Description

Technical Field

[0001] This utility model relates to the field of vortex machine partition plate processing technology, and in particular to a vortex machine partition plate processing device. Background Technology

[0002] In modern industry, scroll compressors, with their unique scroll principle, are widely used in many scenarios such as air conditioning and refrigeration, air compression, and fluid transportation, becoming an indispensable key piece of equipment. Scroll compressors achieve functions such as compression, pumping, or mixing through the meshing motion of two scroll-shaped components, and have many advantages such as compact structure, high efficiency, and low vibration.

[0003] However, scroll compressors have a significant problem when shutting down. When the compressor stops working, the compressed high-pressure gas can easily flow back into the compression chamber, causing the pump to reverse and the motor to reverse as well, resulting in considerable noise that seriously affects the normal operation of the equipment and the surrounding environment. To solve this noise problem, existing technology typically involves installing a partition plate at the upper end of the stationary scroll plate of the scroll compressor, dividing the compressor into a high-pressure exhaust chamber and a low-pressure intake chamber. This prevents the backflow of high-pressure gas from causing the motor and pump to reverse and generating noise.

[0004] However, currently, the ventilation holes (opposite to the static scroll plate shaft hole) of the partition plate and the mounting holes for installing the check valve are often processed manually. This method is not only inefficient, but also makes it difficult to ensure the uniformity of product quality, affecting the stability and reliability of the overall performance of the scroll compressor. Utility Model Content

[0005] To address the shortcomings of the aforementioned background technology, this utility model provides a vortex machine partition plate processing device, which can improve the processing efficiency and quality of partition plates.

[0006] The technical implementation scheme of this utility model is as follows: a vortex machine partition plate processing device, including a base, a drill bit and a clamp set on the base, the drill bit including a drill body with a drill bit and a cylinder for driving the drill body to move vertically, the clamp including a horizontal slide rail set on the upper end of the base, two opposing clamping plates slidably set on the horizontal slide rail, the two clamping plates are respectively hinged to a connecting rod, the ends of the two connecting rods away from the clamping plates are jointly hinged to a moving block, the moving block is slidably connected to the base, and the upper end surface of the moving block is provided with an inclined groove, wherein the end of the inclined groove near the clamping plate is the lower end, the top of the inclined groove is provided with a vertical rod, the upper end of the vertical rod is connected to the cylinder and rises and falls synchronously with the cylinder, the vertical rod drives the moving block to move in a direction perpendicular to the horizontal slide rail through the inclined groove.

[0007] More preferably, a tension spring is connected between the movable block and the base, the tension spring being arranged in the same direction as the moving direction of the movable block, and the tension spring pulling the movable block closer to the clamping plate.

[0008] More preferably, a limit baffle is provided at the top of the moving block near the high end of the inclined groove.

[0009] More preferably, anti-slip protrusions are provided on the opposite sides of the two clamps.

[0010] More preferably, a sleeve is provided between the vertical rod and the movable rod of the cylinder, the sleeve is sleeved on the vertical rod, and multiple pin holes are provided on the sleeve and the vertical rod at intervals along their length directions.

[0011] More preferably, a long groove is formed in the middle of the upper surface of the base, and the bottom surface of the long groove is inclined.

[0012] More preferably, the drilling rig body includes a housing, the bottom of which is provided with a chuck for mounting a drill bit, and the inside of the housing is provided with a motor for driving the chuck to rotate. The chuck includes a central chuck and two side chucks, which are symmetrical about the central chuck. A limit ring is provided on the outer side of the chuck, and the limit ring is connected to the bottom of the housing through multiple telescopic rods. A first contact piece is provided on the telescopic rod, and a second contact piece is provided on the limit ring. The first and second contact pieces are electrically connected to the controller of the cylinder, respectively. When the telescopic rod retracts, the first and second contact pieces contact each other to limit the stroke of the cylinder.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. This utility model uses a cylinder in the drill bit to drive the drill body to move vertically, which can accurately process ventilation holes and one-way valve mounting holes on the partition plate. Utilizing the structure of the vertical rod and inclined groove, it simultaneously drives the moving block to move. Through the action of the connecting rod, it drives the two clamping plates on the horizontal slide rail to move synchronously towards each other, so that the clamp can realize the action of clamping the drill hole and releasing and resetting under the drive of the cylinder, thereby improving the automation and processing efficiency of the device.

[0015] 2. This utility model connects a tension spring between the moving block and the base, so that after processing, the tension spring acts on the moving block to move it toward the position of the clamping plate, which can automatically release the partition plate and unload the material.

