Description

Technical Field

[0001] This utility model relates to the field of air compressor processing equipment technology, and more specifically to a tooling fixture for milling grooves in a stationary vortex disc. Background Technology

[0002] Air compressors are the main component of air supply devices and are widely used in industrial production. Oil-free scroll air compressors provide clean, oil-free compressed air and are a promising new type of air compressor.

[0003] This air compressor head generally includes a moving scroll and a stationary scroll. The stationary scroll needs to have a scroll-shaped groove machined on it using a milling machine. The existing method is to use bolts to fix multiple pressure blocks on the machining platform of the milling machine to press and fix the stationary scroll. This method is troublesome to install and disassemble. Moreover, after each installation, it is necessary to ensure that the position of the stationary scroll is accurately pressed. Otherwise, the position of the milling cutter needs to be changed during subsequent milling, that is, the tool needs to be re-set, which greatly reduces the processing efficiency.

[0004] Meanwhile, existing stationary scroll plates are generally installed below or around the milling cutter, which makes them prone to damage from the milling cutter. They also have limited installation space and are inconvenient to install. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a tooling fixture for milling grooves with a stationary volute. It can be partially fixed on the processing platform of the milling machine and located below the milling cutter, while the other half extends out of the platform and is fixed on an externally installed frame. The stationary volute can be firmly fixed by rotating the clamping block of the clamping cylinder, which is convenient for assembly and disassembly. It has high processing efficiency and good results.

[0006] The solution of this utility model to the aforementioned technical problem is:

[0007] A tooling fixture for milling grooves on a static vortex disc includes a fixed base. The front and rear parts of the top surface of the top plate of the fixed base are fixed with transverse guide rails. A clamping moving plate is located above the two transverse guide rails. The front and rear parts of the bottom surface of the clamping moving plate are fixed with multiple sliders, which are inserted into the corresponding transverse guide rails.

[0008] The top surface of the clamping moving plate is filled with a stationary vortex plate to be processed. Rotary clamping cylinders are fixed on the top surface of the clamping moving plate at the left, right, front and rear of the stationary vortex plate. The pressure block fixed at the bottom of the end of the rotating pressure arm of the rotary clamping cylinder presses against the top surface of the corresponding side of the stationary vortex plate.

[0009] A lateral moving mechanism is fixed on the fixed base, which drives the clamping moving plate to move left and right.

[0010] The clamping moving plate has four right-angle bent limiting blocks fixed in the middle. The four corners of the bottom end of the stationary vortex disk are inserted into the right-angle grooves of the corresponding limiting blocks. The side walls of the four corners of the bottom end of the stationary vortex disk are tightly attached to the inner side walls of the corresponding right-angle grooves and cooperate with each other.

[0011] The top surface of the top plate of the fixed base has a through groove extending to the left and right in the middle. The lateral moving mechanism includes a fixed plate on the bottom surface of the top plate of the fixed base fixed at the left and right ends of the through groove. The two ends of the left and right extending moving screw are movably connected to the two fixed plates through bearings. A moving servo motor is fixed on one of the fixed plates. The output shaft of the moving servo motor is a spline shaft, which is inserted into the spline hole at one end of the moving screw and drives the moving screw to rotate. The moving block is screwed on the moving screw. The upper part of the moving block extends out of the through groove and is fixed on the bottom surface of the middle part of the clamping moving plate 20.

[0012] Connecting blocks are fixed on both the left and right ends of the through slot. A proximity sensor and a positioning block are fixed on each connecting block. A wear-resistant anti-collision block is fixed on the end face of the positioning block. The left and right ends of the moving block correspond to the sensing ends of the proximity sensors and the wear-resistant anti-collision blocks.

[0013] Support blocks are fixed on the top surface of the clamping movable plate below the middle of the upper part of the left and right sides of the stationary vortex disk. An adjustment screw hole is formed in the middle of the top surface of the support block. An adjustment stud is screwed into the adjustment screw hole. The top of the adjustment stud extends out of the top surface of the support block and forms or fixes a horizontal support block. The top surface of the horizontal support block is close to the bottom middle of the left or right extension of the stationary vortex disk.

