Description

Technical Field

[0001] The utility model relates to the technical field of plowshares, in particular to a tool used for increasing the wear resistance of the plowshares. Background Art

[0002] The plow shovel is a part of the plow in agricultural machinery and is mainly used for tillage operations.

[0003] At present, after the plow shovel has undergone form quenching and overall tempering, in order to further increase the wear resistance of the plow shovel, the plow shovel is usually clamped and fixed with tooling, and then the easily worn parts such as the plow shovel tip and two wings are locally quenched, thereby effectively improving the service life of the plow shovel.

[0004] However, in the prior art, the clamping blocks in the tooling for clamping and fixing the plow shovel are usually horizontal plates. During local quenching, the plow shovel may easily rotate and displace due to collisions, thereby causing deviations in the quenched position. Therefore, the utility model proposes a tooling for increasing the wear resistance of the plow shovel to solve the above problem. Utility Model Content

[0005] The purpose of the utility model is to provide a tooling for increasing the wear resistance of a plowshare, so as to solve the problem in the above-mentioned background technology that when the plowshare is locally quenched, it is easy for the plowshare to rotate and displace when the tooling clamp is a horizontal plate when it is hit, thereby causing deviation of the local quenching part.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a tool for increasing the wear resistance of a plow shovel, the tool for increasing the wear resistance of a plow shovel comprising:

[0007] A workbench, one side of the workbench is fixedly connected with a mounting seat, one end of the mounting seat is slidably connected with a positioning block, a spring is fixedly connected between the positioning block and the mounting seat, one end of the workbench is rotatably plugged with a screw driven by a motor, one end of the screw is threadedly sleeved with an upper clamping plate, one end of the upper clamping plate is plugged with a fixed guide rod, the fixed guide rod is fixedly connected to the workbench, one side of the upper clamping plate is fixedly connected with four fixing rods distributed in a circular array with the center of the positioning block as the center, and the multiple fixing rods are all inclined toward the center of their circular array.

[0008] Preferably, one end of the positioning block is arranged in a "conical" shape and the other end of the positioning block is fixedly connected with a sliding block, and the sliding block is fixedly connected to a spring and slidably connected to a mounting seat.

[0009] Preferably, one end of the mounting seat is provided with a mounting groove for sliding installation of the slider, and one side of the mounting seat is fixedly connected with two lower clamping blocks symmetrically arranged with the positioning block as the center.

[0010] Preferably, one end of the screw rod is fixedly connected to a limiting block, and the upper clamping plate is located between the limiting block and the workbench.

[0011] Preferably, a threaded hole and a positioning hole are penetrated through one side of the upper clamping plate, the screw rod and the upper clamping plate are threadedly inserted in the threaded hole, and the fixed guide rod and the upper clamping plate are slidably inserted in the positioning hole.

[0012] Preferably, a plurality of the fixing rods are fixedly connected with fixing blocks, and the fixing blocks are arranged in a cross shape.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The device initially positions the plow shovel on the mounting seat by plugging the positioning block and the rectangular connecting hole of the plow shovel, and then controls the upper clamp plate to slide downward, thereby driving a plurality of fixing rods on the upper clamp plate that are distributed in a circular array and inclined to slide down together. The center of the circular array of the plurality of fixing rods coincides with the center of the positioning block. Therefore, as the upper clamp plate slides down, the fixing rod will push the positioning block to slide into the mounting seat, and the plurality of fixing rods will be inserted into the rectangular connecting holes of the plow shovel, and then the plow shovel will be clamped and fixed by cooperating with the mounting seat. In this way, not only can the plow shovel be fixed with less space, making it more convenient to perform local quenching of the plow shovel, but the plow shovel can also be effectively prevented from rotating left and right when clamped in the upper and lower positions, thereby solving the problem that when the plow shovel is locally quenched, it is easy to cause the plow shovel to rotate and displace when the tooling clamp block is a horizontal plate and is hit, thereby causing deviation of the local quenching part.

[0024] Embodiment 1, a tool for increasing the wear resistance of a plow shovel, the tool for increasing the wear resistance of a plow shovel comprises: a workbench 1.

