Technical Field

[0002] Cylindrical materials refer to materials that are similar in shape to a cylinder, usually hollow, and their cross-sections are mostly circular. Common examples of such materials include pipes, bearings, screws, pipe fittings, etc. When turning the materials, the materials need to be fixed.

The lower surface of the positioning plate 23 is set as an inclined surface, and the inclined surface of the lower surface of the positioning plate 23 is set at the left position of the lower surface of the positioning plate 23. By squeezing the inclined surface of the lower surface of the positioning plate 23, the positioning plate 23 will move upward. The upper surface of the positioning plate 23 is set as an inclined surface, and the inclined surface of the upper surface of the positioning plate 23 is set on the left and right sides of the upper surface of the positioning plate 23.

[0035] Reference Figure 1 - Figure 3 The positioning assembly also includes a motor 22. The motor 22 is a prior art and can be implemented by technicians in this field.

The positioning wheel three 37 will roll along the upper surface of the positioning plate 23. When the positioning plate 23 moves upward, it will squeeze the positioning wheel three 37 to make the positioning wheel three 37 roll, and the connecting rod 33 will rotate with the center of the circle of the rotating shaft 32 as the axis. The rotating connecting rod 33 and the upward moving positioning plate 23 will drive the positioning wheel two 36 and the positioning wheel one 34 to approach each other, so that the cylindrical material placed on the positioning wheel two 36 can be clamped and fixed.

[0038] Reference Figure 1 , Figure 3 and Figure 4 , connecting rod 33, block 38, positioning wheel 1 34, connecting block 31, rotating shaft 32, positioning wheel 37, and block 38 are provided in two groups, and the two groups of connecting rod 33, positioning wheel 1 34, connecting block 31, rotating shaft 32, positioning wheel 37, and block 38 are symmetrically distributed along the center line of positioning plate 23, and the two groups of blocks 38 are elastically connected by compression springs 39, one end of the compression spring 39 is fixedly connected to the left surface of the block 38, and the other end of the compression spring 39 is fixedly connected to the right surface of the other group of blocks 38. When the positioning plate 23 moves upward, the distance between the two positioning wheels 37 will increase, which will drive the block 38 to move and stretch the compression spring 39 to generate a reaction force. When the positioning plate 23 returns to its original position, the connecting rod 33, block 38 and positioning wheel 37 will be reset under the pull of the reaction force of the compression spring 39.

[0039] Reference Figure 1 and Figure 6 The limiting assembly includes a support plate 41, the inner wall of the support plate 41 is elastically connected to the limiting plate 44 through a limiting spring 43, the left surface of the limiting plate 44 passes through and is fixedly connected to the limiting rod 42, the limiting rod 42 can fix the position of the support plate 41, and when the support plate 41 moves laterally, it will drive the positioning assembly and the clamping assembly to move synchronously, and a limiting groove 401 is opened on the left surface of the lathe 1.

[0040] Reference Figure 1 and Figure 6 The motor 22 is arranged on the upper surface of the support plate 41, the support plate 41 is slidably connected to the left surface of the lathe 1, the limit plate 44 is slidably connected to the inner wall of the support plate 41, one end of the limit spring 43 is fixedly connected to the left surface of the limit plate 44, and the other end of the limit spring 43 is fixedly connected to the inner wall of the left side of the support plate 41. When the limit plate 44 moves to the left, it will squeeze the limit spring 43 to generate a reaction force. The limit rod 42 is inserted into the inner wall of the limit slot 401. When the limit rod 42 moves to the left, it will disengage from the limit slot 401 to release the limit.

[0041] Working principle: when it is necessary to turn a cylindrical material, first install the material on the lathe 1, and then fix the material. When fixing, start the motor 22 to drive the threaded rod 27 to rotate, and the rotating threaded rod 27 will drive the slide plate 25 to move to the right. The slide plate 25 moving to the right will contact the positioning plate 23, and squeeze the inclined surface at the bottom end of the positioning plate 23 to move the positioning plate 23 upward. The positioning plate 23 moving upward will squeeze the positioning wheel three 37 to make the positioning wheel three 37 roll along the inclined surface of the upper surface of the positioning plate 23. When the positioning wheel three 37 rolls, it will drive the connecting rod 33 to rotate with the center of the rotating shaft 32 as the origin.

[0042] The rotating connecting rod 33 will drive the positioning wheel 1 34 to approach the material. When the positioning wheel 1 34 and the positioning wheel 2 36 on both sides clamp the cylindrical material, the motor 22 is turned off. Under the influence of the self-locking property of the threaded rod 27, the position of the device will be fixed, thereby maintaining the stability of the device when clamping the cylindrical material. When the positioning plate 23 rises and drives the positioning wheel 3 37 to roll, the distance between the two groups of blocks 38 will also be expanded. When the distance between the two groups of blocks 38 is expanded, the compression spring 39 will be stretched to generate a reaction force. After the material is fixed, processing begins.

[0043] After the processing is completed, the processed material needs to be removed. When removing the material, first adjust the switch of the motor 22 to change the direction of rotation of the output shaft of the motor 22, so that the output shaft of the motor 22 rotates in the opposite direction, and then start the motor 22 to drive the threaded rod 27 to rotate in the opposite direction. The threaded rod 27 rotating in the opposite direction will drive the slide plate 25 to move to the left, and the slide plate 25 moving to the left will gradually separate from the positioning plate 23. After the positioning plate 23 and the slide plate 25 separate, they will move downward to release the squeezing of the positioning wheel three 37. After the squeezing is released, the connecting rod 33 will be driven to rotate in the opposite direction under the influence of the tensile force of the reaction force of the compression spring 39, so that the clamping assembly returns to its initial position, the clamping of the material is released, and then the material is removed.

[0044] Since the lengths of the materials are of different sizes, in order to maintain stability during processing, the clamping assembly and the positioning assembly need to be adjusted to the middle section of the material. When adjusting, first pull the limit rod 42 to the left to drive the limit plate 44 to move to the left. The limit plate 44 moving to the left will squeeze the limit spring 43 to generate a reaction force. The limit plate 44 moving to the left will disengage from the limit groove 401 to release the limit on the support plate 41, and then move the support plate 41 back and forth to drive the clamping assembly and the positioning assembly to move synchronously. When moving to the appropriate position, release the limit rod 42, and the reaction force of the limit spring 43 will push the limit plate 44 and the limit rod 42 to move to the right. The limit rod 42 moving to the right will be plugged into the limit groove 401 to limit the support plate 41, thereby ensuring the stability of the device.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
