Description

Technical Field

[0001] This invention relates to the field of cylinder head manufacturing technology, and more specifically to a processing equipment for manufacturing cylinder heads for diaphragm compressors. Background Technology

[0002] The cylinder head of a diaphragm compressor is a crucial component, used to connect to the cylinder head and secure the sealing diaphragm. To ensure good sealing performance, a large number of bolts are needed to fix the cylinder head to the cylinder head; therefore, when machining the cylinder head, a significant number of bolt holes need to be drilled along its edges.

[0003] Because the borehole diameter in diaphragm compressor cylinder heads is relatively large, resulting in a significant amount of drilling chips, it is typically necessary to first pre-drill the hole using a smaller diameter drill bit, and then switch to a larger drill bit for the final drilling. Furthermore, after each pre-drilling operation, to ensure drilling accuracy, the debris inside and around the pre-drilled hole needs to be cleaned, an operation currently performed manually. Additionally, due to the large amount of drilling chips, drilling lubricant must be manually applied to the drill bit before each drilling operation to protect it. The entire processing requires multiple machine stops, resulting in low processing efficiency for diaphragm compressor cylinder heads. Therefore, a processing equipment for producing diaphragm compressor cylinder heads is needed to solve these problems. Summary of the Invention

[0004] The purpose of this invention is to provide a processing equipment for producing cylinder heads of diaphragm compressors, so as to solve the problems existing in the prior art mentioned in the background section.

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] Please see Figure 1-7 The present invention provides the following technical solutions:

[0035] A processing equipment for producing cylinder heads of diaphragm compressors includes: a frame 1, a worktable 2 mounted on the upper end of the frame 1, a through groove on the worktable 2, a vertical plate 5 mounted at the edge of the through groove, a lifting frame 6 vertically slidably connected to the vertical plate 5, and a lifting drive assembly 7 for driving the lifting frame 6 to slide on the vertical plate 5. The lifting frame 6 can pass through the through groove on the worktable 2 when sliding. The lifting drive assembly 7 is a linear slide, and the drive block of the linear slide is connected to the lifting frame 6. The linear slide can precisely control the lifting movement of the lifting frame 6.

[0036] A clamping assembly 3 is mounted on the workbench 2 and is used to clamp and position the cylinder head workpiece 11. The clamping assembly 3 includes a support plate 31, a connecting shaft 32, and a clamping block 33. The support plate 31 is rotatably connected to the workbench 2 via the connecting shaft 32. The support plate 31 is circular in the middle and has several elongated plates extending around it. The elongated plates are equidistantly distributed on the circular middle plate. The clamping block 33 is slidably connected to a groove on the elongated plate. The sliding of the clamping block 33 can achieve clamping and positioning of the cylinder head workpiece 11.

[0037] The lower end of the clamping block 33 is connected to a pull rod 34. A drive disk 36 is rotatably connected to the connecting shaft 32. The drive disk 36 has several arc-shaped grooves, the center of which is eccentrically set with respect to the axis of the connecting shaft 32. One end of the pull rod 34 is connected to a first drive column 35 that slides within the arc-shaped groove. The rotation of the drive disk 36 can drive the clamping block 33 to slide. The lower end face of the support plate 31 is connected to a first bracket 37. A cylinder 38 is mounted on the first bracket 37. The output end of the cylinder 38 is connected to a straight groove ring 39. A second drive column 310 is connected to the eccentric position of the drive disk 36. The second drive column 310 is slidably connected within the straight groove ring 39. The cylinder 38 is used to drive the drive disk 36 to rotate.

[0038] A rotary drive assembly 4 is mounted on the lower end face of the worktable 2. The rotary drive assembly 4 is used to drive the clamping assembly 3 to rotate. The rotary drive assembly 4 includes a driven gear 41 keyed to the connecting shaft 32, a second bracket 42, and a servo motor 43. The second bracket 42 is mounted on the lower end face of the worktable 2, and the servo motor 43 is mounted on the second bracket 42. The output end of the servo motor 43 is keyed to a driving gear 44 that meshes with the driven gear 41. The rotary drive assembly 4 drives the clamping assembly 3 to rotate, causing the cylinder head workpiece 11 on the clamping assembly 3 to rotate, thereby realizing the switching of the processing position of the cylinder head workpiece 11.

[0039] A drilling assembly 8 is installed on the upper and lower sides of the lifting frame 6 and is used to drill and enlarge holes in the cylinder head workpiece 11. The drilling assembly 8 includes a drilling motor 81 and a drill bit 82. The drilling motor 81 is installed on the upper and lower end faces of the lifting frame 6, and the two drilling motors 81 are staggered. The drill bit 82 is installed on the output end of the drilling motor 81. The upper side of the lifting frame 6 has a smaller diameter drill bit 82, and the lower side of the lifting frame 6 has a larger diameter drill bit 82.

