Abstract
Description
Technical Field
[0001] The invention belongs to the field of compressor parts processing devices, and in particular relates to a servo displacement metal inclined disc seat processing tool. Background Art
[0002] Swash plate compressors are widely used in indoor air conditioners, refrigerators, car air conditioners, cold storage, parallel refrigeration, commercial refrigeration and other fields due to their advantages of high efficiency, low noise and good stability.
[0003] like Figure 1-4 As shown, the inclined disc seat 9 is provided with an equal diameter oblique hole 91, which is formed by the oblique intersection of two equal diameter cylindrical holes A911 and cylindrical hole B912, the cylindrical hole B912 is a straight hole, the cylindrical hole A911 is an oblique hole, and the intersection angle between the cylindrical hole A911 and the cylindrical hole B912 is 20.66°. On the opposite end surface of the convex ring 92 of the inclined disc seat 9, a straight step hole 94 and an oblique step hole 95 are provided, the straight step hole 94 is concentric with the cylindrical hole B912, and the oblique step hole 95 is concentric with the cylindrical hole A911.
[0004] A certain part of the compressor main shaft is penetrated into the oblique hole 91, so that the swash plate seat 9 is fixed on the main shaft in the circumferential direction. The swash plate is provided with a threaded hole, and the outer part of the swash plate seat 9 is provided with a thread. The swash plate is sleeved on the outer part of the swash plate seat and is threadedly connected and fixed with the swash plate seat 9. The outer circumference of the compressor main shaft is also provided with a plurality of cylinders arranged in a circle, and each cylinder is provided with a bidirectional piston, one in front and one behind. The edge of the swash plate is embedded in the groove of the piston. When the main shaft rotates, the swash plate also rotates, and is driven by the swing arm to swing back and forth, so that the swash plate pushes the piston to perform axial reciprocating motion. After the swash plate rotates one circle, the front and rear pistons complete the suction, compression, exhaust, and expansion processes, which is equivalent to the action of two cylinders. Usually, when the compressor is at low speed or high load, the swash plate is at the maximum angle state, that is, when the piston runs to the maximum stroke. Conversely, when the compressor is at high speed or low speed load, the swash plate is at the minimum angle state, that is, when the piston runs to the minimum stroke.
[0005] Due to the above-mentioned special structure of the inclined disc seat 9, the current method for processing it is: first, the inclined disc seat 9 is axially and vertically clamped on the first set of fixtures of the milling machine, and then the basic hole on the inclined disc seat is expanded with a vertical milling cutter to process the cylindrical hole B912 and the straight step hole 94, and then the inclined disc seat 9 with the cylindrical hole B912 and the straight step hole 94 is removed from the first set of fixtures, and it is clamped on the second set of fixtures of the milling machine to process the cylindrical hole A911 and the inclined step hole 95. Since this processing method requires the use of two sets of fixtures and the inclined disc seat 9 needs to be manually clamped twice, it is easy to cause the processed cylindrical hole B912, the straight step hole 94, the cylindrical hole A911, and the inclined step hole 95 to have large error accumulation, which is very unfavorable for the high-precision processing of the finished product of the inclined disc seat 9, and it is easy to produce unqualified products. In addition, the second set of fixtures can only be used to clamp products that need to process cylindrical holes of specific angles, and the utilization rate after manufacturing is low, which makes the cost of this processing method also high. Summary of the invention
[0006] Therefore, the technical problem to be solved by the present invention is that the swash plate seat on the existing swash plate compressor needs to be processed by two sets of clamps and the swash plate seat needs to be manually clamped twice, which easily leads to large error accumulation, is not conducive to high-precision processing of the product, and easily produces unqualified products. In addition, the inclination angle of the second clamp is fixed and can only be used to process cylindrical holes of specific angles.

