Technical Field

[0001] The invention relates to the technical field of hydraulic or pneumatic assembly equipment, in particular to a rubber buffer block press-assembly equipment. Background Art

[0002] After trimming the flash of the rubber bladder, the functional accessories such as shock absorption, sealing, and inflation begin to be assembled. The first process is to assemble the rubber buffer block, which is assembled at the bottom layer inside the closed end of the bladder (such as Figure 1 shown).

[0003] The existing process is: a fixture frame with a cylinder, the front end of the cylinder piston rod is connected to the fixed fixture of the rubber buffer block, and the bottom of the fixture frame is equipped with a fixture for placing the product (skin bag) (such as Figure 2 As shown). The buffer block is installed in the tooling (buffer blocks of different specifications share one tooling, and the ball head adjustment plunger screw outside the circumference of the tooling is adjusted to lock the buffer block), and then the product is installed on the bottom tooling (the staff places the center based on experience), the cylinder is started, the buffer block is driven down, and pressed into the bottom of the bladder. However, it often happens that the buffer block is not assembled in place and cannot cooperate with the bladder or is not pressed in place, or the entire product is pulled up and dumped out of the lower tooling after pressing, resulting in unqualified quality inspection problems at the customer's site after delivery. At the same time, the debugging time for changing different buffer blocks is 20 minutes, which affects production efficiency. Summary of the invention

[0004] In order to solve the technical problems existing in the background technology, the present invention provides a rubber buffer block press-fitting device.

[0005] The present invention provides a rubber buffer block press-fitting device, which is used to press the buffer block into a bladder, and comprises a frame, on which a buffer block tooling is installed through a top lifting mechanism;

[0006] The buffer block tooling has a receiving groove for receiving the buffer block and opening downward, wherein an adsorption portion for adsorbing the buffer block by negative pressure is provided in the receiving groove;

[0007] The top of the buffer block tooling is provided with a detection column, the detection column has a portion extending to the receiving groove, the detection column has a portion located above the buffer block tooling, when the adsorption portion adsorbs the buffer block to the receiving groove, the buffer block squeezes the detection column and moves the detection column upward, and also includes a detection member installed on the top lifting mechanism, the detection member is used to detect the displacement of the detection column moving upward, specifically, the detection member is a laser displacement sensor;

[0008] The detection posts and the detection members are provided with at least two groups, one group of the detection posts corresponds to one group of the detection members, and at least two groups of the detection posts and the detection members are used to detect whether the buffer block is tilted in the vertical direction in the accommodating groove.

The suction cup is connected to a vacuum air inlet connector, and the vacuum air inlet connector is connected to an existing vacuum generator or other vacuum equipment. When the buffer block needs to be placed, the buffer block is pushed into the receiving groove, and the adsorption part sucks the buffer block, and the buffer block pushes the detection column upward. The detection part is used to detect the displacement of each detection column. If the displacement of at least two detection columns is unequal, the buffer block is not horizontal in the receiving groove (i.e., it is offset in the vertical direction), and then the relevant staff makes corresponding adjustments.

[0010] As a further optimized solution of the present invention, a plurality of openings connected to the accommodating grooves are opened on the outer side of the buffer block tooling, and a limiting portion is formed between any two adjacent openings, which further facilitates observation and adjustment of the position of the buffer block.

Specifically, the end of the adjusting plunger opposite to the buffer block is hemispherical.

[0013] As a further optimized solution of the present invention, the detection column is located at the periphery of the adsorption portion to further increase the detection accuracy.

[0014] Specifically, the detection column is an elastic column pin.

[0015] As a further optimized solution of the present invention, the detection column includes a sleeve installed on the buffer block fixture, the top of the buffer block fixture is provided with a detection through hole, the detection through hole is connected to the middle hole of the buffer block fixture sleeve and forms a stepped hole, the aperture of the detection through hole is smaller than the aperture of the middle hole of the sleeve, the detection through hole and the sleeve form a first stepped surface, the first stepped surface is located on the buffer block fixture, the detection column also includes a sliding column, the sliding column vertically includes an upper column and a lower column formed in one piece, of course, the upper column and the lower column can be fixed by welding, the outer diameter of the upper column is larger than the outer diameter of the lower column, a second stepped surface is formed between the upper column and the lower column, and an elastic member is provided between the second stepped surface and the first stepped surface. The elastic member can be a spring.

[0016] As a further optimized solution of the present invention, when the sliding column is not under stress, the elastic member is in a compressed state under the weight of the upper column, and when the buffer block is adsorbed into the accommodating groove, the bottom of the lower column slides into the detection through hole, and the elastic member is in an extended state.

Users can replace different buffer block tooling according to actual buffer block requirements.

[0019] As a further optimized solution of the present invention, the top of the detection column is provided with an extension plate, the outer diameter of the extension plate is larger than the outer diameter of the detection column, and the detection member is opposite to the extension plate, thereby ensuring that the position of the detection column on different buffer block tooling can be detected without changing the installation position of the detection member.

[0020] As a further optimized solution of the present invention, a connecting hole is opened on the connecting seat, and a connecting column is provided on the top of the buffer block tooling. The connecting column matches the connecting hole, and the axis of the connecting column coincides with the axis of the accommodating groove. Preferably, the connecting column is fixed in the connecting hole by a locking screw.
