Description

Technical Field

[0001] This utility model relates to the field of milling fixture technology, and in particular to a high-efficiency screw vacuum pump rotor milling fixture. Background Technology

[0002] A screw pump rotor milling machine is a device used to process screw pump rotors. Through mechanical locking, the accuracy of workpiece processing can be guaranteed, and the clamping efficiency can be increased by more than 30%. It is suitable for batch processing.

[0003] Currently, when clamping and fixing rotor blanks, the required dimensions of rotors vary, resulting in different dimensions of rotor blanks. This means that the rotor blanks need to be clamped in suitable fixtures during the clamping process, leading to low clamping fit and poor clamping effect.

[0004] Meanwhile, during the clamping and processing of the rotor blank, a large amount of debris and oil stains tend to accumulate when the clamp slides, which can increase friction and cause jamming at the sliding point of the clamp.

[0005] Therefore, we propose a high-efficiency screw vacuum pump rotor milling fixture to solve the problems mentioned above. Utility Model Content

[0006] By utilizing the longitudinal and lateral movement of the adjusting plate, it can be clamped according to the diameter of the rotor blank. When the adjusting plate is stretched or compressed longitudinally or laterally, the telescopic plate can improve the stability of the adjusting plate's movement. At the same time, the cleaning brush and scraper can scrape and clean the debris remaining at the sliding part of the sliding seat and guide rail plate, thereby preventing the sliding seat from getting stuck during movement, thus solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: including a clamp, a fixing mechanism and a cleaning mechanism, wherein the fixing mechanism includes a telescopic plate and an adjusting plate, the adjusting plate is installed on the telescopic surface of the telescopic plate, and the adjusting plate and the telescopic plate are used to adjust according to the diameter of the rotor blank, thereby improving the clamping stability of the rotor blank.

[0008] The cleaning mechanism includes a cleaning brush and a scraper. The scraper is located to the right of the cleaning brush. The scraper and the cleaning brush are used to clean debris from the sliding part of the clamp to prevent the clamp from getting stuck when moving.

[0009] Preferably, the fixing mechanism further includes a pressing seat, the rear surface of which is movably connected to the front surface of the adjusting plate via a bearing, and the front surface of the pressing seat is provided with a rubber pad.

[0010] Preferably, the cleaning mechanism further includes a horizontal plate, the lower surface of which is fixedly connected to the upper surface of the cleaning brush and scraper, and a hollow tube is fixedly connected to the lower surface of the scraper, with ball bearings movably connected inside the hollow tube.

[0011] Preferably, the clamp has a sliding plate internally connected to it, a clamping ring fixedly connected to the lower surface of the sliding plate, a friction seat provided on the inner wall of the clamping ring, a connecting plate fitted to the lower surface of the clamping ring, and the front surface of the connecting plate being movably connected to the telescopic plate via a bearing. The front surface of the connecting plate is fixedly connected to the rear surface of the telescopic plate, and both the lower and upper surfaces of the clamping ring are movably connected to an adjusting plate via bearings.

[0012] Preferably, a limiting plate extends through the interior of the movable plate, and a threaded rod is threadedly connected to the interior of the limiting plate, with the bottom end of the threaded rod connected to the internal thread of the clamp.

[0013] Preferably, a sliding seat is fixedly connected to the lower surface of the clamp, and the interior of the sliding seat is fixedly connected to the horizontal plate. A guide rail plate is slidably connected to the lower surface of the sliding seat, and the interior of the guide rail plate is slidably connected to the cleaning brush and scraper.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, the moving plate is moved downward according to the diameter of the rotor blank, so that the spacing between the clamping rings can be adjusted. When the clamping rings move, the connecting plate can slide and retract inside the two sets of clamping rings. According to the adjustment of the clamping ring spacing, the clamping rings can push the adjusting plate to move and squeeze. The adjusting plate can be pushed laterally to move the squeezing seat under the squeezing effect, so that the squeezing seat can drive the rubber pad to fit against the surface of the rotor blank. When the adjusting plate moves, the telescopic plate can extend and retract according to the movement of the adjusting plate to support the adjusting plate. In conjunction with the adjustment of the clamping ring spacing, it can be adjusted according to the diameter of the rotor blank, and at the same time, the stability of the rotor blank during clamping can be improved.

