Description

Technical Field

[0002] When processing the cylinder head of the diaphragm compressor, it is necessary to process multiple equally spaced mounting holes on its edge for subsequent installation.

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] like Figures 1 to 7 As shown, a diaphragm compressor cylinder head processing device includes a radial drive mechanism 1, a clamping and positioning mechanism 2, and at least three tool head drive mechanisms 3 arranged at equal intervals in the circumferential direction around the clamping and positioning mechanism 2, and the tool head drive mechanism 3 is provided with an end mill 4 for grooving and drilling. The radial drive mechanism 1 is used to drive a plurality of tool head drive mechanisms 3 to move in the radial direction around the clamping and positioning mechanism 2, so as to adjust the position of the end mill 4 so that the end mill 4 can drill a hole at the edge of the cylinder head, and to move the end mill 4 along the radial direction of the cylinder head so that an air guide groove connected to the exhaust hole is formed on the cylinder head.

[0035] In addition, a multifunctional clamp 6 is provided on the tool head driving mechanism 3 through the lifting driving cylinder 5. The radial driving mechanism 1 drives several tool head driving mechanisms 3 to approach each other, so that several multifunctional clamps 6 clamp and position the cylinder head that can slide in any horizontal direction. After the clamping and positioning mechanism 2 clamps and positions the cylinder head, the lifting and driving cylinder 5 drives the multifunctional clamp 6 to rise above the cylinder head to avoid affecting the radial movement of the tool head driving mechanism 3 during grooving and hole opening. In addition, a coolant channel 19 for spraying coolant to the rear of the moving direction of the end mill 4 is tilted downward on the multifunctional clamp 6. Compared with the method of spraying coolant in a ring shape around the end mill 4, the method of spraying coolant from the rear of the end mill 4 to the air guide groove has a better driving effect on waste chips, and can enable the waste chips to fully move along the air guide groove to the exhaust hole in the center of the cylinder head for discharge.

[0036] The reason why the cylinder head is not clamped by driving the multifunctional jaws 6 to move radially is to ensure that the initial positions of the multiple end mills 4 relative to the cylinder head are the same after the cylinder head is positioned by multiple multifunctional jaws 6. If the multifunctional jaws 6 move and clamp the cylinder head in a radial motion, the initial position of the end mill 4 relative to the cylinder head will be affected by the positioning error of the multifunctional jaws 6, thereby affecting the processing accuracy of the air guide groove and the mounting hole.

[0037] Among them, the tool head driving mechanism 3 includes a sliding shell 301, a high-speed motor 302 and a tool holder 304. The high-speed motor 302 and the lifting drive cylinder 5 are both arranged on the top of the sliding shell 301. The tool holder 304 is rotatably arranged at the bottom of the sliding shell 301. The end mill 4 is arranged on the tool holder 304, and the tool holder 304 is located at the proximal end of the sliding shell 301 close to the center of the cylinder head, so that the groove formed by the end mill 4 can be connected to the exhaust hole in the center of the cylinder head, and it is avoided that several high-speed motors 302 hinder the end mill 4 from moving toward the center of the cylinder head when approaching each other. The high-speed motor 302 and the tool holder 304 are connected through a transmission assembly 303 arranged in the internal cavity of the sliding shell 301, so that the high-speed motor 302 can drive the tool holder 304 equipped with the end mill 4 to rotate through the transmission assembly 303.

[0038] The radial drive mechanism 1 includes a guide support frame 101 and a plurality of lead screws 102. The guide support frame 101 is provided with a plurality of guide grooves 7 of the same number as the tool head drive mechanism 3. The sliding shell 301 is slidably arranged in the guide groove 7. The lead screw 102 is arranged on the guide support frame 101 and is connected to the corresponding sliding shell 301. A center hole 8 for the clamping and positioning mechanism 2 to pass through is arranged in the center of the guide support frame 101.

[0039] Since the cutter head driving mechanism 3 will be subject to lateral resistance when the end mill 4 moves radially to perform grooving, in order to improve the stability and accuracy of the cutter head driving mechanism 3, a plurality of limit grooves 9 connected to the guide grooves 7 are arranged on the guide support frame 101, the width of the limit grooves 9 is greater than the width of the guide grooves 7, an anti-tilt shell 10 is slidably arranged in the limit grooves 9, the high-speed motor 302 slides with the limit grooves 9 with the aid of the anti-tilt shell 10, anti-tilt guide rails 11 are arranged on both side walls of the limit groove 9, and anti-tilt slide grooves 12 slideably cooperated with the anti-tilt guide rails 11 are arranged on both side walls of the anti-tilt shell 10, the stability of the high-speed motor 302 is protected by the cooperation between the anti-tilt guide rails 11 and the anti-tilt slide grooves 12, thereby maintaining the stability of the sliding shell 301 and the end mill 4, and preventing the high-speed motor 302 from shaking due to poor limiting when running at high speed.

[0040] In order to reduce the weight of the guide support frame 101 and reduce the vibration interference between multiple high-speed motors 302 and cause the guide support frame 101 to shake, the guide support frame 101 has a plurality of branches provided with guide grooves 7 and limit grooves 9, and a center hole 8 is provided at one end where the plurality of branches are connected to each other. The lead screw 102 is embedded in the side wall of the branch, and a side hole 13 is provided on the side wall of the branch for connecting the sliding shell 301 and the lead screw 102. The other ends of the plurality of branches that are away from each other are connected by a ring-shaped surrounding shell 14, thereby increasing the structural strength of the guide support frame 101.

