Technical Field
[0001] This utility model relates to the field of machining fixture technology, and in particular to a fixed-distance fixture for shaft cutting. Background Technology
[0002] Shafts are common parts in the mechanical field and are essential in many pieces of equipment. There are usually two ways to process shafts: one is to manufacture shafts directly from raw materials, which is mostly done by manufacturers; the other is to recycle or reprocess shafts purchased from manufacturers. In the second case, the shafts received are often of different lengths, and the processing plant needs to cut them at equal intervals.
[0003] In the process of implementing this solution, the inventors discovered the following problems in the existing technology that have not been well resolved: Although cutting is convenient, the shafts of unequal lengths need to be clamped at a fixed distance during cutting, and each shaft needs to be measured individually during distance measurement, which makes the entire cutting work cumbersome and lengthy, and brings great trouble to the entire processing steps. Utility Model Content

The top of each fixed frame is fixedly connected to the two roller frame mechanisms below it. One of the fixed frames has an adjustment mechanism one at the top end away from the roller frame mechanism, and the other fixed frame has an adjustment mechanism two at the top end away from the roller frame mechanism. A pressing mechanism is provided at the top between the fixed frames.

[0010] The pressing mechanism includes a gantry frame, a hydraulic rod is fixed to the top of the gantry frame, and a pressure plate is fixed to the output end of the hydraulic rod.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] like Figure 1-4 As shown, a fixed-distance fixture for shaft cutting includes a fixed base 1, and there are two fixed bases 1. Two roller frame mechanisms 2 are vertically opposite each other on the top of each fixed base 1. The top of the fixed base 1 is fixedly connected to the two roller frame mechanisms 2 below. One fixed base 1 has an adjustment mechanism 3 at the top away from the roller frame mechanism 2, and the other fixed base 1 has an adjustment mechanism 4 at the top away from the roller frame mechanism 2. A pressing mechanism 5 is provided at the top between the fixed bases 1.
[0025] The roller frame mechanism 2 includes a roller frame base 21, and clamping rollers 22 are fixed at both ends of the top of the roller frame base 21;
[0026] The adjustment mechanism 3 includes a fixed plate 31 and a movable plate 32. The top of the side wall of the fixed plate 31 is threaded with an adjustment screw 33, and the bottom of the side wall of the fixed plate 31 is slidably slidably connected with a slide rod 34.
[0027] Adjustment mechanism 2 4 includes a fixed seat 41 and a movable seat 42. A sliding column 43 slides through the fixed seat 41, and a spring 44 is sleeved on the outer wall of one end of the sliding column 43.
[0028] The pressing mechanism 5 includes a gantry frame 51, a hydraulic rod 52 is fixed at the top inside the gantry frame 51, and a pressure plate 53 is fixed at the output end of the hydraulic rod 52.
[0029] Specifically, the fixed plate 31 is located between the two clamping rollers 22, the adjusting screw 33 passes through one end of the fixed plate 31 and is rotatably connected to the side wall of the moving plate 32, the sliding rod 34 passes through one end of the fixed plate 31 and is fixedly connected to the side wall of the moving plate 32, and the fixed plate 31 is fixed to the top of the fixed base 1.
[0030] Specifically, the movable seat 42 is located between the two clamping rollers 22, the sliding column 43 passes through one end of the fixed seat 41 and is fixedly connected to the side wall of the movable seat 42, and the two ends of the spring 44 are fixedly connected to the side walls of the movable seat 42 and the fixed seat 41 respectively. The fixed seat 41 is fixed to the top of the fixed seat frame 1.
[0031] Specifically, the horizontal lines at the top of the movable plate 32 and the movable seat 42 are higher than the horizontal line at the top of the clamping roller 22, so that the end plate of the shaft can be abutted.
[0032] Specifically, traction rods 54 slide through both ends of the gantry frame 51 located at the hydraulic rod 52. One end of the traction rod 54 passing through the gantry frame 51 is fixedly connected to the roller frame seat 21 of the two upper roller frame mechanisms 2. Springs 55 are sleeved on the outer wall of the traction rod 54 passing through the gantry frame 51. The top of the springs 55 is fixed to the inner top of the gantry frame 51, and the bottom of the springs 55 is fixed to the end of the roller frame seat 21 that is close to it. The two ends of the pressure plate 53 are fixedly connected to the roller frame seat 21 of the two roller frame mechanisms 2, so that the lifting and lowering of the two upper roller frame mechanisms 2 is vertical.
[0033] Working principle:
[0034] The shaft is placed between the two clamping rollers 22 at position 3 of the adjustment mechanism. First, the position of the moving plate 32 is determined. The moving plate 32 is moved horizontally by rotating the adjusting screw 33. One end of the shaft needs to abut against the side of the moving plate 32 away from the fixed plate 31. The distance between the moving plate 32 and the midpoint between the shaft and the fixed seat 1 is determined by abutting against the moving plate 32. The length of the shaft beyond the midpoint to the clamping roller 22 at position 4 of the adjustment mechanism is the excess distance. The moving seat 42 will abut against the other end of the shaft after being pushed by the spring 44, so that the shaft can be initially limited after being fixed. If the length of the shaft changes later, the moving seat 42 can also automatically abut against the other end of the shaft after being pushed out by the tension of the spring 44, unless the length of the shaft is shorter than the required length. However, due to procurement requirements, shafts shorter than the required length will mostly not be purchased or will be used for other purposes.
[0035] After operation, the hydraulic rod 52 drives the two roller frame mechanisms 2 to descend via the pressure plate 53 until the clamping rollers 22 of the upper roller frame mechanism 2 press against the upper two outer walls of the shaft, thereby forming a clamping effect on the shaft in conjunction with the clamping rollers 22 of the two lower roller frame mechanisms 2. Subsequently, the lifting and lowering cutting machine can cut the clamped shaft in a fixed position. After the cutting is completed, the hydraulic rod 52 rises, the two upper roller frame mechanisms 2 move away from the shaft, and the shaft can be removed. When a new shaft needs to be placed, simply pull the moving seat 42 away from the adjusting mechanism 3 to place the new shaft. The operation is simple and convenient.
