Description

Assembly equipment for cam and clamp spring in automobile gearbox

Technical Field

Background

As shown in FIG. 1, the clamp spring 1 is provided with a clamp spring inner hole 1-1. As shown in fig. 2, the cam 2 is provided with a cam inner hole 2-2 provided with an edge angle 2-1 at its extended end. As shown in fig. 3, a shaft plate 65 is fixed at the lower end of the sleeve shaft 52, and the diameter of the shaft plate 65 is larger than that of the sleeve shaft 52, so as to form a platform abutting against the clamp spring 1. One end of the axle plate 65 is bent upward to form the flap 55.

As shown in fig. 3, the assembled part structure is: the torsion spring 4 is sleeved on the sleeve shaft 52, the bottom of the torsion spring 4 is arranged on the shaft plate 65, and the lowest extension end of the torsion spring 4 is abutted with the side face of the folded plate 55, so that when the sleeve shaft 52 rotates, the folded plate 55 pushes the torsion spring 4 to rotate together. The upper end of the torsion spring 4 is provided with a torsion spring supporting leg 3. A clip spring 1 is respectively arranged on the upper side and the lower side of the cam 2 at the upper end position of the sleeve shaft 52 on the torsion spring 4, namely, the respective inner holes are assembled with the sleeve shaft 52. The lower end face of the edge angle 2-1 of the cam 2 is convexly provided with a socket 2-3, and the socket 2-3 is inserted into the torsion spring leg 3 of the torsion spring 4.

The assembly of the cam 2 is generally completed manually at present, the efficiency is low, and the cam and other parts often have strict relative position requirements, so that high requirements on the precision of the automatic assembly of the cam are provided, and great difficulty is brought.

The same manual assembly adopted during the assembly of the clamp spring 1 often needs the steps of clamping, compressing (expanding), assembling and the like of the clamp spring by means of clamp spring pliers, and an operator is required to pay special attention to the clamping position during clamping so as to avoid clamping failure. When the spring is compressed (opened), additional force is needed, the spring is easy to bounce and separate from the spring pincers to hurt people, so that the requirement on the skill of operators is high, the physical consumption is high for a long time, and fatigue is easy to generate. The manual assembly is easy to cause excessive opening of the clamp spring (the problem of manual operation exists, and errors such as the shape, the position and the size of small holes and large holes of the clamp spring are easy to cause excessive clamping of the clamp spring during manual assembly, so that the clamp spring is oversized and is separated from a clamp spring groove, the function is invalid, and serious safety risks are easy to cause.

At present, automatic operation is also carried out on the assembly of the snap springs, but the following problems exist:

1. The common conical surface guiding type clamping spring press-fitting mode can scrape the surface of the shaft during press-fitting, and only one clamping spring can be assembled at a time from the same direction;

2. the clamping springs are easy to clamp in the assembly process, and the end surfaces of the clamping springs are required to be kept horizontal in the assembly process, otherwise, the clamping springs cannot completely enter the clamping spring grooves, and once the clamping springs incline, the clamping springs are clamped on the shaft or in the holes or jump off in the transfer process of the clamping springs;

3. When the clamp spring is used for assembling the shaft, two small holes of the clamp spring are adopted for grabbing, so that the inner hole 1-1 of the clamp spring is opened, and the opening size of the inner hole 1-1 of the clamp spring is limited by errors such as the shape, the position and the size of the small hole on the clamp spring and the inner hole of the clamp spring, so that the opening size of the inner hole of the clamp spring is inconsistent every time, the opening of the assembled clamp spring is excessive or too small, and the clamp spring is invalid or a mechanism is blocked. Meanwhile, the problem of consistency of the positions of the small holes is solved, automatic grabbing is achieved through positioning and assembling of the small holes, the assembling position is difficult to guarantee, and the two small hole clamping is extremely easy to cause unstable postures, and clamping stagnation is caused, so that assembling is failed.

Detailed Description

The invention will be described in detail below with reference to the drawings in connection with embodiments. It should be noted that, without conflict, the embodiments of the present invention and features of the embodiments may be combined with each other. For convenience of description, the words "upper", "lower", "left" and "right" are used hereinafter to denote only the directions corresponding to the upper, lower, left, and right directions of the drawings, and do not limit the structure.

As shown in fig. 4, the assembly device for the cam and the clamp spring in the automobile gearbox provided by the embodiment comprises a frame 51, a torsion spring limiting mechanism 9 arranged on the frame 51, a cam discharging mechanism 12 arranged at one side of the torsion spring limiting mechanism 9, a cam grabbing mechanism 10 arranged between the torsion spring limiting mechanism 9 and the cam discharging mechanism 12 in a moving manner, a clamp spring separating mechanism 8 and a clamp spring distributing mechanism 11 arranged at the other opposite side of the torsion spring limiting mechanism 9, and a clamp spring grabbing mechanism 13 arranged between the clamp spring separating mechanism 8 and the clamp spring distributing mechanism 11 in a moving manner.

