Description

Technical Field

[0001] The present technical solution relates to the technical field of deep well pumps, and particularly refers to a feeding device for washers and screws of a deep well pump. Background Art

[0002] A deep well pump is a pump device that directly dives into a groundwater well for pumping and transporting water. It usually consists of a pump body, a motor, a cable, etc. Its working principle is that the motor drives the impeller to rotate, and uses centrifugal force to pump water out of the bottom of the well and push it to the ground.

[0003] In the production of existing deep well pumps, after the motor end cover is pressed onto the motor housing, it is necessary to first install a washer into the threaded hole on the motor end cover, and then pass an inner hexagon screw through the threaded hole and tighten it in the hole for further fastening, so that the inner hexagon screw presses on the washer.

[0004] In the existing installation method of washers and screws, after the motor end cover is pressed into the motor housing, the washer is transported to the operator by a conveying component. After manually installing the washer, it is then transported to another operator for screw installation. The installation operations of washers and screws are carried out batch by batch, which requires a large amount of time and more labor input costs, with low production and processing efficiency and cumbersome manual installation operations, and thus needs to be improved. Summary of the Invention

[0005] The present technical solution provides a feeding device for washers and screws of a deep well pump in order to improve the problem of cumbersome manual installation operations of washers and screws of a deep well pump.

[0006] The purpose of the present technical solution is achieved as follows:

[0007] A feeding device for washers and screws of a deep well pump includes a frame, a workbench and an installation table arranged on the frame, and further includes

[0008] a screw feeding device for feeding screws to the feeding device;

[0009] a washer feeding device for feeding washers to the feeding device;

[0010] a feeding device installed on the workbench. The feeding device includes a feeding plate and a feeding driving member. A screw groove and a washer groove are arranged on the feeding plate. The feeding driving member drives the feeding plate to move between a first position and a second position. When the feeding plate is in the first position, the screw groove receives the outlet of the screw feeding device, and the washer groove receives the outlet of the washer feeding device. When the feeding plate is in the second position, the screw groove and the washer groove are ready to receive screws and washers.

[0011] The first material transfer device is slidably arranged on the mounting table and is located above the loading plate; a first fixture for obtaining screws is arranged at the lower part of the first material transfer device, and a first sliding driving member is arranged on the mounting table. The first sliding driving member drives the first material transfer device to slide, so as to drive the screws to be matched with the washers.

[0012] The second assembling device is slidably arranged on the mounting table. A second fixture for obtaining the screw and washer assembly and a tightening device are arranged at the lower part of the second assembling device; a second sliding driving member is further arranged on the mounting table. The second sliding driving member drives the second assembling device to slide, so as to send out the screw and washer assembly from the loading plate, and move it to the motor end cover and then tighten the screw.

[0013] Through the above technical solution, when the deep well pump washer screw loading device is in normal use, when the loading plate is in the first position, the screw feeding device drives the screws to be fed into the screw groove from the discharge port. At the same time, the washer feeding device drives the washers to be fed into the washer groove from the discharge port. The loading driving member drives the loading plate to slide to the second position. At this time, one screw and one washer are ready; the first material transfer device operates to make the first fixture obtain the screws. It slides forward under the drive of the first sliding driving member, moves the screws directly above the washers, and then combines them with the washers to form a whole; the second assembling device drives the second fixture to obtain the screw and washer assembly. It moves forward under the drive of the second sliding driving member until it is located above the motor end cover and aligns with the connection hole of the motor end cover. The screw is passed through the connection hole, and the tightening device immediately tightens the screw and presses the washer, thus completing the connection of the screw and the washer. The automated operation makes the operation more convenient and improves the production efficiency and installation quality.

[0014] Preferably, a first positioning plate and a second positioning plate are arranged on the workbench, and the first positioning plate and the second positioning plate are respectively located on both sides of the workbench along the sliding direction of the loading plate in a one-to-one correspondence.

