Description

Technical Field

[0001] The present invention relates to the technical field of lead differences of lead screws, and more specifically, the present invention relates to a measuring tool for lead differences of lead screws. Background Art

[0002] The lead difference of a lead screw refers to a certain error that inevitably exists in the processing of a lead screw or ball screw, which is an important mechanical component as a driving shaft, from a precision perspective, due to the heat treatment process included in production. The precision level specified by JIS is used to qualitatively represent the precision. For the ball screws promoted in the market, the allowable value is set at the C10 level. Generally speaking, the lead screw thread error will accumulate in the positive or negative direction. The method to improve this problem is grinding.

[0003] When measuring with existing measuring tools for lead differences of lead screws, the lead screw is placed inside a clamping plate, and the lead difference of the lead screw is measured by a probe. For lead screws of different specifications, the clamping plate cannot be effectively fixed. When the electric telescopic rod pushes the probe to move, it will cause the workbench to vibrate, resulting in the rolling of the lead screw. In this way, the lead difference data detected by the probe will deviate, and the lead difference of the lead screw cannot be effectively detected. Therefore, how to design a measuring tool for lead differences of lead screws that can prevent the lead screw from rolling during the detection process has become the problem we need to solve currently.

[0041] It should be noted that, among them, the staff first places the lead screw to be detected inside the lead screw clamping plate 7, and the lead screw will squeeze the load-bearing plate 8 to make the load-bearing plate 8 move downward.

A sliding groove 21 for the movable clamping block 20 to move is provided inside the movable support 3. A circular limiting plate 22 for limiting the movable support column 4 is fixedly connected to one side of the movable support column 4.

[0043] It should be noted that among them, the movable clamping block 20 can support the movable support column 4 when placing the lead screw, avoiding the lead screw probe 5 and the movable support column 4 from hindering the placement of the lead screw into the lead screw clamping plate 7. When the lead screw is placed into the lead screw clamping plate 7, the staff can rotate the movable support column 4 to make the movable clamping block 20 enter the sliding groove 21, so that the movable support column 4 drives the lead screw probe 5 to move downward to detect the lead screw, and the circular limiting plate 22 will limit the movable support column 4 to prevent the movable support column 4 from completely falling out of the movable support 3.

[0044] Furthermore, as Figure 6 shown, a support sleeve block 23 for fixing the dust collection box 24 is fixedly connected to the outer wall of the movable support 3. A dust collection box 24 for storing waste chips and dust is fixedly connected to one side of the support sleeve block 23. A dust suction port 25 for discharging waste chips and dust into the dust collection box 24 is communicated with the bottom of the dust collection box 24. The shape of the dust suction port 25 is set to be flared. The flared dust suction port 25 can suck waste chips and dust into the dust collection box 24 over a larger area. As Figure 9 shown, a support member 26 for supporting the transmission rotating column 27 is fixedly connected to the inner wall of the dust collection box 24. A transmission rotating column 27 for driving the rotation of the rotating fan blade 28 to rotate is connected to the inner wall of the support member 26 through a bearing. A rotating fan blade 28 for generating suction after rotation to suck waste chips and dust into the dust collection box 24 is fixedly connected to the outer wall of the transmission rotating column 27. A dust-proof filter screen 29 for preventing waste chips and dust from directly contacting the rotating fan blade 28 is fixedly connected to the inner wall of the dust collection box 24. The dust-proof filter screen 29 is arranged between the dust suction port 25 and the rotating fan blade 28. The top of the transmission rotating column 27 is rotatably connected to a rotating motor 30 for driving the transmission rotating column 27 to rotate. The rotating motor 30 is an MP8085 series high-speed rotating motor device. A motor switch 31 for controlling the opening and closing of the rotating motor 30 is fixedly connected to the top of the rotating motor 30. As Figure 8 shown, a movable rotating plate 32 for driving the corresponding type pressing plate 33 to move is fixedly connected to the top of the movable support column 4. A corresponding type pressing plate 33 for pressing the motor switch 31 after moving is fixedly connected to the bottom of the movable rotating plate 32. The corresponding type pressing plate 33 is arranged on the top of the motor switch 31. A threaded sound-absorbing pipe 34 for absorbing the noise in the dust collection box 24 is fixedly connected to the outer wall of the dust collection box 24. One end of the threaded sound-absorbing pipe 34 is fixedly connected to a noise reduction plate 35 for performing noise reduction processing on the noise transmitted by the threaded sound-absorbing pipe 34.