The frame 51 has a horizontal table 51-1 and a vertical mounting table 51-2, and a forward/backward movement mechanism 7 is provided on the horizontal table 51-1, and the forward/backward movement mechanism 7 slides in the X direction.

A vertical movement mechanism 6 is stacked on the horizontal movement mechanism 5, and the vertical movement mechanism 6 slides in the Z direction.

As shown in fig. 3 and 4, the torsion spring limiting mechanism 9 is disposed on the horizontal table 51-1 and is disposed near the vertical mounting table 51-2. As shown in fig. 5, the torsion spring limiting mechanism 9 is an assembly station, and the clamp spring, the cam and the torsion spring are all installed at the assembly station, so that the assembly shown in fig. 3 is finally formed.

As shown in fig. 6, the torsion spring limiting mechanism 9 includes a pressing block 14, a baffle 15, a gear motor 16 and a gear pair 17.

The gear motor 16 and the pressing block 14 are arranged side by side on the frame 51, and a gear pair 17 and a horizontal workbench 51-1 are arranged between the gear motor and the pressing block to rotate. The pressing block 14 is provided with a clamping groove 53 capable of clamping the sleeve shaft 52, and the clamping groove 53 can be clamped on the side wall of the sleeve shaft 52 in a butt clamping mode. When the pressing block 14 is driven to rotate by the gear motor 16, the sleeve shaft 52 fixed together with the pressing block 14 by clamping rotates together. At this time, the folded plate 55 drives the torsion spring 4 to rotate together until the torsion spring leg 3 contacts with the baffle 15, and the rotation is stopped, and the state to be assembled is entered.

As shown in fig. 5, a cam discharging mechanism 12 is provided at a side of the torsion spring stopper mechanism 9, the side being offset to the right in the Y direction. As shown in fig. 7, the cam discharging mechanism 12 includes a mounting plate 12-1, a limiting shaft 12-2 and a flange 12-3. The mounting plate 12-1 is mounted on the frame 51, one side of the mounting plate is provided with a chord edge, and the center of the chord edge is provided with the limiting shaft 12-2. The flange 12-3 is arranged at the center of the mounting plate 12-1, and the flange 12-3 is hollow. As shown in fig. 7, the end side of the edge angle 2-1 of the cam 2 is provided with a protruding socket 2-3, and as shown in fig. 3, the socket 2-3 is used for inserting a torsion spring leg 3 of a torsion spring 4 at the upper end.

When the cam 2 is placed, the socket 2-3 is aligned with the limiting shaft 12-2, so that other parts of the cam 2 are placed in the space surrounded by the flanges 12-3.

As shown in fig. 5, a cam grabbing mechanism 10 is disposed above the cam discharging mechanism 12, and the cam grabbing mechanism 10 is suspended above the cam discharging mechanism 12 by a column mounted on a frame 51 and a plate chain disposed on the column, and is positioned between the cam discharging mechanism 12 and a torsion spring limiting mechanism 9.

As shown in fig. 8-10, the cam grabbing mechanism 10 includes a cantilever plate 56 mounted above the frame 51, and a position correcting assembly, a grabbing assembly and a pushing assembly suspended on the cantilever plate 56, where the correcting assembly is located at the side of the grabbing assembly, and the pushing assembly is located in the grabbing assembly and stretches downward.

The correction assembly comprises a supporting rod 59, a finger rod 20, a connecting plate 60 and two sixth air cylinders 50 arranged on the cantilever plate 56, wherein a supporting lug 57 is arranged on one side of a telescopic rod of each sixth air cylinder 50, a supporting shaft 58 is arranged at the bottom of each supporting lug 57, one end of the supporting rod 59 is inserted into each supporting lug 57, and the upper end face of the inserted end of the supporting rod 59 is connected with the inner top face of each supporting lug 57 through a spring 21. At the same time, the telescopic rod of the sixth cylinder 50 is inserted into the spring 21, and when necessary, the telescopic rod is extended to be in contact with the strut 59, and when not necessary, the telescopic rod is retracted, and the telescopic rod and the strut are not in contact. The other end of the supporting rod 59 is hinged with the finger rod 20, and the tail end of the finger rod 20 is hinged with a roller. The connection plate 60 connects the two hinged fingers 20, and a mounting plate 61 is hinged at the middle of the connection plate 60, and the mounting plate 61 is connected with the cantilever plate 56.

