Examples

As shown in fig. 1 to 5, a wiper blade joint holding device includes: bottom plate 11, roof 12, positioning seat 20 and briquetting 30.

Specifically, the surfaces of the bottom plate 11 opposite to the top plate 12 are all processed with sliding grooves, the sliding grooves are of T-shaped groove structures, the sizes of the sliding grooves of the bottom plate 11 and the top plate 12 are the same, and the positions of the sliding grooves vertically correspond to each other.

Specifically, the positioning seat 20 is slidably disposed in a sliding groove of the bottom plate 11, the positioning seat 20 is provided with a positioning shaft 21, a cylindrical table 22 is disposed at the bottom of the positioning shaft 21, the diameter of the cylindrical table 22 is larger than that of a positioning hole of the wiper connector 1, and the cylindrical table 22 is used for supporting the bottom surface of the wiper connector 1.

Specifically, the spout of roof 12 is located in the slip of briquetting 30, briquetting 30 includes connecting plate 31, connecting plate 31 is equipped with round pin axle 32 perpendicularly, round pin axle 32 cover is equipped with spring 33, spring 33's one end is connected in connecting plate 31, the other end is equipped with clamp plate 34, the processing of polishing is all leveled at the spring 33 both ends, then be connected with connecting plate 31 and clamp plate 34 through the welded mode, round pin axle 32 clearance passes clamp plate 34, structure cooperation through between round pin axle 32 and the clamp plate 34, make clamp plate 34 and connecting plate 31 remain the parallel state throughout, in order to guarantee that clamping-force distributes more evenly.

More specifically, the positioning shaft 21 and the pin shaft 32 are coaxially arranged, and the sum of the length of the positioning shaft 21 protruding out of the cylindrical table 22 and the length of the pin shaft 32 protruding out of the pressing plate 34 after the spring 33 is compressed is less than the depth of the positioning hole of the wiper blade joint 1, so that a gap still exists between the positioning shaft 21 and the pin shaft 32 after clamping; the diameters of the positioning shaft 21 and the pin shaft 32 are smaller than the diameter of the positioning hole of the windscreen wiper joint 1, the positioning shaft 21 and the pin shaft 32 are simultaneously inserted into the positioning hole of the windscreen wiper joint 1 for positioning during clamping, the windscreen wiper joint 1 is prevented from moving, and then the pressing plate 34 is used for pressing downwards. In order to ensure that the positioning shaft 21 and the pin shaft 32 can be smoothly inserted into the positioning hole of the wiper connector 1, chamfer structures are processed on the end surfaces of the positioning shaft 21 and the pin shaft 32.

More specifically, the pressing plate 34 is a circular ring structure, and the outer diameter of the pressing plate is larger than the diameter of the positioning hole of the wiper blade joint.

Preferably, in order to prevent the pressing plate 34 from pressing the wiper blade joint 1 during the clamping process, a pad 35 is disposed on the surface of the pressing plate 34, and the pad 35 is made of a material with low hardness, such as nylon or rubber.

Preferably, in order to widen the application range of the clamping device, the adjusting range of the positioning seat 20 and the pressing block 30 is wider.

The clamping device can be adjusted and moved along the direction of the sliding chute and can also be adjusted and moved in the direction vertical to the sliding chute.

The working principle is as follows: the positioning seat 20 is installed on the bottom plate 11, and the pressing block 30 is installed on the top plate 12, because the wiper support tube comprises 1 connecting tube 2 and two wiper joints 1, two positions of the positioning seat 20 and two corresponding wiper joints 1 of the pressing block 30 are arranged in pairs. Firstly, pre-assembling 1 connecting pipe 2 and one windscreen wiper joint 1, then adjusting the positions of a positioning seat 20 and a pressing block 30 according to the structure of the pre-assembled windscreen wiper supporting pipe, then fixing by using T-shaped screws, wherein the positioning seat 20 and a connecting plate 31 are respectively provided with at least two T-shaped screws, and then sleeving positioning holes of the two windscreen wiper joints 1 on a positioning shaft 21 to enable the bottom surface of the windscreen wiper joint 1 to be in contact with a cylindrical table 22. During punching, the top plate 12 starts to move downwards, the pin shaft 32 is firstly inserted into a positioning hole of the wiper connector 1, then the pad 35 is contacted with the top surface of the wiper connector 1, the pressure is gradually increased along with the downward movement of the top plate 12, the pressing block 30 gradually presses the wiper connector 1, the movement is stopped after the top plate 12 moves downwards to a preset position, at the moment, the clamping work is finished, and then the subsequent punching connection work can be carried out. The spring 33 is not fully compressed after clamping is completed in order to prevent the top plate 12 from moving down insufficiently due to the extreme size of the spring 33 being compressed, thereby affecting subsequent processing.

The foregoing is only a preferred embodiment of the invention and is not intended to be the only or limiting embodiment of the invention. It should be understood by those skilled in the art that various changes and equivalent substitutions made herein may be made without departing from the scope of the invention as defined by the appended claims.