[0035] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0036] The present invention provides a servo displacement metal swash plate seat processing tool, including a lathe spindle 1, a spindle seat 2, a connecting frame 3, a pushing mechanism 4, a driving mechanism 5, a pull rod 6, a connecting rod 7 and a clamping portion 8. The lathe spindle 1 is connected to the spindle seat 2 for rotation around the Z axis. The pushing mechanism 4 and the driving mechanism 5 are fixedly installed on the connecting frame 3. The driving mechanism 5 drives the actuator of the pushing mechanism 4 to push and pull. The connecting frame 3 is fixed to the spindle seat 2. The lathe spindle 1 is a tubular structure. The main body 161 of the pull rod 6 is located inside the lathe spindle 1. , and is concentric with the lathe spindle 1, the rear end of the pull rod 6 extends out of the lathe spindle 1, the actuator of the pushing mechanism 4 is connected to the rear end of the pull rod 6 for rotation around the Z axis, the actuator of the pushing mechanism 4 can push and pull the pull rod 6 along the Z axis direction, the length direction of the pull rod 6 is consistent with the Z axis direction, the pull rod 6 is connected to the lathe spindle 1 for rotation around the Z axis, the clamping part 8 is connected to the front end of the lathe spindle 1 and swings around the X axis, the clamping part 8 is used to clamp the swash plate seat 9, and the two ends of the connecting rod 7 are respectively hinged to the front end of the pull rod 6 and the clamping part 8.
[0037] The pull rod 6 can be pushed and pulled forward and backward to adjust the angle of the connecting rod 7, thereby adjusting the angle of the clamping part 8, and then adjusting the angle of the swash plate seat 9 clamped on the clamping part 8, so that the swash plate seat 9 is tilted relative to the processing tool, so that the cylindrical hole A911 and the inclined step hole 95 can be processed. During processing, the tool does not rotate, and the lathe spindle 1 and the pull rod 6 rotate synchronously, thereby driving the clamping part 8 to rotate, and then driving the swash plate seat 9 to rotate. The actuator of the pushing mechanism 4 is connected to the rear end of the pull rod 6 around the Z axis, so that the actuator can drive the pull rod 6 to move forward and backward when it is pushed and pulled forward and backward, and when the pull rod 6 and the lathe spindle 1 rotate, it will not be interfered by the actuator of the pushing mechanism 4.
[0038] The main function of the present invention is to facilitate the processing of the oblique holes 91 (cylindrical holes A911 and cylindrical holes B912), the straight step holes 94 and the oblique step holes 95 in the inclined plate seat 9. The specific processing steps and methods are as follows:
[0039] In the first step, in the initial state, the front end of the pull rod 6 is relatively backward, the clamping part 8 is aligned, and the axial direction of the swash plate seat 9 is horizontal when it is clamped on the clamping part 8, that is, the axial direction of the base hole is horizontal;
[0040] In the second step, since the large end surface of the swash plate seat 9 already has a basic hole, the driving mechanism 5 of the lathe spindle 1 is started, the lathe spindle 1 rotates, and the turning tool with a horizontal axis is inserted into the basic hole to process the straight step hole 94 and the cylindrical hole B912 in sequence. Since the turning tool can move along the X-axis, the same turning tool can process straight step holes 94 and cylindrical holes B912 of different diameters.
[0041] The third step is to move the pull rod 6 forward so that the connecting rod 7 rotates 20.66° clockwise with the end hinged to the clamping part 8 as the rotation center, so that the clamping part 8 rotates 20.66° clockwise, and then the inclined plate seat 9 rotates 20.66° counterclockwise. First, use a rough boring tool to process the inclined step hole 95 and the cylindrical hole B912 in sequence. Since the rough boring tool can move along the X-axis, the same rough boring tool can process inclined step holes 95 and cylindrical holes B912 of different diameters. Then use a fine boring tool for fine processing. Since the fine boring tool can move along the X-axis, the same fine boring tool can perform fine processing on inclined step holes 95 and cylindrical holes B912 of different diameters.