When the cam grabbing mechanism 10 contacts the cam 2, the edge angle 2-1 of the cam 2 firstly enters between the two finger rods 20 and presses the supporting rod 59, the supporting rod 59 pushes the cam 2 to the symmetrical axis position of the two finger rods 20 under the action of elastic force, and after the elastic forces on the two sides are balanced, the cam stops moving.

When the sixth cylinder 50 is operated, the telescopic rod thereof extends to abut against one end of the supporting rod 59 extending into the supporting lug 57 to move downwards, and the other end of the supporting rod 59 moves upwards, thereby driving the finger 20 to rotate inwards (the direction in which the two fingers approach each other); otherwise, the device rotates outwards; the position of the cam 2 is thus readjusted repeatedly so that it nests on the torsion spring leg 3.

When the socket 2-3 on the cam 2 and the torsion spring supporting leg 3 are slightly different and the assembly is unsuccessful, the finger rod 20 can be driven to be opened and closed continuously through the staggered up-and-down actions of the sixth air cylinders 50 on the two sides, and the intermittent extrusion action is implemented on the cam 2. Meanwhile, the sixth cylinder 50 is not directly connected with the finger 20, but applies acting force through the spring 21, so that a buffering effect is achieved, slight vibration is formed, the cam 2 and the torsion spring supporting leg 3 can be successfully assembled in the buffered slight vibration, and an abnormal condition correcting effect is achieved to a certain extent.

As shown in fig. 9, the grabbing assembly comprises a three-finger clamping jaw 19, and the three-finger clamping jaw is installed on an air jaw of an air cylinder and driven by the air jaw, which is the prior art. The three-finger clamping jaw 19 is simultaneously opened under the action of the air cylinder, and the cam inner hole 2-2 is expanded, so that the self-centering grabbing effect is achieved.

The jacking assembly includes a cylinder (not numbered) and a compression bar 18 drivingly connected to the cylinder. The cylinder is mounted on the cantilever plate 56, and the compression bar 18 is positioned in the middle of the three-finger clamping jaw 19 and stretches downwards.

During grabbing, the finger rod 20 is contacted with the edge angle 2-1 of the cam 2 to be positioned at first, then the finger rod 18 is abutted against the end face of the cam 2, and then the three-finger clamping jaw 19 is propped against the inner hole 2-2 of the cam in an internal mode, so that stable grabbing is achieved.

The specific working principle is as follows: the cam grabbing mechanism 10 descends, and the edge angle 2-1 of the cam 2 enters between the two fingers 20, so that the fingers 20 can synchronously act to correct the position of the cam 2, and the cam 2 moves to the symmetrical axis position of the two fingers 20. The plunger 18 is actuated to contact the cam 2 and compress it. And the three-finger clamping jaw 19 is opened, the cam 2 is expanded from the cam inner hole 2-2, the grabbing effect is achieved, and the cam grabbing mechanism 10 drives the cam 2 to ascend. After waiting for the first clamping spring 1 to be installed, the cam 2 is assembled again.

As shown in fig. 4 and 5, the jump ring feed mechanism 11 is located at the end of the horizontal table 51-1 far from the vertical mounting table 51-2, and is located at the middle position in the Y direction.

The side of the positioning support 24 away from the push plate 25 is provided with a vertically through blanking port (not shown), and the blanking port is located at the vertically extending end of the cartridge clip type bin 27. A push rod 28 is arranged at the top of the blanking port in a telescopic mode, and the push rod 28 is driven by the first air cylinder 22. And the chute 49 is horizontally communicated with the blanking port. The push plate 25 is driven by a second cylinder 26 mounted on a base 62. The first cylinder 22 is arranged on a guide seat 23.

As shown in fig. 4 and 11, the cartridge bin 27 is connected with a vibration plate, and is automatically fed through the vibration plate. The clip type bin 27 is stacked, the clip spring 1 placed at the lowest position is placed in the sliding groove 49, the height of the sliding groove 49 is only used for the space of one clip spring 1, and when the clip spring 1 is pushed out by the push plate 25, one clip spring falls down automatically according to self weight.

The push plate 25 is telescopically formed with a first position, in which the push plate 25 is disposed away from the positioning support 24, a second position and a third position. In the second position, the push plate 25 extends into the positioning seat 24 and the chute 49 and is positioned adjacent to the cartridge magazine 27 (i.e. in contact with the circlip 1 that falls into the chute 49). In the third position, the push plate 25 continues to extend into the vicinity of the blanking port (i.e., the clip spring 1 is pushed into the blanking port). Then the first cylinder 22 pushes the ejector rod 28 to act, so that the clamp spring 1 is pushed out from the blanking port to fall. The cross-section of push pedal 25 is T shape, is the installation of reverse T shape during the installation, has the horizontal limit that can sliding fit promptly to and can promote the vertical limit of jump ring displacement, the precision is better, and sliding displacement stability is better.