[0014] A locking nut is screwed onto the upper part of the adjusting stud, and the bottom surface of the locking nut presses against the top surface of the support block.

[0015] The outstanding effect of this utility model is:

[0016] It can be partially fixed on the machining platform of the milling machine and located below the milling cutter, while the other half extends out of the platform and is fixed on the externally mounted frame. Its stationary scroll only needs to be clamped and fixed by rotating the clamping block of the hydraulic cylinder to achieve a firm fixation. Moreover, after the first tool setting, there is no need for subsequent tool setting, which makes its installation and positioning accurate and effective. Furthermore, its installation and disassembly can both be carried out outside the machining platform, which provides a large operating space and makes it easy to assemble and disassemble, ultimately improving machining efficiency and producing good machining results.

[0018] Figure 2 This is a partial sectional view of the present invention. Detailed Implementation

[0019] For example, see below. Figures 1 to 2 As shown, a tooling fixture for milling grooves on a static vortex disc includes a fixed base 10. The left part of the fixed base 10 is fixed to the machining platform of the milling machine and is located below the milling cutter. The right part of the fixed base 10 extends out of the machining platform and is fixed to an externally mounted frame.

[0020] The top surface of the top plate of the fixed base 10 is fixed with transverse guide rails 11 at the front and rear. The clamping moving plate 20 is located above the two transverse guide rails 11. The bottom surface of the clamping moving plate 20 is fixed with multiple sliders 21 at the front and rear. The sliders 21 are inserted into the corresponding transverse guide rails 11.

[0021] The clamping moving plate 20 has a stationary vortex 100 to be processed placed in the middle of its top surface. Rotary clamping cylinders 22 are fixed on the top surfaces of the clamping moving plate 20 at the left, right, front and rear parts of the stationary vortex 100. The pressure block 222 fixed at the bottom surface of the end of the rotating pressing arm 221 of the rotary pressing cylinder 22 presses against the top surface of the corresponding side of the stationary vortex 100.

[0022] A lateral moving mechanism is fixed on the fixed base 10, which drives the clamping moving plate 20 to move left and right.

[0023] The top surface of the top plate of the fixed base 10 has a through groove 12 extending to the left and right. The lateral movement mechanism includes a fixed plate on the bottom surface of the top plate of the fixed base 10 fixed at both ends of the through groove 12. The two ends of the left and right extending moving screw 30 are movably connected to the two fixed plates through bearings. A moving servo motor 31 is fixed on one of the fixed plates. The output shaft of the moving servo motor 31 is a spline shaft, which is inserted into the spline hole at one end of the moving screw 30 and drives the moving screw 30 to rotate. The moving block 32 is screwed onto the moving screw 30. The upper part of the moving block 32 extends out of the through groove 12 and is fixed on the bottom surface of the middle part of the clamping moving plate 20.

[0024] The clamping moving plate 20 is fixed with an outer elastic sealing plate 1 on its front and rear side walls and left and right side walls. The bottom surface of the outer elastic sealing plate 1 is in close contact with the top surface of the top plate of the fixed base 10. The outer elastic sealing plate 1 has a sealing effect, reducing the probability of waste generated during processing entering the through groove 12.

[0025] The outer elastic sealing plates 1 on the left and right sides of the clamping moving plate 20 are formed with through holes, and the transverse guide rail 11 is inserted into the through holes. The inner sidewall of the through hole is close to or tightly attached to the inner sidewall of the transverse guide rail 11.

[0026] The clamping moving plate 20 covers the entire through slot 12.

[0027] Furthermore, the clamping moving plate 20 has four right-angle bent limiting blocks 2 fixed in the middle. The four corners of the bottom end of the stationary vortex disk 100 are inserted into the right-angle grooves of the corresponding limiting blocks 2. The side walls of the four corners of the bottom end of the stationary vortex disk 100 are tightly attached to the inner side walls of the corresponding right-angle grooves and cooperate with each other.