[0016] 2. In this utility model, when the sliding seat slides inside the guide rail plate, the ball bearings are affected by friction and can roll according to the movement of the sliding seat, which can improve the movement efficiency of the sliding seat. During the movement, the sliding seat can drive the ball bearings to roll and also drive the cleaning brush and scraper to move at the sliding point between the sliding seat and the guide rail plate. The movement of the scraper can scrape and clean the residual debris and oil stains at the sliding point, and the cleaning brush can perform secondary cleaning of the residue cleaned by the scraper. This can prevent the clamp from getting stuck due to the accumulation of debris and oil stains at the sliding point when it moves. Attached Figure Description

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention can also be implemented in other ways than those described herein, and therefore the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1, as shown in the attached document Figure 1 - Figure 4 As shown, it includes a clamp 4, a fixing mechanism 10 and a cleaning mechanism 14. The fixing mechanism 10 includes a telescopic plate 104 and an adjusting plate 101. The adjusting plate 101 is installed on the telescopic surface of the telescopic plate 104. The adjusting plate 101 and the telescopic plate 104 are used to adjust according to the diameter of the rotor blank, which improves the clamping stability of the rotor blank.

[0025] The cleaning mechanism 14 includes a cleaning brush 142 and a scraper 143. The scraper 143 is located to the right of the cleaning brush 142. The scraper 143 and the cleaning brush 142 are used to clean the debris at the sliding part of the clamp 4 to prevent the clamp 4 from getting stuck when moving.

[0026] The overall effect of embodiment 1 is as follows: the longitudinal and transverse movements of the adjusting plate 101 allow it to be clamped according to the diameter of the rotor blank. When the adjusting plate 101 is stretched or compressed in the longitudinal or transverse direction, the telescopic plate 104 can improve the stability of the adjusting plate 101. At the same time, the cleaning brush 142 and the scraper 143 can scrape and clean the debris remaining at the sliding part of the sliding seat 8 and the guide rail plate 2, thereby preventing the sliding seat 8 from getting stuck during movement.

[0027] Example 2, as Figure 1 and Figure 4 As shown, the fixing mechanism 10 also includes a pressing seat 102. The rear surface of the pressing seat 102 is movably connected to the front surface of the adjusting plate 101 via a bearing. A rubber pad 103 is provided on the front surface of the pressing seat 102. A moving plate 6 is slidably connected inside the clamp 4. A clamping ring 3 is fixedly connected to the lower surface of the moving plate 6. A friction seat 9 is provided on the inner wall of the clamping ring 3. A connecting plate 11 is fitted to the lower surface of the clamping ring 3. The front surface of the connecting plate 11 is movably connected to the telescopic plate 104 via a bearing. The front surface of the connecting plate 11 is fixedly connected to the rear surface of the telescopic plate 104. The lower and upper surfaces of the clamping ring 3 are both movably connected to the adjusting plate 101 via bearings. A limiting plate 12 passes through the interior of the moving plate 6. A threaded rod 13 is threadedly connected inside the limiting plate 12. The bottom end of the threaded rod 13 is threadedly connected to the interior of the clamp 4.

[0028] The overall effect achieved in Embodiment 2 is as follows: Based on the diameter of the rotor blank, the moving plate 6 is moved downwards, allowing adjustment of the spacing between the clamping rings 3. When the clamping rings 3 move, the connecting plate 11 can slide and retract inside the two sets of clamping rings 3. According to the adjustment of the spacing between the clamping rings 3, the clamping rings 3 can push the adjusting plate 101 to move and compress. Under the influence of compression, the adjusting plate 101 can laterally push the compression seat 102 to move, allowing the compression seat 102 to drive the rubber pad 103 to adhere to the surface of the rotor blank. When the adjusting plate 101 moves... When in motion, the telescopic plate 104 can extend and retract to support the adjusting plate 101 according to its movement. In conjunction with the adjustment of the spacing of the clamping rings 3, it can be adjusted according to the diameter of the rotor blank, which can also improve the stability of the rotor blank when clamped. After the clamping rings 3 and the extrusion seat 102 are in contact with the two end surfaces of the rotor blank, the limiting plate 12 is inserted into the designated position of the moving plate 6. Tightening the threaded rod 13 can fix the limiting plate 12, so that the clamping rings 3 and the extrusion seat 102 can clamp and fix the two ends of the rotor blank.

