Description

Technical Field

[0001] The invention relates to the technical field of worm detection equipment, in particular to a toroidal worm detection equipment. Background Art

[0002] The worm is a commonly used structure in mechanical equipment. After the worm is produced, the annular surface of the worm needs to be inspected and the accuracy of the annular surface of the worm needs to be measured to connect the worm with other mechanical parts. For example, in a tooth surface error detection mechanism of annular worm disclosed in Chinese patent literature (patent number: CN202310169684.7), the fixed seat moves on the transverse support rod, and the detection head detects the worm, but the fixed seat cannot move simultaneously during the detection process of the detection head, and each part of the worm annular surface cannot be detected. The detection head can only be detected again and again by moving the fixed seat. Each movement of the fixed seat and adjustment of the detection head may cause some errors, resulting in the inability to accurately measure the annular surface of the worm.

[0003] To this end, we propose a toroidal worm gear detection device. Summary of the invention

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: during the rotation of the first threaded rod, the slider is driven to move to the right, and the movement of the slider causes the detection pointer to move, thereby continuously detecting the worm annular surface. The detection pointer moves on the worm annular surface, and the torsion spring arranged between the connecting shaft and the measuring table causes the detection pointer to press against the worm annular surface. During the movement of the detection pointer on the worm annular surface, the detection pointer moves, and the detection pointer drives the first connecting rod through the second connecting rod.

The worm ring surface is detected, the worm 2 is placed on the fixed wheel 10 set on the top of the fixed frame 1, and the second threaded rod 12 is rotated. The second threaded rod 12 cooperates with the first threaded hole 14 to drive the lifting plate 13 to move upward. When one end of the pointer 19 contacts the ring surface of the worm 2, it is ensured that the reading of the measuring meter is 0, the second threaded rod 12 is stopped, and the second reduction motor 11 is started. The second reduction motor 11 drives the fixed wheel 1 through the mounting shaft 9. 0 rotates, one end of the fixed wheel 10 is raised, and the worm 2 is fixed between the fixed wheels 10 set on the top of the fixed frame 1. The fixed wheel 10 rotates to drive the worm 2 to rotate, and at the same time, the first reduction motor 7 is started. The first reduction motor 7 drives the first threaded rod 5 to rotate. The middle part of the slider 4 is provided with a threaded hole matched with the first threaded rod 5. During the rotation of the first threaded rod 5, the slider 4 is driven to move rightward. The slider 4 moves to move the detection pointer 19, and the annular surface of the worm 2 is continuously detected. The detection pointer moves on the annular surface of the worm 2. The torsion spring set between the connecting shaft 172 and the measuring meter 171 makes the detection pointer 19 bear against the annular surface of the worm 2. During the movement of the detection pointer 19 on the annular surface of the worm 2, the detection pointer 19 moves. The detection pointer 19 drives the first connecting rod 17 through the second connecting rod 18, and the first connecting rod 17 rotates left and right through the positioning shaft 16. The first connecting rod 19 drives the pointer set on the measuring gauge 171 to jump left and right through the connecting shaft 172. The pointer jumping value range on the measuring gauge 171 is observed to determine whether the annular surface processing of the worm 2 is qualified. The first connecting rod 17 rotates with the positioning shaft 16 as a fulcrum. The length of the first connecting rod 17 and the second connecting rod 18 on the upper part of the positioning shaft 16 is less than the length of the first connecting rod 17 on the lower part of the positioning shaft 16. The error value of the detection pointer 19 in the process of detecting the annular surface of the worm 2 will be amplified and displayed through the measuring gauge 171, thereby more accurately detecting the annular surface of the worm 2.

[0019] Reference embodiment: The lower parts of the left and right sides of the fixing rod 15 are both provided with bayonet 20, the middle of the top of the lifting plate 13 is provided with a mounting groove 21, and the mounting groove 21 is provided with a bearing 22, and the bearing 22 is connected to the bottom end of the fixing rod 15, and the right side of the top of the lifting plate 13 is provided with a fixing block 23, and the middle of the fixing block 23 is provided with a second threaded hole 24, and the second threaded hole 24 is provided with a bolt 25, and the left end of the bolt 25 is provided with a positioning rod 26, and the worm 2 ring surface has two sides. When the detection of one side is completed, the bolt 25 is turned. The bolt 25 cooperates with the second threaded hole 24 to move to the right, driving the positioning rod 26 to disengage from the bayonet 20, and loosening the rotation of the fixing rod 15. After the fixing rod 15 is rotated 180 degrees, the bayonet 20 set on one side of the fixing rod 15 will be aligned with the positioning rod 26. The bolt 25 is rotated in the opposite direction. The bolt 25 drives the positioning rod 26 to move to the left and clamp the bayonet 20, thereby fixing the fixing rod 15, making the detection pointer 19 set on the top of the second connecting rod 18 point to the right, and the annular surface on the other side of the worm 2 is detected.

[0020] Reference embodiment: A bracket 173 is provided at the bottom end of the measuring gauge 171, and the right end of the bracket 173 is fixed on the fixed rod 15. A connecting shaft 172 is provided in the middle of the right side of the measuring gauge 171. A slide groove 174 is provided at the lower part of the first connecting rod 17, and the right end of the connecting shaft 172 extends into the slide groove 174. During the detection process of the annular surface of the worm 2 by the detection pointer 19, there is a processing error in the annular surface of the worm 2, and the detection pointer 19 jumps. The first connecting rod 17 is driven by the second connecting rod 18, and the first connecting rod 17 drives the connecting shaft 172 to rotate, so that the pointer of the measuring gauge 171 connected to one end of the connecting shaft jumps, and the construction error value of the annular surface of the worm 2 is determined.

[0022] Reference embodiment: Two groups of second threaded rods 12 are provided, and the bottom ends of the two groups of second threaded rods 12 are connected to the slider 4 through bearings. The second threaded rods 12 cooperate with the first threaded holes 14. During the rotation of the second threaded rods 12, the lifting plate 13 moves up and down, thereby adjusting the upper and lower heights of the detection pointer 19.

[0023] Reference embodiment: The left end of the first threaded rod 5 is connected to the fixed frame 1 through a bearing, and the right end of the first threaded rod 5 passes through the first through hole 6 and is connected to the first reduction motor 7. The first threaded rod 5 is in the inner surface of the first through hole 6 and no thread is set. The first reduction motor 7 drives the first threaded rod 5 to rotate.