[0045] It should be noted that after the lead screw is placed in the lead screw clamping plate 7, the operator will rotate the movable support column 4 to insert the movable clamping block 20 into the sliding groove 21, driving the lead screw probe 5 to move downward to detect the lead screw. The movable support column 4 will simultaneously drive the movable rotating plate 32 to rotate, and then drive the movable rotating plate 32 to move downward. The movable rotating plate 32 will drive the corresponding extrusion plate 33 to move, and the corresponding extrusion plate 33 will extrude the motor switch 31, thereby turning on the rotating motor 30. The rotating motor 30 will drive the transmission rotating column 27 to rotate, and the transmission rotating column 27 will drive the rotating fan blade 28 to rotate. The rotating fan blade 28 will generate suction to suck the waste chips and dust on the lead screw into the dust collection box 24 through the dust suction port 25. In this way, the waste chips and dust on the lead screw can be automatically removed during the detection of the lead screw, avoiding the accumulation of waste chips and dust on the lead screw from affecting the detection data during the detection of the lead screw lead difference. At the same time, the rotating motor 30 and the rotating fan blade 28 in the dust collection box 24 will generate noise, and the threaded sound-absorbing pipe 34 will absorb this noise. Then, the threaded sound-absorbing pipe 34 will transmit this noise to the noise reduction plate 35 for noise reduction treatment, avoiding the noise generated by the rotating motor 30 and the rotating fan blade 28 from causing discomfort to the operator.

[0046] Furthermore, as Figure 1 shown, a support column 36 is fixedly connected to the bottom of the workbench 1, and a universal wheel 37 is rotatably connected to the bottom of the support column 36.

[0047] It should be noted that the operator can move the device through the support column 36 and the universal wheel 37, thereby improving the flexibility of the device.

[0048] Working principle: First, the staff places the lead screw to be detected inside the lead screw clamping plate 7. The lead screw will then press against the load-bearing plate 8, causing the load-bearing plate 8 to move downward. The load-bearing plate 8 will drive the threaded slide rod 9 to move downward. The threaded slide rod 9 will cause the threaded rotating ring 11 to rotate through the thread. The threaded rotating ring 11 will drive the transmission gear 12 to move. The transmission gear 12 will engage with the movable rack 13. The movable rack 13 will drive the movable plate 15 to move. The movable plate 15 will drive the movable extrusion column 16 to move. The movable extrusion column 16 will drive the movable extrusion plate 17 to move. The movable extrusion plate 17 will press and fix the lead screw, preventing the lead screw from rolling during the lead pitch difference detection, solving the problem that the detection data deviates due to the rolling of the lead screw caused by vibration during the detection process. And when the movable rack 13 moves, it will drive the movable slider 18 to move. The movable slider 18 will move within the limit groove 19. The movable slider 18 will cooperate with the limit groove 19 to limit the movement of the movable rack 13, preventing the movable rack 13 from shaking and shifting during movement; The movable block 20 can support the movable column 4 when placing the lead screw, avoiding the lead screw probe 5 and the movable column 4 from obstructing the placement of the lead screw inside the lead screw clamping plate 7. When the lead screw is placed inside the lead screw clamping plate 7, the staff can rotate the movable column 4 to make the movable block 20 enter the sliding groove 21, so that the movable column 4 drives the lead screw probe 5 to move downward to detect the lead screw. And the circular limit plate 22 will limit the movable column 4, preventing the movable column 4 from completely falling out of the movable bracket 3; After the lead screw is placed in the lead screw clamping plate 7, the staff will rotate the movable column 4 to insert the movable block 20 into the sliding groove 21 to drive the lead screw probe 5 to move downward to detect the lead screw. The movable column 4 will simultaneously drive the movable rotating plate 32 to rotate, and then drive the movable rotating plate 32 to move downward. The movable rotating plate 32 will drive the corresponding type extrusion plate 33 to move. The corresponding type extrusion plate 33 will press the motor switch 31, thereby turning on the rotating motor 30. The rotating motor 30 will drive the transmission rotating column 27 to rotate. The transmission rotating column 27 will drive the rotating fan blade 28 to rotate. The rotating fan blade 28 will generate suction to suck the waste chips and dust on the lead screw into the dust collection box 24 through the dust suction port 25. In this way, the waste chips and dust on the lead screw can be automatically removed during the lead screw detection, avoiding the accumulation of waste chips and dust on the lead screw from affecting the detection data during the lead pitch difference detection of the lead screw. At the same time, the threaded sound-absorbing pipe 34 will absorb these noises, and then the threaded sound-absorbing pipe 34 will transmit these noises to the noise reduction plate 35 for noise reduction treatment, avoiding the discomfort caused by the noises generated by the rotating motor 30 and the rotating fan blade 28 to the staff; The staff can move this device through the support column 36 and the universal wheels 37, thereby improving the flexibility of this device.
