DETAILED DESCRIPTION

[0024] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0025] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0026] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0027] like Figures 1 to 5A non-standard mechanical parts processing and positioning device shown in the figure includes a workbench 1. A processing mechanism can be externally connected to one side of the workbench 1. The processing mechanism can be selected as a non-standard mechanical parts grinding or other processing mechanism, which can be selected according to actual conditions. The processing mechanism can be externally connected to a hydraulic cylinder, so that the hydraulic cylinder drives the processing mechanism to move back and forth, so that different positions of non-standard mechanical parts can be better processed. A gear 2 is arranged on the top surface of the workbench 1. A driving structure and a fixing structure are arranged on the top surface of the gear 2. A fixing block 12 is fixedly installed on the top surface of the gear 2. The fixing block 12 can be selected to be approximately rectangular in style. A groove 13 is opened on the top surface of the fixing block 12. The driving structure includes a threaded rod 14 rotatably connected to the inner walls on both sides of the groove 13 and a movable block 1 symmetrically threadedly sleeved on the peripheral side of the threaded rod 14. 5, and the two movable blocks 15 are adapted to the inner cavity of the groove 13, the circumferential side of the threaded rod 14 is processed with two threaded teeth in opposite directions, and one end of the threaded rod 14 passes through the fixed block 12 and is fixedly connected with a turning handle, so that the staff can drive the threaded rod 14 to rotate by turning the turning handle, the length of the fixed block 12 is less than the diameter of the gear 2, and the sum of the length of the fixed block 12 and the turning handle is also less than the diameter of the gear 2. The staff turns the turning handle to make the turning handle drive the threaded rod 14 to rotate, so that the threaded rod 14 drives the two movable blocks 15 to move along the circumferential side of the threaded rod 14 and in the inner cavity of the groove 13 in relative or opposite directions, and the bottom surfaces of the two movable blocks 15 are in contact with the bottom surface of the inner cavity of the groove 13, so that the movable blocks 15 will not rotate with the threaded rod 14.

[0028] The top surfaces of the two movable blocks 15 are fixedly mounted with pads 16 for placing non-standard mechanical parts. The movement of the two movable blocks 15 can drive the two pads 16 to move in relative or opposite directions, so that the distance between the two pads 16 can be adapted to non-standard mechanical parts of different sizes, thereby being able to fix non-standard mechanical parts of different sizes. The fixing structure includes two bolts 17 rotatably connected to the top surfaces of the two pads 16 and a pressing plate 18 threadedly sleeved on the sides of the two bolts 17. The styles of the two pads 16 and the two pressing plates 18 can be set to the same Z shape. When non-standard mechanical parts are placed After being placed on the top surfaces of the two pads 16, the bolt 17 is rotated so that the bolt 17 can drive the pressure plate 18 to move up and down, so that the pressure plate 18 can squeeze the non-standard mechanical parts on the top surface of the pad 16, and then squeeze and fix them, which is convenient for subsequent processing. The top surfaces of the two pads 16 and the two sides of the two bolts 17 are fixedly connected with sliding columns 19, and the two pressure plates 18 are respectively sleeved on the peripheral sides of the two sliding columns 19, so that when the pressure plate 18 moves up and down, it will move on the peripheral sides of the two sliding columns 19, so that the two sliding columns 19 can limit the pressure plate 18 to prevent the pressure plate 18 from rotating with the bolts 17.

[0029] The bottom surface of the gear 2 is rotatably connected with a pin shaft 3, and the bottom surface of the pin shaft 3 is fixedly connected to the top surface of the workbench 1, so that the gear 2 can rotate above the workbench 1, thereby being able to drive the driving structure and the fixed structure to rotate, and then the fixed non-standard mechanical parts are rotated. A cross block 4 is fixedly installed on the top surface of the workbench 1 and on one side of the gear 2. The cross block 4 can be set to an approximately rectangular style. The top surface of the cross block 4 and the side surface facing the gear 2 are both provided with a cross groove 5. The two cross grooves 5 are connected through, and the inner cavity of the cross groove 5 is slidably provided with a cross plate 6, and the two side surfaces of the two cross grooves 5 also penetrate the cross block 4, so that the cross plate 6 can enter from the cross groove 5 on one side of the cross block 4 and pass through from the other side of the cross block 4. The side of the cross plate 6 facing the gear 2 is equipped with teeth 7 that are engaged with the gear 2. The radius of the gear 2 is greater than the distance between the pin shaft 3 and the cross block 4, so that one side of the gear 2 The side surface will enter the inner cavity of the transverse groove 5 and engage with the teeth 7. A handle 8 for moving the transverse plate 6 is fixedly installed on the top surface of the transverse plate 6. The handle 8 can be set in different styles for the convenience of the staff to hold. The handle 8 passes through the transverse groove 5 and is arranged above the transverse block 4. The staff can drive the transverse plate 6 to move in the inner cavity of the transverse groove 5 by holding and pushing the handle 8. Since the two side surfaces of the transverse block 4 are through-set, the two side surfaces of the transverse plate 6 can pass through the two side surfaces of the transverse block 4. The movement of the transverse plate 6 will drive the teeth 7 to move, so that the teeth 7 can drive the engaged gear 2 to rotate, so that the gear 2 can drive the driving structure and the fixed structure to rotate, so that non-standard mechanical parts can rotate in a fixed state, and cooperate with the external hydraulic cylinder and processing mechanism to process different positions of the parts, thereby improving the efficiency of processing non-standard mechanical parts.

[0030] The bottom surface of the transverse plate 6 can be connected to a slider 9, and the bottom surface of the inner cavity of the transverse groove 5 can be provided with a slide groove adapted to the slider 9. When the transverse plate 6 moves, the slider 9 will be driven to move in the inner cavity of the transverse groove 5, which can assist the movement of the transverse plate 6 and also limit the transverse plate 6.

[0031] A plurality of through holes 10 are equidistantly provided on one side of the cross block 4 and the cross plate 6. The inner cavities of the two through holes 10 of the cross block 4 and the cross plate 6 are provided with matching plug posts 11. The peripheral sides of the plug posts 11 and the inner walls of each through hole 10 are processed with threaded paths. When the cross plate 6 is moved to a suitable position, the plug posts 11 can be inserted into the two overlapping through holes 10, and the plug posts 11 can be fixed in the two through holes 10 by the self-locking of the thread, so as to fix the position of the cross plate 6 after the movement. The number of the plug posts 11 can be selected according to the actual situation, as long as it can fix the cross plate 6.

[0032] Working principle:

[0033] The non-standard mechanical parts processing and positioning device places the non-standard mechanical parts to be processed on the top surfaces of the two pads 16 and fixes them by the pressing plate 18, which is convenient for subsequent processing. When the position of the parts needs to be adjusted during the processing, the pulling handle 8 is pulled, so that the pulling handle 8 drives the cross plate 6 to move in the inner cavity of the cross groove 5, so that the teeth 7 on one side of the cross plate 6 can drive the embedded gear 2 to rotate, so that the gear 2 can drive the fixed block 12 to rotate, and then drive the two pads 16 to rotate, so that the parts can rotate in a fixed state, and cooperate with the external processing mechanism and the hydraulic cylinder, so that other processing positions of the parts can be moved to the bottom of the processing mechanism, which is convenient for processing and avoids the need for frequent disassembly and assembly to adjust the position of the parts, thereby improving the efficiency of processing non-standard mechanical parts.