[0015] One side of the screw groove and the washer groove facing the embedding direction of the screw and the washer penetrates through the side wall of the loading plate to have a feed port. When the loading plate is in the second position, the loading plate is arranged in a dislocation manner relative to the discharge ports of the screw feeding device and the washer feeding device. The first positioning plate and the second positioning plate respectively limit the screws and the washers from separating from the feed port in a one-to-one correspondence.

[0016] Through the above technical solution, a feed port is formed by penetrating the side wall of the feeding plate with the screw groove and the washer groove, so that the feed port can be aligned with the discharge port one by one, facilitating the insertion of the screw and the washer into the two grooves from the side. When the feeding driving member drives the feeding plate to move to the second position, it drives a screw and a nut forward. The feeding plate is arranged offset relative to the discharge ports on both sides, restricting the subsequent entry of screws and nuts. The positioning plate one restricts the screw from disengaging from the screw groove, and the positioning plate two restricts the washer from disengaging from the washer groove, improving the stability of the feeding process and further enhancing the production efficiency.

[0017] Preferably, the screw groove and the washer groove are coaxially arranged, such that the distribution positions of the screw groove and the washer groove are parallel to the sliding direction of the first material transfer device.

[0018] Through the above technical solution, the screw groove and the washer groove are coaxially arranged. After the first material transfer device obtains the screw, based on the consistency between its sliding direction and the axis direction, the sliding driving member one drives the first material transfer device to move back and forth in a single direction, reducing complex alignment or adjustment, and improving the working efficiency and accuracy.

[0019] Preferably, a relief hole is provided at the bottom of the washer groove for the screw rod body of the screw to pass through.

[0020] Through the above technical solution, the size and shape of the relief hole are adapted to the screw rod body of the screw. When the screw is assembled on the washer in the washer groove, the screw rod body can pass through the washer and be placed in the relief hole, providing relief to avoid interference and making the fit between the screw and the washer tighter.

[0021] Preferably, the first material transfer device includes a transfer slide plate slidably arranged on the mounting table, a transfer driving member arranged on the transfer slide plate, and a transfer block;

[0022] The transfer block is arranged on the output shaft of the transfer driving member and is located below the transfer slide plate.

[0023] Through the above technical solution, the sliding driving member one drives the transfer slide plate to slide, thereby driving the transfer driving member and the transfer block to move synchronously, realizing the switching between the positions of the screw groove and the washer groove in the horizontal direction. The transfer driving member drives the transfer block to move up and down in the vertical direction. Based on the first fixture being arranged on the transfer block, it is possible to drive the first fixture to descend, adsorb the screw, and after switching to above the washer groove, the first fixture descends, cancels the adsorption, and assembles the screw and the washer, thus completing the installation operation.

[0024] Preferably, the second assembly device includes an assembly slide plate slidably arranged on the mounting table, an assembly driving member arranged on the assembly slide plate, and an assembly frame;

[0025] The assembly frame is located below the assembly slide plate. The second fixture is arranged on the assembly frame. The assembly driving member drives the assembly frame to move up and down, so as to adsorb the screw and washer assembly into the second fixture.

[0026] Through the above technical solution, the second sliding driving member drives the assembly slide plate to slide, so as to drive the assembly driving member and the assembly frame to move synchronously, realizing the switching between the washer groove and the motor end cover position in the horizontal direction. The assembly driving member drives the assembly frame to move up and down in the vertical direction. Based on the second fixture being arranged on the assembly frame, it is realized that the second fixture is driven to descend, and the screw and washer assembly can be adsorbed. The assembly frame rises and drives the assembly away from the feeding plate. After switching to above the washer groove, the second fixture descends, cancels the adsorption, and makes the screw and washer embed into the motor end cover, preparing for the subsequent tightening operation and further completing the installation operation.

[0027] Preferably, the tightening device includes a rotary cylinder arranged on the assembly frame and a screw head connected to the rotary cylinder, and its rotation axis is parallel to the lifting direction of the assembly frame;