[0016] 3. This utility model effectively limits the maximum travel of the moving block by setting a limiting baffle. This, in turn, limits the spacing of the clamping plates and the direction of subsequent continuous processing.

[0017] 4. This utility model significantly increases the friction between the clamping plates and the partition plate by setting anti-slip protrusions on opposite sides of the two clamping plates. During processing, the partition plate is subjected to the force of the drill bit, which can easily cause relative sliding. The anti-slip protrusions effectively prevent the partition plate from slipping off due to external forces while clamped, ensuring that the partition plate remains in a stable clamped state during processing, thus improving processing accuracy and product quality.

[0018] 5. By setting a sleeve and pin hole between the vertical rod and the cylinder moving rod, the relative position between the vertical rod and the cylinder moving rod can be flexibly adjusted by inserting the pin into different pin holes, thereby adjusting the clamping force and stroke of the fixture. The fixture can be quickly adjusted according to the size of the partition plate or processing requirements, enhancing the versatility and adaptability of the device.

[0019] 6. This utility model has an inclined long groove in the middle of the upper surface of the base, which facilitates the collection of debris during the processing.

[0020] 7. This utility model uses a limiting ring and first and second contact plates to limit the stroke of the cylinder. This achieves precise control of the drill bit, ensuring that the drill bit is at a reasonable depth when machining vent holes and mounting holes, further improving machining accuracy.

[0029] 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.

[0030] The vortex machine partition plate processing device provided in this embodiment, such as Figure 1-7 As shown, the system consists of a base 1, a drill bit 2, and a clamp 3. The drill bit 2 includes a drill body 22 and a cylinder 23. The drill body 22 is equipped with a drill bit 21. The cylinder 23 is used to drive the drill body 22 to move vertically. The clamp 3 consists of a horizontal slide rail 31, two clamping plates 32, a connecting rod 33, and a moving block 34. The two clamping plates 32 are mounted on the horizontal slide rail 31 at the upper end of the base 1 and can slide along the slide rail. Each clamping plate 32 is hinged to one end of a connecting rod 33. The other ends of the two connecting rods 33 are hinged to the moving block 34. The moving block 34 can slide on the base 1 in a direction perpendicular to the horizontal slide rail 31. The upper end surface of the moving block 34 is machined with a slanted groove 341. The end of the slanted groove 341 near the clamping plate 32 is the lower end. A vertical rod 35 is set at the top of the slanted groove 341. The upper end of the vertical rod 35 is connected to the cylinder 23 to realize synchronous lifting and lowering action. The lower end can extend into the lower groove 341 to drive the moving block 34 to move.

[0031] refer to Figure 3In a preferred embodiment, a tension spring 4 is installed between the movable block 34 and the base 1. The arrangement direction of the tension spring 4 is consistent with the moving direction of the movable block 34, and its function is to continuously pull the movable block 34 towards the clamping plate 32. In this way, after processing is completed, the tension spring 4 can automatically pull the movable block 34, causing the clamping plate 32 to loosen the partition plate, thereby enabling the unloading operation. Furthermore, a limiting baffle 342 is added to the top of the movable block 34 near the high end of the inclined groove 341, and the bottom of the inclined groove 341 penetrates the movable block 34, with the diameter of the penetration portion being larger than the diameter of the vertical rod 35. When the moving block 34 moves towards the clamping plate 32 under the action of the tension spring 4, the clamping plate 32 releases the partition plate. To ensure that the vertical rod 35 can still drive the moving block 34 to move during the next processing, a limiting baffle 342 is set. After the moving block 34 is pulled to a certain position by the tension spring, the limiting baffle 342 abuts against the vertical rod 35 to block the moving block 34. When the vertical rod 35 moves downward with the cylinder 23, it moves along the limiting baffle 342 into the inclined groove 341. The two move relative to each other, and the lower end of the vertical rod 35 moves from the high end of the inclined groove 341 to the low end of the inclined groove 341. Through the movement of the moving block 34, the two connecting rods 33 pull the two clamping plates 32 to move towards each other, thereby achieving the clamping of the partition plate.

[0032] However, as the cylinder continues to descend, the vertical rod 35 will also drive the moving block 34 to continue moving through the inclined groove 341. This will cause the clamping force of the clamping plate 32 to hold the partition plate to increase, which may damage the clamping plate 23 or the partition plate. Therefore, the bottom of the inclined groove 341 passes through the moving block 34. After the clamping plate 32 approaches the appropriate position, the vertical rod 35 passes through the bottom of the inclined groove 341. At this time, the vertical rod 35 and the moving block 34 no longer move relative to each other. Even if the cylinder 23 continues to move down to drive the drilling machine body 22 to perform drilling, the clamping plate 32 maintains the appropriate clamping force and remains stationary.