[0042] In this process, the boring tool is inserted into the straight step hole 94 and the cylindrical hole B912 obtained in the second step and remains stationary, while the lathe spindle 1 rotates, driving the inclined plate seat 9 to rotate, and the cylindrical hole A911 and the inclined step hole 95 are processed;
[0043] The specific method of rotatably mounting the lathe spindle 1 on the spindle seat 2 is as follows: a mounting hole 21 is provided on the spindle seat 2, and the lathe spindle is inserted into the mounting hole 21. A first limiting ring 10 and a second limiting ring 11 having a diameter larger than the diameter of the mounting hole 21 are respectively provided at both ends of the lathe spindle 1. The first limiting ring 10 and the second limiting ring 11 are respectively attached to the rear side wall and the front side wall of the spindle seat 2, and the first limiting ring 10 is detachably fixed to the lathe spindle 1. When installing the lathe spindle 1, the first limiting ring 10 is removed from the lathe spindle 1 in advance, and after the lathe spindle 1 is inserted into the mounting hole 21, the first limiting ring 10 is installed on the lathe spindle 1. In this way, the rotation of the lathe spindle 1 on the spindle seat 2 can be realized, and the lathe spindle 1 cannot move in the Z-axis direction.
[0044] Specifically, the pushing mechanism 4 includes a screw 41, a rotating sleeve 42, a ball nut 43, a bearing seat 44 and a first bearing 45. The ball nut 43 is sleeved outside the screw 41, the first bearing 45 is fixedly installed in the bearing seat 44, the rotating sleeve 42 is sleeved outside the ball nut 43, and the rotating sleeve 42 is fixed to the ball nut 43. The rotating sleeve 42 is located in the inner ring of the first bearing 45 and is tightly matched with the inner ring of the first bearing 45. Since the rotating sleeve 42 is tightly matched with the first bearing 45, and the rotating sleeve 42 is fixed to the ball nut 43, the ball nut 43 is fixed to the inner ring of the first bearing 45. When the ball nut 43 is driven to rotate, the screw 41 will move axially relative to the ball nut 43 (bearing seat 44). When the ball nut 43 rotates forward, the screw 41 will move forward; when the ball nut 43 rotates reversely, the screw 41 will move backward. In the present invention, the screw rod 41 is the actuator of the pushing mechanism 4, which can push and pull the pull rod 6 in the Z-axis direction.
[0045] The driving mechanism 5 includes a driving motor 51, a first synchronous wheel 52, a second synchronous wheel 53 and a synchronous belt 54. The first synchronous wheel 52 is tightly sleeved outside the rotating sleeve 42, the second synchronous wheel 53 is fixed to the output end of the driving motor 51, and the first synchronous wheel 52 and the second synchronous wheel 53 are simultaneously surrounded by the synchronous belt 54. Due to the arrangement of the driving motor 51, the synchronous belt 54, the first synchronous wheel 52 and the second synchronous wheel 53, when the driving motor 51 is started, the rotating sleeve 42 can rotate, and the rotation of the rotating sleeve 42 can drive the ball nut 43 to rotate, thereby moving the screw rod 41.
[0046] The specific implementation method of the actuator of the pushing mechanism 4 and the rear end of the pull rod 6 rotating around the Z axis is as follows: a sleeve 12 is fixed to the rear end of the pull rod 6, a second bearing 13 is fixed inside the sleeve 12, and the front end of the screw rod 41 penetrates into the inner ring of the second bearing 13 and fits tightly with the second bearing 13.
[0047] A flange sleeve 14 is detachably fixed at the front end of the lathe spindle 1, and a third bearing 15 is fixed inside the flange sleeve 14. The front end of the pull rod 6 penetrates into the third bearing 15 and is loosely matched with the third bearing 15. The third bearing 15 provides support for the pull rod 6 to be concentrically arranged in the lathe spindle 1. Since the pull rod 6 and the third bearing 15 are loosely matched, the movement of the pull rod 6 in the second bearing 13 (i.e., in the lathe spindle 1) is not affected.
[0048] A chuck 16 is detachably fixed at the front end of the flange sleeve 14 . The chuck 16 includes a cylindrical main body 161 and two connecting claws 162 . The two connecting claws 162 are fixed at the front end of the main body 161 and extend along the Z-axis direction. The clamping portion 8 is hingedly installed between the two connecting claws 162 .
