 respectively. Then, the two first cylinders 7 on each positioning slot 8 are simultaneously controlled to move. The driving end of the first cylinder 7 pushes the clamp 6 out of the hidden slot 10 and moves into the positioning slot 8. The two clamps 6 in the positioning slot 8 move relative to each other under the drive of the first cylinder 7, thereby clamping and fixing the plungers to be processed. After that, the brake motor 5 is started. The driving end of the brake motor 5 drives the threaded rod 3 to rotate. Utilizing the threaded transmission between the threaded rod 3 and the adjusting block 17, combined with the sliding cooperation between the adjusting block 17 and the slide rail 2, the adjusting block 17 moves stably along the direction of the slide rail 2. The movement of the adjusting block 17 drives the double-station slide 9 to move, thereby causing the two plungers fixed on the double-station slide 9 to move accordingly. First, move the left plunger below the grinding head 11, and simultaneously start the second cylinder 16 and the grinding motor 12. The grinding motor 12 drives the grinding head 11 to rotate, and the second cylinder 16 drives the mounting plate 14 to move vertically. The movement of the mounting plate 14 causes the grinding motor 12 and the grinding head 11 to move synchronously. Driven by the second cylinder 16, the rotating grinding head 11 descends and contacts the end face of the plunger, thus achieving the grinding process on the plunger. After the left plunger has been processed, continue to control the movement of the dual-station slide 9, so that the right plunger moves below the grinding head 11 for processing. At this time, the worker can remove the processed left plunger and install a new plunger to be processed. Through the setting of the two positioning slots 8 on the dual-station slide 9, grinding can be performed at one station while the plunger to be ground is replaced at the other station.

[0040] During use, as the second cylinder 16 drives the grinding motor 12 and the grinding head 11 to move vertically, the limiting rod 15 on the top of the mounting plate 14 will contact the fixing frame 13. This contact structure effectively constrains the movement trajectory of the grinding motor 12 and the grinding head 11, which can significantly enhance the stability of the two during operation and reduce the adverse effects of vibration or offset on the grinding accuracy and quality.

[0041] In use, as the adjusting block 17 moves along the slide rail 2, the contact portion between the adjusting block 17 and the top of the processing table 1 forms a rolling contact with the bottom of the processing table 1 via the ball bearings 19. This rolling contact method ensures reliable contact between the adjusting block 17 and the processing table 1, enhancing the stability of the dual-position slide table 9 during operation and ensuring the accuracy and reliability of its movement. Furthermore, the rolling contact significantly reduces the friction between the adjusting block 17 and the processing table 1, reducing the resistance that the brake motor 5 needs to overcome when driving the adjusting block 17, thereby improving the operating efficiency of the brake motor 5. In addition, compared to sliding contact, the rolling contact method effectively reduces the wear of the adjusting block 17, extends its service life, and lowers the equipment's maintenance costs and replacement frequency.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