[0033] refer to Figure 3 In a preferred embodiment, a sleeve 6 is provided between the vertical rod 35 and the movable rod of the cylinder 23. The sleeve 6 is fitted onto the vertical rod 35, and pin holes 7 are respectively provided on the sleeve 6 and the vertical rod 35. The pin holes 7 on the sleeve 6 and the vertical rod 35 are evenly distributed along their length. By inserting pins into different pin holes 7, the relative position between the vertical rod 35 and the inclined groove 341 can be flexibly adjusted. By changing the stroke of the moving block 34, the clamping force of the fixture 3 can be changed, thus meeting the processing requirements of partition plates of different specifications and enhancing the versatility of the device.

[0034] The drilling rig body 22 described in this embodiment has the following structure: Figure 2 and Figure 4As shown, the bottom of the housing 221 is equipped with a chuck, which consists of a central chuck 222 and two symmetrically distributed side chucks 223. An external limiting ring 8 is provided, connected to the bottom of the housing 221 via a telescopic rod 81. A first contact piece 82 is mounted on the telescopic rod 81, and a corresponding second contact piece 83 is provided on the limiting ring 8. Both are electrically connected to the controller of the cylinder 23. When the telescopic rod 81 retracts, and the first contact piece 82 contacts the second contact piece 83, the stroke of the cylinder 23 is limited, achieving precise control of the machining depth of the drill bit 21. This ensures the machining accuracy of the vent hole and mounting hole, and avoids over-drilling that could damage the partition plate.

[0035] Specifically, a vertical plate 24 is erected on the rear side of the upper end face of the base 1. A vertical slide rail and a slider are installed on the vertical plate 24. The drilling machine body 22 is installed on the slider. The cylinder 23 is fixed on the vertical plate 24 with its front end facing down. A vertical slot is opened on the vertical plate 24 to accommodate the matching rod 6.

[0036] refer to Figure 5 Multiple telescopic rods 81 can be provided. Each telescopic rod 81 consists of a thin rod 811 and an outer tube 812. The thin rod 811 is slidably fitted into a groove at the bottom of the outer tube 812. A spring 84 is provided between the bottom of the thin rod 811 and the outer tube 812 to facilitate the return of the thin rod 811 to its original position. A limiting groove 814 is provided on the side of the groove. Multiple adjusting holes 813 are distributed along the length of the side of the thin rod 811. A pin can be inserted into the adjusting holes 813 at different positions. By using the cooperation between the pin and the limiting groove 814, the extension stroke of the thin rod 811 can be adjusted, that is, the extension length of the thin rod 811 can be adjusted.

[0037] During drilling, when the drill body 22 approaches the partition plate, the limiting ring 8 abuts against the partition plate and compresses the telescopic rod 81, causing the first contact piece 82 to contact the second contact piece 83. At this point, the cylinder 23 stops descending, and the drilling depth reaches the preset value. In particular, for blind hole mounting holes used to install one-way valves, this depth control design can effectively prevent drilling through the partition plate and avoid the risk of air leakage.

[0038] In another preferred embodiment, anti-slip protrusions 5 are provided on opposite sides of the two clamping plates 32 to increase the friction between the clamping plates 32 and the partition plate, prevent the partition plate from slipping due to force during drilling, and ensure the stability and accuracy of the processing.

[0039] like Figure 1 As shown, a long groove 11 is machined in the middle of the upper end face of the base 1. The bottom surface of the long groove 11 is inclined, which facilitates the smooth falling and collection of debris generated during the processing, keeping the working environment clean, and preventing debris from interfering with the processing.

[0040] like Figure 6The diagram shows the working state of the vortex machine partition plate processing device. The upper surface of the base 1 has a boss to prevent partition plate A from being placed between clamping plates 32. In a preferred embodiment, partition plate A is a disc structure with a central opening for a vent A1. A one-way valve mounting hole A2 is located outside the vent A1. The one-way valve mounting hole A2 is a blind hole and can be machined into a threaded hole. A flange is formed on the side of partition plate A for connecting to the vortex machine housing. During actual operation, the drilling machine body 22 is driven vertically by cylinder 23 to precisely process the vent A1 and one-way valve mounting hole A2 on partition plate A. Simultaneously, the vertical rod 35 and the inclined groove 341 work together to move the moving block 34. Through the connecting rod 33, the two clamping plates 32 on the horizontal slide rail 31 move synchronously towards each other, thereby achieving automatic clamping and releasing of the fixture, greatly improving the automation level and processing efficiency of the device.

[0041] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the inventive concept, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