[0025] Specifically, one side of the workbench 1 is fixedly connected to a mounting seat 6, one end of the mounting seat 6 is slidably connected to a positioning block 7, a spring 72 is fixedly connected between the positioning block 7 and the mounting seat 6, one end of the workbench 1 is rotatably plugged with a screw rod 2 driven by a motor 21, one end of the screw rod 2 is threadedly sleeved with an upper clamping plate 3, one end of the upper clamping plate 3 is plugged with a fixed guide rod 9, the fixed guide rod 9 is fixedly connected to the workbench 1, one side of the upper clamping plate 3 is fixedly connected with four fixed rods 4 distributed in a circular array with the center of the positioning block 7 as the center, and multiple fixed rods 4 are inclined toward the center of their circular array. In actual implementation, first, the shaped plow shovel and the positioning block 7 are slidably sleeved, so that the position of the plow shovel is initially fixed, and then the motor 21 drives the screw rod 2 to rotate, thereby driving the upper clamping plate 3 to slide in the direction of the plow shovel. The sliding of the clamping plate 3 will drive the multiple fixing rods 4 to contact with the positioning block 7, and will push the positioning block 7 to slide toward the end of the mounting seat 6, and then the multiple fixing rods 4 will slide and insert into the rectangular connecting hole of the plow shovel, and then as the plow shovel and the mounting seat 6 contact, finally, with the cooperation of the multiple fixing rods 4 and the mounting seat 6, the plow shovel can be clamped and fixed in the up and down directions, and the plow shovel can also be limited from rotating left and right with the cooperation of the rectangular plow shovel connecting hole, thereby further ensuring the stability of the plow shovel installation and the accuracy of the position of the plow shovel during quenching. In this way, the shovel tip and two wings of the plow shovel, which are in worn positions, can be better exposed, making it easier to operate during quenching, and the fixed guide rod 9 can prevent the upper clamping plate 3 from rotating when it is driven by the screw rod 2 to slide, thereby ensuring the corresponding positions of the fixing rod 4 and the positioning block 7.

[0026] In order to further improve the adaptability of the positioning block 7, one end of the positioning block 7 of the present application is set in a "conical" shape and the other end of the positioning block 7 is fixedly connected to a slider 71. The slider 71 is fixedly connected to a spring 72 and is slidably connected to the mounting seat 6. The "conical" positioning block 7 can adapt to more sizes of plow shovel connection holes, and the slider 71 can better limit the tilting of the positioning block 7.

[0027] In order to facilitate the sliding installation of the positioning block 7, one end of the mounting seat 6 of the present application is provided with an installation groove 61 for the sliding installation of the slider 71, and one side of the mounting seat 6 is fixedly connected to two lower clamping blocks 8 symmetrically arranged with the positioning block 7 as the center. The installation groove 61 can facilitate the fixed rod 4 to push the positioning block 7 to slide, and the lower clamping block 8 can suspend the plow shovel in the air, thereby better cooperating with multiple fixed rods 4 to clamp and fix the plow shovel.

[0028] In order to prevent the upper clamping plate 3 from detaching from the screw rod 2, one end of the screw rod 2 of the present application is fixedly connected to a limit block 22, and the upper clamping plate 3 is located between the limit block 22 and the workbench 1. The limit block 22 can limit the upper clamping plate 3 to ensure that the upper clamping plate 3 does not slide out of the screw rod 2.

[0029] In order to better install the upper clamping plate 3, a threaded hole 31 and a positioning hole 32 are penetrated on one side of the upper clamping plate 3 of the present application. The screw rod 2 and the upper clamping plate 3 are threadedly inserted into the threaded hole 31, and the fixed guide rod 9 and the upper clamping plate 3 are slidably inserted into the positioning hole 32, so that the upper clamping plate 3 and the screw rod 2 and the fixed guide rod 9 can be easily connected.

[0030] In order to further enhance the stability of the fixed rods 4 , the multiple fixed rods 4 of the present application are fixedly connected with fixed blocks 5 , and the fixed blocks 5 are arranged in a “cross” shape. The “cross” shaped fixed blocks 5 can further enhance the connection between the four fixed rods 4 , thereby enhancing the overall stability of the four fixed rods 4 .

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