[0049] Specifically, the connecting frame 3 includes a first cross bar 31, a second cross bar 32, a first vertical plate 33, a second vertical plate 34 and a bottom plate 35. The length direction of the first cross bar 31 and the second cross bar 32 extends along the Z-axis direction, and the length direction of the first vertical plate 33 and the second vertical plate 34 extends along the Y-axis direction. The first vertical plate 33 and the second vertical plate 34 are respectively fixed to the two sides of the rear side wall of the spindle seat 2. One end of the first cross bar 31 is fixed to the bottom end of the first vertical plate 33, and one end of the second cross bar 32 is fixed to the bottom end of the second vertical plate 34. The bottom plate 35 is fixed to the first cross bar 31 and the second cross bar 32 at the same time, and the pushing mechanism 4 and the driving mechanism 5 are fixed to the bottom plate 35. The first vertical plate 33 and the second vertical plate 34 mainly play the role of fixing the connecting frame 3 to the spindle seat 2. The first cross bar 31 and the second cross bar 32 provide support for the bottom plate 35, and the bottom plate 35 provides support for the pushing mechanism 4 and the driving mechanism 5.
[0050] The clamping portion 8 includes a displacement block 81 and a clamping block 82 which are independent of each other. The displacement block 81 includes a square block 811, two opposite front connecting ears 812 and two opposite lower connecting ears 813. The two front connecting ears 812 are arranged on the front side of the square block 811, and the length direction of the front connecting ears 812 extends along the Z-axis direction. Each front connecting ear 812 is hinged to the connecting claw 162. The two lower connecting ears 813 are arranged on the lower side of the square block 811, and the length direction of the lower connecting ears 813 extends along the Y-axis direction. One end of the connecting rod 7 is hingedly installed between the two lower connecting ears 813; the clamping block 82 is fitted and fixed on the front side of the displacement block 81, and two mounting ears 821 are provided at the lower front side of the clamping block 82, and the length direction of the mounting ears 821 extends along the Z-axis direction. The pin sleeve of the inclined plate seat 9 is hingedly installed between the two mounting ears 821, and a through hole 822 is provided in the middle part of the clamping block 82, which is axially consistent with the Z-axis direction, and the convex ring 92 of the inclined plate seat 9 is inserted into the through hole 822.
[0051] The clamping block 82 is made of elastic material, and is provided with a notch 823 communicating with the through hole 822. Locking holes 824 are provided on both sides of the notch 823. Bolts can be inserted into the two locking holes 824, and nuts can be threaded on the bolts to adjust the size of the notch 823. After the convex ring 92 is placed in the through hole 822, the nut is tightened as close to the bolt head as possible to minimize the notch 823, so that the convex ring 92 is clamped in the through hole 822.
[0052] In the initial state, the front end of the tie rod 6 is in a suitable position, so that the slant disc seat 9 is axially horizontal, which is convenient for processing the cylindrical hole B912 and the straight step hole 94. After the cylindrical hole B912 and the straight step hole 94 are processed, the tie rod 6 will move a distance to the rear side to adjust the slant disc seat 9 to an inclined state, and process the inclined step hole 95 and the cylindrical hole A911. After the inclined step hole 95 and the cylindrical hole B912 are processed, the tie rod 6 is reset to the initial position to prepare for clamping the next slant disc seat 9 for processing. Therefore, the slant disc seat 9 in the present invention can be processed in sequence with only one clamping, the straight step hole 93, the cylindrical hole B912, the inclined step hole 95, and the cylindrical hole A911. In the present invention, the movement timing, movement distance and movement direction of the tie rod 6 are actually driven by the drive motor 51, and the drive of the drive motor 51 is controlled by a set software program.
[0053] The inclined disc seat 9 processed by the present invention has a diameter of 15.035±0.05mm for the cylindrical hole A911 and the cylindrical hole B912. The radius of the straight step hole 94 and the inclined step hole 95 are both 10.5±0.25mm. The line connecting the intersection of the cylindrical hole B912 and the cylindrical hole A911 is the line segment EF, and the intersection of the line segment EF and the center axis of the cylindrical hole B912 is the point g. The distance between the point g and the large end face is 2.685mm. The spacing between the convex ring end face and the large end face is 9.4mm. The spacing between the inclined step hole 95 and the point g is 6.7mm.
[0054] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
