DETAILED DESCRIPTION
[0014] The utility model is further described below in conjunction with the accompanying drawings.
[0015] Example: Figure 1 , Figure 2 , Figure 3 As shown, a fixing tool for processing the ear hole of a yoke shaft comprises a mounting platform 1, a placing piece 2 and a locking piece 3. The mounting platform 1 is arranged horizontally as a whole, and a slide groove 11 is arranged in the middle of its upper surface along its length direction. The placing piece 2 is a square structure as a whole, and is located at the right end of the upper surface of the mounting platform 1. Threaded through holes are arranged at the four corners of its upper surface. Threaded connecting rods 21 are passed through the threaded through holes, and a limiting connection between the placing piece and the mounting platform 1 is achieved through the threaded connecting rods 21. A placing groove 22 is arranged at the center of the left side surface of the placing piece 2 along its length direction. The placing groove 22 is cylindrical as a whole, and its structure matches the structure of the yoke shaft tube; the locking piece 3 is located on the mounting platform The left side of the platform 1 includes a fixed plate 31, a sliding plate 32 and a locking connecting plate 33. A sliding block is fixedly provided at the lower end of the sliding plate 32 and is slidably connected to the slide groove 11 through the sliding block. The fixed plate 31 is arranged parallel to the left side of the sliding plate 32, and its lower end is fixedly connected to the upper surface of the mounting platform 1, and an electric push rod 34 is fixedly provided transversely between the fixed plate 31 and the sliding plate 32. The locking connecting plate 33 is transversely arranged at the upper end of the right side of the sliding plate 32, one end of which is vertically fixedly connected to the sliding plate 32, and a locking block 35 is provided at the center of the other end, and a material receiving baffle 36 is longitudinally fixedly provided above the locking connecting plate 33, and a calibration limit block 37 is longitudinally fixedly provided below.
[0016] The outer sleeve of the threaded connecting rod 21 is provided with a fine-tuning gasket 23, and the fine-tuning gasket 23 is located between the placement piece 2 and the mounting platform 1. With this structure, the fine-tuning gasket 23 of different thicknesses can be used to complete the fine adjustment of the vertical height of the placement piece 2, so that the center of the side placement groove 22 and the center of the locking block 35 are located in the same horizontal plane; the outer end face of the locking block 35 is a semicircular structure, and a calibration groove 24 is horizontally arranged in the middle of the front end face of the placement piece 2. The locking block 35 of this structure, in conjunction with the setting of the calibration groove 24, can be used to quickly observe and judge whether the center of the locking block 35 and the center of the placement groove 22 are located in the same horizontal plane; the right side face of the calibration limit block 37 is an arc as a whole, and its width gradually decreases from top to bottom. Compared with the square structure, the calibration limit block 37 of this structure can play a certain buffering effect in the process of calibrating the position of the fork end of the yoke shaft.
[0017] Before using the utility model, it is necessary to observe whether the center of the locking block 35 and the center of the calibration groove 24 are located in the same horizontal plane. If they are located in the same horizontal plane, the threaded connecting rod 21 is locked and the threaded connecting rod 21 is used to realize the limiting connection between the placement piece 2 and the mounting platform 1. If they are not located in the same horizontal plane, the fine-tuning gasket 23 is replaced. By using fine-tuning gaskets 23 of different thicknesses, the vertical height of the placement piece 2 is finely adjusted so that the center of the locking block 35 and the center of the calibration groove 24 are located in the same horizontal plane; at this point, since the placement groove 22 and the calibration groove 24 are both located in the middle of the placement piece 2, their centers are located in the same horizontal plane. Therefore, by observing whether the center of the locking block 35 and the center of the calibration groove 24 are located in the same horizontal plane, it can be determined whether the center of the locking block 35 and the center of the placement groove 22 are located in the same horizontal plane.
[0018] When the utility model is in use, first, the yoke shaft to be processed is placed horizontally on the side end of the placement member 2 by utilizing the matching sleeve connection between the placement groove 22 and the yoke shaft tube, and then, the electric push rod 34 is controlled to expand, and the expansion of the electric push rod 34 is utilized to cooperate with the sliding connection between the slider below the sliding plate 32 and the sliding groove 11, and the sliding plate 32 and the locking connecting plate 33 can be driven to move horizontally and horizontally while the electric push rod 34 is expanded, and the movement of the locking connecting plate 33 can drive the locking block 35 and the calibration limit block 37 to move, and with the movement of the locking block 35, after its outer end is in close contact with the inner bottom surface of the yoke shaft fork end, it can cooperate with the placement member 2 to lock and limit the yoke shaft placed horizontally and horizontally on the side end of the placement member 2, and at the same time, with the movement of the calibration limit block 37, the longitudinally arranged calibration limit block 37 can be moved At the same time, the angle of the yoke shaft fork end is extruded and calibrated so that the ear hole processing positions on both sides of the yoke shaft fork end are respectively located directly above and directly below the locking connecting plate 33. After the lower surface of the calibration limit block 37 contacts the inner surface of the yoke shaft fork end, the longitudinally arranged calibration limit block 37 can be used to calibrate and limit the yoke shaft fork end, thereby ensuring the verticality of the ear hole processing and avoiding the problem of angle deviation caused by relative rotation between the yoke shaft and the placement piece 2 during the subsequent drilling process, thereby affecting the accuracy of the ear hole processing. In addition, the utility model provides a material receiving baffle 36, which can not only protect the locking connecting plate 33 but also receive iron filings generated during the drilling process. In general, the utility model has the advantages of good use effect and precise and convenient adjustment operation.
