Detailed Description

The following specific examples are intended to be illustrative of the utility model and are not intended to be limiting, as modifications of the utility model will be apparent to those skilled in the art upon reading the specification without inventive contribution thereto, and are intended to be protected by the patent law within the scope of the appended claims.

The scheme is realized by the following technical means:

example 1: in the embodiment, an automatic preassembling device for the components of the spring pressing-in roller body A, which is configured in advance in a combined manner before the main body components of the roller body A, the rotary supporting shaft B and the reset spring C are completely pressed and fixed in the process of producing the spring pressing-in roller is provided.

In the device provided in this embodiment, the device mainly comprises four parts, namely a roller body moving and conveying mechanism 1, a rotating support shaft assembling and conveying mechanism 2, a return spring feeding and conveying mechanism 3 and a return spring-rotating support shaft sleeving and pressing auxiliary mechanism 4.

First, the apparatus comprises a unitary support platform on the upper surface of which the mechanisms are mounted. The roller body moving and conveying mechanism 1 comprises two first conveying belts 101 which are symmetrically arranged at two sides, wherein the first conveying belts 101 can be in a chain form formed by mutually connecting a plurality of chain links, and meanwhile, the two first conveying belts 101 extend along the front-back direction of the bearing platform; the chain links of the first conveyor belts 101 are fixedly provided with a plurality of bearing blocks 102 at equal intervals, and the bearing blocks 102 on the two first conveyor chains are symmetrical to each other. The supporting block 102 is made of plastic or rubber, the bottom of the supporting block is fixedly connected with the first conveying belt 101, and the top surface of the supporting block is provided with a V-shaped notch which is concave downwards.

When the cylindrical pipe-shaped roller body a is placed on the two opposite supporting blocks 102 from top to bottom, the pair of supporting blocks 102 can play a stable supporting role at the two end positions of the roller body a. When the two first conveyor belts 101 simultaneously encircle the driving wheels at both sides and continuously move forward under the drive of the driving device, the supporting blocks 102 on the first conveyor belts 101 also move forward along with the chain links, so that the roller bodies A erected on the two opposite supporting blocks 102 are driven to move forward.

Along the extending direction of the first conveyor belt 101, a rotary support shaft assembly conveyor 2 is provided on the side of the front section of the roller body movement conveyor 1. Specifically, the rotary supporting shaft assembly conveying mechanism 2 includes a second conveying belt 201 that is also horizontally disposed, and the second conveying belt 201 is located outside the two first conveying belts 101 and is perpendicular to the extending direction of the first conveying belts 101. The second conveyor belt 201 can also move continuously in one direction under the drive of another independent driving device. When the rotation support shaft B in the form of an elongated rod is placed on the second conveyor belt 201, the rotation support shaft B can also be pushed forward and inserted into the hollow tubular roller body a with the movement of the second conveyor belt 201. Then, the first conveyor belts 101 at both sides drive the roller body a with the rotary support shaft B inserted to move to the next station.

Here, the movement of the first conveyor belt 101 is not continuous, but is an intermittent movement pattern, unlike the intermittent movement of the second conveyor belt 201, and a limit stopper 7 is further installed at the end position of the second conveyor belt 201. When the first conveyor belt 101 moves the supporting block 102 mounted thereon and the roller body a carried thereon to a position facing the end of the second conveyor belt 201, the driving means of the first conveyor belt 101 is stopped, so that the roller body a stays at the position for a short time. At this time, the blocking portion in the limit blocking device 7 is lifted upward to release the restriction effect on the swing support shaft, which moves forward under the pushing action of the second conveyor belt 201, is inserted into the roller body a and leaves the second conveyor belt 201. After this process is completed, the first conveyor belt 101 will move again and drive the combined roller body a and the rotating support shaft to move together to the next station, and the blocking portion will also fall again to block and limit the next rotating support shaft.

Referring to the drawings given in this embodiment, along the extending direction of the first conveyor belt 101, the return spring loading conveyor 3 and the return spring-rotating support shaft sleeve press-fit auxiliary mechanism 4 are both disposed on the rear side of the foregoing rotating support shaft assembly conveyor 2. Specifically, the return spring loading conveyor 3 includes a third conveyor 301 similar to the second conveyor 201 described above. When the return spring C is placed on the third conveyor belt 301 in a horizontal square state, the third conveyor belt 301 is driven by an independent driving device to move from front to back, and the return spring C above the third conveyor belt 301 is continuously pushed forward. The third conveyor belt 301 also adopts a continuous operation mode, so that a blocking member is fixedly arranged at the front part of the third conveyor belt 301 to avoid falling off from the third conveyor belt 301 under the action of the reset spring C.