[0040] A chip removal assembly 9 is installed on one side of the drilling assembly 8 and is used to clean the debris inside and around the adjacent openings when the drilling assembly 8 is drilling. The chip removal assembly 9 includes a connecting rod 91, a blower head 92, and a drive plate 93. The connecting rod 91 slides vertically in a through hole on the lifting frame 6. The blower head 92 is installed at the lower end of the connecting rod 91. A limit ring is connected to the upper end of the connecting rod 91. The drive plate 93 is connected to the blower head 92. An airbag 94 is provided between the drive plate 93 and the lifting frame 6. A return spring is provided inside the airbag 94. The airbag 94 and the blower head 92 are connected by a pipe.

[0041] The lower end of the blow nozzle 92 has a conical structure, and several spray holes are evenly distributed on the conical surface of the blow nozzle 92. When the conical blow nozzle 92 contacts the drill hole on the cylinder head workpiece 11, part of the conical structure of the blow nozzle 92 enters the drill hole, and part of it is outside the drill hole. The blow nozzle 92 inside the drill hole can clean the inner wall of the drill hole, while the spray holes on the blow nozzle 92 outside the drill hole are inclined towards the surface of the cylinder head workpiece 11, which can clean the debris around the drill hole. The debris cleaning component 9 can use the power of the lifting frame 6 to move up and down to provide a cleaning air source, and use the special structure of the blow nozzle 92 to clean the debris inside and around the drill hole.

[0042] An oiling assembly 10 is installed on the upper and lower end faces of the lifting frame 6. The oiling assembly 10 is used to apply oil to the drill bit 82 before drilling. The oiling assembly 10 includes a piston cylinder 101, a piston rod 102, and a piston 103. The piston cylinder 101 is installed on the upper and lower end faces of the lifting frame 6. The piston 103 is slidably connected inside the piston cylinder 101. The piston rod 102 is connected to the piston 103. One end of the piston rod 102 is connected to the corresponding drive plate 93.

[0043] The piston cylinder 101 has an oil inlet and an oil outlet on its end face, and each oil inlet and outlet is equipped with a corresponding one-way valve. The upper and lower sides of the lifting frame 6 are equipped with oil spray heads for applying oil to the corresponding drilling components 8. The oil outlet of the piston cylinder 101 on the upper side of the lifting frame 6 is connected to the oil spray head on the lower side of the lifting frame 6 through a pipe, and the oil outlet of the piston cylinder 101 on the lower side of the lifting frame 6 is connected to the oil spray head on the upper side of the lifting frame 6 through a pipe. The oil inlets of both piston cylinders 101 are connected to the oil tank 104 through pipes. When one drill bit 82 is drilling, the oiling component 10 can apply oil to the other drill bit 82 to ensure that the cylinder head workpiece 11 can be continuously drilled.

[0044] The working process of this invention is as follows:

[0045] When drilling is required on the cylinder head workpiece 11, the cylinder head workpiece 11 is first placed on the support plate 31. The cylinder 38 is started to drive the straight groove ring 39 to move. The straight groove ring 39 drives the drive plate 36 to rotate through the second drive column 310. The drive plate 36 drives the clamping block 33 to move closer to the center of the support plate 31 through the pull rod 34, thereby realizing the clamping and positioning operation of the cylinder head workpiece 11.

[0046] The drilling assembly 8 above the lifting frame 6 is activated, and the lifting drive assembly 7 drives the lifting frame 6 to move downward. The lifting frame 6 drives the drilling assembly 8 to move downward synchronously, so that the drilling assembly 8 can pre-drill holes in the cylinder head workpiece 11. During this process, when the blow nozzle 92 contacts the edge of the pre-drilled hole on the cylinder head workpiece 11 (the hole is adjacent to the hole being drilled), the lifting frame 6 continues to move downward, so that the blow nozzle 92 drives the drive plate 93 to squeeze the air bag 94. The air bag 94 supplies air into the blow nozzle 92 to blow away the debris inside and around the pre-drilled hole, preparing for the hole enlargement process.

[0047] During the movement of the drive plate 93 relative to the lifting frame 6, the drive plate 93 drives the piston rod 102 connected to it to move. The piston rod 102 drives the piston 103 to squeeze the lubricating oil in the piston cylinder 101, so that the lubricating oil is supplied to the oil spray head below the lifting frame 6 to achieve oiling of the reaming drill bit 82.

[0048] After the pre-drilling is completed, the lifting drive assembly 7 drives the lifting frame 6 to move upward, and the drilling assembly 8 below the lifting frame 6 starts to enlarge the pre-drilled hole after cleaning. During this process, the chip removal assembly 9 below the lifting frame 6 cleans the adjacent holes that have been enlarged, and the oiling assembly 10 below the lifting frame 6 supplies oil to the pre-drilled drill bit 82. After the enlargement is completed, the lifting frame 6 moves to the middle position, and the rotation drive assembly 4 drives the clamping assembly 3 to rotate, thereby switching the machining position of the cylinder head workpiece 11. By repeating the above steps, the drilling of the cylinder head workpiece 11 can be completed.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