[0029] Example 3, as Figure 1 - Figure 3 The cleaning mechanism 14 also includes a horizontal plate 141. The lower surface of the horizontal plate 141 is fixedly connected to the upper surface of the cleaning brush 142 and the scraper 143. A hollow tube 145 is fixedly connected to the lower surface of the scraper 143. A ball bearing 144 is movably connected inside the hollow tube 145.

[0030] The effect achieved by the entire embodiment 3 is as follows: When the sliding seat 8 moves, the ball bearing 144 is in contact with the sliding part of the sliding seat 8, so that when the sliding seat 8 slides inside the guide rail plate 2, the ball bearing 144 can roll according to the movement of the sliding seat 8 due to friction, which can improve the movement efficiency of the sliding seat 8. During the movement of the sliding seat 8, while driving the ball bearing 144 to roll, it can also drive the cleaning brush 142 and the scraper 143 to move at the sliding part between the sliding seat 8 and the guide rail plate 2. The movement of the scraper 143 can scrape and clean the residual debris and oil stains at the sliding part, and the cleaning brush 142 can perform secondary cleaning of the residue scraped by the scraper 143, thereby preventing the clamp 4 from getting stuck due to the accumulation of debris and oil stains at the sliding part when it moves.

[0031] Example 4, as Figure 1 As shown, a sliding seat 8 is fixedly connected to the lower surface of the clamp 4, and the interior of the sliding seat 8 is fixedly connected to the horizontal plate 141. A guide rail plate 2 is slidably connected to the lower surface of the sliding seat 8, and the interior of the guide rail plate 2 is slidably connected to the cleaning brush 142 and the scraper 143. A base 1 is fixedly connected to the lower surface of the guide rail plate 2. Fixed seats 5 are fixedly connected to both the front and rear surfaces of the sliding seat 8. A limit rod 7 is slidably connected inside the fixed seat 5, and the limit rod 7 is fitted and connected to the base 1.

[0032] The effect achieved by the entire embodiment 4 is as follows: the rotor blank is placed between the two sets of clamps 4. Since the sliding seat 8 is concave and the guide rail plate 2 is I-shaped, the concave part of the sliding seat 8 can fit with the upper surface of the guide rail plate 2, and the protrusion can fit into the concave part of the guide rail plate 2, so that the sliding seat 8 can slide on the surface of the guide rail plate 2. By using the sliding of the sliding seat 8 and the guide rail plate 2, the distance between the two sets of clamps 4 can be adjusted according to the length of the rotor blank, so that both ends of the rotor blank can pass through the inside of the clamping ring 3 for clamping and fixing. The limiting rod 7 passes through the fixing seat 5 and extends into the inside of the base 1 to fix the clamp 4, thereby processing the rotor blank.

[0033] The working principle of the entire equipment is as follows: the rotor blank is placed between two sets of clamps 4. By sliding the sliding seat 8 and the guide rail plate 2, the distance between the two sets of clamps 4 can be adjusted according to the length of the rotor blank, so that both ends of the rotor blank can pass through the inside of the clamping ring 3 for clamping and fixing. The limiting rod 7 passes through the fixing seat 5 and extends into the inside of the base 1 to fix the clamps 4. When the sliding seat 8 moves, the ball is affected by friction and can roll according to the movement of the sliding seat 8. During the movement of the sliding seat 8, while driving the ball 144 to roll, it can also drive the cleaning brush 142 and the scraper 143 to move at the sliding point between the sliding seat 8 and the guide rail plate 2. The movement of the scraper 143 can scrape and clean the residual debris and oil stains at the sliding point, and the cleaning brush 142 can perform secondary cleaning on the residue scraped by the scraper 143.

[0034] The movable plate 6 is moved downwards to adjust the spacing between the clamping rings 3. When the clamping rings 3 move, the connecting plate 11 can slide and retract inside the two sets of clamping rings 3. According to the adjustment of the spacing between the clamping rings 3, the clamping rings 3 can push the adjusting plate 101 to move and squeeze. The adjusting plate 101 can be pushed laterally to move the squeezing seat 102 under the squeezing effect, so that the squeezing seat 102 can drive the rubber pad 103 to fit against the surface of the rotor blank. The limiting plate 12 is inserted into the designated position of the movable plate 6. The limiting plate 12 can be fixed by turning the threaded rod 13, and the rotor blank can be processed.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