At the opposite position to the end of the third conveyor belt 301, a return spring-rotation supporting shaft sleeve press-fitting auxiliary mechanism 4 is provided, and the mechanism can be divided into a return spring clamp assembly 401 on the side of the third conveyor belt 301 and a return spring press-fitting assembly 402 on the side away from the third conveyor belt 301. When the workpiece of the return spring C is located at the end of the third conveyor belt 301, the mechanical claw serving as the clamping mechanism 4011 in the return spring clamping assembly 401 is driven by the transfer mechanism 4012 to approach the end of the third conveyor belt 301, and clamps the workpiece of the return spring C, and then the mechanical claw and the clamped and fixed return spring C thereof are driven by the transfer mechanism 4012 to move together to a position opposite to the rotating support shaft B at the station and are locked and fixed. At this time, the spring press-fitting assembly of the return spring C located at the other side of the two first conveyor belts 101 starts to operate, and under the action of the driving main body part 4021, the press-fitting supporting part 4022 approaches to one end of the rotating support shaft B, which is far away from the return spring C, and integrally pushes the rotating support shaft B, so that the rotating support shaft B passes through and is inserted into the hollow part of the return spring C, thereby completing the pre-combined assembly among the roller main body a, the rotating support shaft B and the return spring C.

Specifically, taking the drawings given by the present utility model as an example, the driving body portion 4021 selected here is a cylinder device, and the press-fitting support portion 4022 is a push plate member mounted on a piston rod of the cylinder device. It should be noted that, since the pushing plate is in a planar state and cannot enter the roller body a, a spacer should be disposed between the end of the second conveyor 201 and the end surface of the roller body a erected above the first conveyor 101, so that a part of the rotating support shaft B pushed into the roller body a still protrudes from the side end surface, and the pushing plate is pushed and extruded by the rotating support shaft B when being sleeved with the return spring C. Of course, if the press-fit supporting portion 4022 has a columnar shape capable of entering the hollow area inside the roll body a, the spacer may be omitted.

When the pre-assembly of the roller parts is completed, the clamping mechanism 4011 releases the clamping and locking effect on the return spring C, and the press-mounting support portion 4022 retracts and resets, so that the first conveyor belt 101 continues to move forward and drives the main body part assemblies to move forward and leave the device.

Example 2: in this embodiment, the structural layout of the device is further refined and optimized based on the automatic pre-assembly device for the components of the spring pressing-in roller body a provided in embodiment 1.

First, it is considered that if the roller body a is mounted in a state of being directly held on the first conveyor belt 101, vibration and displacement of the components during press-fitting are liable to be transmitted to the first conveyor belt 101 and cause deformation damage of the components in the transmission mechanism. In order to avoid this, a press-fit auxiliary lifting mechanism 5 capable of lifting the roller body a upward may be installed between the two first conveyor belts 101. The press-fitting auxiliary lifting mechanism 5 also comprises at least one driving cylinder and a lifting part, and a supporting block with the same structure as the supporting block 102 on the first conveying belt 101 can be arranged on the lifting part, and the supporting block can be made of elastic materials such as rubber. By the jacking action of the 5 supporting blocks of the press-fitting auxiliary lifting mechanism, the filtering effect of the vibration action transmitted by the roller body A relative to the first conveying belt 101 can be realized.

Further, in order to adjust and correct the position of the roller body a on the first conveyor belt 101, a position correction pushing assembly 6 for adjusting the lateral position of the roller body a may be provided on the outer side of the first conveyor belt 101, and the correction pushing assembly may be formed by a combination of a cylinder device and a push plate.

Still more preferably, in order to further realize automatic discharging of the roller body a and the rotation supporting shaft B, a roller body feeding device 8a is provided at the front end of the roller body moving and conveying mechanism 1, and a rotation supporting shaft feeding device 8B is provided at the side of the second conveying belt 201. Specifically, the roller body feeding device 8a and the rotating support shaft feeding device 8b each include a plurality of fixing portions 801 and lifting portions 802 that are connected in an inclined manner in sequence, and top surfaces of the fixing portions 801 and the lifting portions 802 are inclined; when one lifting portion 802 is submerged, the top surface of the lifting portion 802 can engage with the top surface of the lower adjacent fixing portion 801, and when the lifting portion 802 is lifted, the top surface of the lifting portion 802 can engage with the top surface of the upper adjacent fixing portion 801. When the roller body a or the rotary support shaft B is used as a lifted workpiece to be placed at the bottom of the device, the lifted workpiece slides inwards under the guiding action of the inclined plane and is clamped between the top surface of the lifting part 802 and the outer wall surface of the last fixing part 801, and along with the lifting of the lifting part 802, the lifted workpiece rises to the top end of the last fixing part 801 along the outer wall surface of the last fixing part 801 and slides to the top of the last lifting part 802 under the guiding action of the inclined plane at the top of the fixing part 801. By repeating the process for a plurality of times, the roller body A or the rotary support shaft B which is used as a lifted workpiece can be lifted from bottom to top, and then enters the respective conveying mechanisms.

Of course, in order to realize automatic feeding of the return spring C, the front end of the return spring feeding and conveying mechanism 3 may be connected with a vibration disc device, and only the discharge port of the vibration disc device is required to be connected with the front end of the third conveying belt 301, so that the return spring C placed inside can be continuously discharged onto the third conveying belt 301 in the opening state of the vibration disc device.

While the utility model has been described with reference to certain preferred embodiments, it will be understood by those skilled in the art that various changes and substitutions of equivalents may be made and equivalents will be apparent to those skilled in the art without departing from the scope of the utility model. Therefore, the protection scope of the utility model is subject to the protection scope of the claims.