[0028] Connecting blocks are fixed on both the left and right ends of the through groove 12. Proximity sensors 3 and positioning blocks 4 are fixed on the connecting blocks. Wear-resistant anti-collision blocks 5 are fixed on the end faces of the positioning blocks 4. The left and right ends of the moving block 32 correspond to the sensing ends of the corresponding proximity sensors 3 and the wear-resistant anti-collision blocks 5.

[0029] A support block 26 is fixed on the top surface of the clamping movable plate 20 located below the middle of the upper part of the left and right sides of the static vortex disk 100. An adjustment screw hole is formed in the middle of the top surface of the support block 26. An adjustment stud 27 is screwed into the adjustment screw hole. The top of the adjustment stud 27 extends out of the top surface of the support block 26 and forms or fixes a horizontal support block 28. The top surface of the horizontal support block 28 is in close contact with the bottom middle of the left or right side extension of the static vortex disk 100.

[0030] A locking nut 29 is screwed onto the upper part of the adjusting stud 27, and the bottom surface of the locking nut 29 presses against the top surface of the support block 26. The locking nut 29 can be loosened, and the adjusting stud 27 can be rotated to change the top surface of the horizontal support block 28 so that its top surface is exactly the bottom surface of the middle part of the left or right extension of the stationary volute 100, thus ensuring that the stationary volute 100 is placed horizontally.

[0031] All electrical components in this embodiment are electrically connected to the control host via electrical connection lines, and are controlled by the control host. This is a conventional structure and will not be described in detail here.

[0032] In this embodiment, when in use, the four corners of the bottom end of the stationary volute 100 to be processed are inserted into the right-angled grooves of the corresponding limiting block 2. If the four corners of the bottom end of the stationary volute 100 cannot be inserted into the right-angled grooves of the corresponding limiting block 2, it indicates that its processing is not standard and it is directly rejected. Its bottom surface is pressed against the top surface of the clamping moving plate 20. Then, the four rotating clamping cylinders 22 operate, so that the pressure block 222 fixed at the bottom surface of the rotating clamping arm 221 of the rotating clamping cylinder 22 is pressed against the top surface of the corresponding side of the stationary volute 100 to achieve fixation.

[0033] This process is performed when the moving block 32 is at the right end. At this time, the stationary scroll plate 100 is installed outside the machining platform, which makes the operating space around it large and it is not under the milling cutter, making it easy to install and disassemble without damaging the milling cutter and ensuring the service life of the milling cutter.

[0034] Then, by moving the servo motor 31, the moving block 32 moves to the left until it is sensed by the proximity sensor 3 on the left and rests against the corresponding wear-resistant anti-collision block 5. At this time, the proximity sensor 3 sends the sensing signal to the control host, and the control host controls the servo motor 31 to stop running. This is the initial position for machining. Then, the milling cutter can move. After tool setting, it is set as the initial position of the milling cutter. Then, the groove milling is performed.

[0035] After machining is completed, the milling machine or machining center tool returns to its original position. The moving servo motor 31 runs, and the moving block 32 moves to the right until it is sensed by the right-side proximity sensor 3 and rests against the corresponding wear-resistant anti-collision block 5, indicating that it has returned to its original position. All rotating clamping cylinders 22 and rotating pressing arms 221 reset, and the machined stationary scroll plate 100 can be taken out. Then, the new stationary scroll plate 100 to be machined is installed, and the moving servo motor 31 runs again, moving to the left end. As before, the left-side proximity sensor 3 senses and rests against the corresponding wear-resistant anti-collision block 5. At this time, there is no need for tool setting. The milling cutter only needs to be moved to the previously set initial position to carry out subsequent machining. There is basically no need to adjust the tool position afterward, making machining convenient.

[0036] The above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model, and the patent protection scope of the present utility model should be defined by the claims.