[0041] In addition, a top cover 15 is provided on the top of the surrounding shell 14 to facilitate protection of the cutter head drive mechanism 3, and the clamping and positioning mechanism 2 includes a clamping cylinder 201, a guide column 202 and a positioning claw 203. The guide column 202 is slidably plugged into the center hole 8, and the clamping cylinder 201 is arranged on the top cover 15 and connected to the guide column 202. The side wall of the guide column 202 located below the guide support frame 101 is provided with a plurality of positioning claws 203 distributed at circumferential intervals. The guide column 202 clamps and positions the cylinder head with the aid of a plurality of positioning claws 203 extending laterally and downwardly at one end, that is, the guide column 202 is above the central exhaust hole of the cylinder head and clamps and fixes the cylinder head through a plurality of positioning claws 203. The positioning claws 203 are located between adjacent air guide grooves, and the purpose is to prevent the clamping and positioning mechanism 2 from hindering the end mill 4 from moving toward the exhaust hole of the cylinder head, so that the end mill 4 can machine an air guide groove connected to the exhaust hole. Furthermore, the guide column 202 is located above the exhaust hole, and the air guide groove is located between adjacent positioning claws 203, so that the coolant and flying chips in the air guide groove can smoothly move along the air guide groove to the exhaust hole in the center of the cylinder head.

[0042] The contact surface between the positioning claw 203 and the cylinder cover is provided with a rubber pad for preventing slipping and bumping.

[0043] In addition, the clamping cylinder 201 is rotatably arranged on the top cover 15 through the intermittent rotating mechanism 16 , and the intermittent rotating mechanism 16 drives the cylinder cover to rotate intermittently with the aid of the clamping positioning mechanism 2 , thereby facilitating reducing the number of the tool head driving mechanisms 3 .

[0044] In addition, it also includes a sliding surface processing platform 18 that supports the surrounding shell 14 through a plurality of lifting and adjusting cylinders 17, and a port for the cylinder head to pass through is formed between adjacent lifting and adjusting cylinders 17. The cylinder head is slidably set on the sliding surface processing platform 18 with a smooth and flat top directly or through a clamp slidably set on the sliding surface processing platform 18, so that the cylinder head can be driven to move by the multifunctional clamp 6, and driven to rotate by the rotating multiple positioning claws 203.

[0045] In addition, a waste liquid and waste chip discharge hole 20 is provided on the smooth surface processing platform 18. When the cylinder head is clamped and positioned by the multi-functional clamp 6, the exhaust hole in the center of the cylinder head is aligned with the waste liquid and waste chip discharge hole 20. The waste liquid and waste chip discharge hole 20 is used to discharge the coolant carrying iron chips discharged from the exhaust hole of the cylinder head.

[0046] The working principle of the present invention is as follows:

[0047] The cylinder cover is placed under the guide support frame 101, and then the lead screw 102 drives the sliding housing 301 to move outward, and the lifting drive cylinder 5 drives the multifunctional clamping claw 6 to fall. Subsequently, the lifting adjustment cylinder 17 drives the guide support frame 101 to descend, so that when the multiple lead screws 102 synchronously drive the multiple sliding housings 301 to move inward, the multiple multifunctional clamping claws 6 clamp the cylinder cover and align the exhaust hole of the cylinder cover with the guide column 202. Subsequently, the clamping cylinder 201 drives the guide column 202 to descend, so that the positioning claws 203 located around the exhaust hole press the cylinder cover into position. Subsequently, the lifting drive cylinder 5 drives the multifunctional clamping claw 6 to reset, and the lead screw 102 is pressed down. 02 drives the sliding housing 301 to move, so that the end mill 4 can move to above the opening position of the cylinder head edge. Then, with the descent of the lifting and adjusting cylinder 17 and the start-up of the high-speed motor 302, multiple end mills 4 synchronously open holes on the cylinder head. When grooving, the screw 102 drives the end mill 4 to move toward the exhaust hole, so that an air guide groove connected to the exhaust hole is formed on the travel path of the end mill 4. At the same time, the raised multifunctional clamp 6 pumps coolant to the coolant channel 19 through the coolant pumping device, and forms a coolant flow that sprays obliquely to the air guide groove behind the end mill, so as to drive the waste chips to be discharged from the center hole of the cylinder head along the air guide groove. Furthermore, according to the number of mounting holes and air guide grooves, if both are twice the number of end mills 4, after multiple end mills 4 complete a hole opening or groove opening, after the lifting and adjusting cylinder 17 lifts the guide support frame 101 until the end mill 4 is separated from the cylinder head, the intermittent rotation mechanism 16 drives the clamping cylinder 201 to rotate, so that the clamping cylinder 201 drives the cylinder head to rotate a corresponding angle with the help of the guide column 202 and the positioning grip 203, and then repeats the above-mentioned hole opening and groove opening steps until all mounting holes and guide grooves are processed.

[0048] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
