Description

Technical Field

[0001] The utility model relates to the technical field of stud processing, in particular to a thread rolling machine which can prevent the stud from rotating. Background Art

[0002] Studs are a type of fastener that has no head and only external threads on both ends. In the processing of external threads on studs, they need to be fixed on a thread rolling machine. The traditional fixing method is to clamp and fix the stud rod with a structure similar to a vise, but the surface of the stud is arc-shaped, and the contact area with the vise is small when clamped and fixed. The stud rod will not rotate at will without being subjected to a large external force. However, under the action of the machine rotating the thread rolling, the force exerted by the machine on the stud rod is very large. Therefore, if the stud rod is only fixed with a clamping structure, the stud rod can easily rotate with the rotation of the machine, which affects the accuracy of the stud thread rolling. Finally, there is a large error in the external thread processed, which affects the actual use of users.

DETAILED DESCRIPTION

[0026] The following will be combined with the attached embodiment of the utility model Figure 1-4, clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0027] A thread rolling machine capable of preventing a stud from rotating comprises a base 1, a bottom plate 12 being fixedly mounted on the inner side of the base 1, a movable platform 2 being movably arranged on the top of the bottom plate 12, a slide rail 3 being fixedly connected to one side of the top of the movable platform 2, a bidirectional screw 4 being rotatably mounted inside the slide rail 3, a hand-cranked wheel 17 being detachably mounted on one end of the bidirectional screw 4, a sliding member 5 sliding on the surface of the slide rail 3 being threadedly mounted on both sides of the surface of the bidirectional screw 4, a clamping arm 6 being fixedly connected to the top of the sliding member 5, a stud member 7 being arranged between the two clamping arms 6, a clamping block 10 being fixedly connected to the bottom of the inner sides of the two clamping arms 6, and a clamping block 8 being fixedly connected to one end of the inner sides of the two clamping arms 6.

[0028] The specific usage process is as follows: first, the user needs to put the stud member 7 on the thread rolling machine for fixing, and the operation is as follows: the user turns the hand crank wheel 17, and the hand crank wheel 17 drives the bidirectional screw 4 to rotate. Because the two sliding members 5 are installed on the bidirectional screw 4 in a threaded connection, and the threads on the bidirectional screw 4 are distributed in two parts, and the threads of the two parts are set in opposite directions, when the bidirectional screw 4 rotates, the two sliding members 5 will move in opposite directions. At the same time, the two sliding members 5 still slide on the slide rail 3, so that under the limiting effect of the slide rail 3, the two sliding members 5 will not rotate with the rotation of the bidirectional screw 4, so the two sliding members 5 move in opposite directions, and then the sliding members 5 will also Drive the clamping arms 6 to move backwards. When the two clamping arms 6 are separated by a suitable distance, the user puts the stud piece 7 between the two clamping arms 6, and then the user rotates the hand-cranked wheel 17 in the opposite direction, and then the bidirectional screw 4 rotates in the opposite direction. At this time, the two sliding members 5 and the two clamping arms 6 will move toward each other, and the two sliding members 5 will slide on the slide rail 3, and then the two clamping arms 6 will clamp the stud piece 7. It should be noted that in this process, the user needs to control the stud piece 7 to not move. As the two clamping arms 6 gradually approach, the block 1 8 on the clamping arm 6 will be inserted into the corresponding slot 1 9. At the same time, the position of the stud piece 7 should be adjusted so that the two block 2 10 should also be inserted into the slot 2 11. In this way, between the block 1 8, the slot 1 9, With the cooperation of the second clamping block 10 and the second clamping slot 11, the stud member 7 can be positioned between the two clamping arms 6, and then the user continues to rotate the hand wheel 17, the two will continue to move toward each other, and finally the stud member 7 is clamped and fixed. In this way, with the restrictions of the first clamping block 8 and the second clamping block 10, the stud member 7 will not rotate with the thread rolling machine, which can ensure the accuracy of the thread rolling processing of the stud member 7, and ensure that in actual use, the stud member 7 can match the corresponding components, providing convenience for the user's work. When the stud member 7 is fixed, the user rotates the hand wheel 21, the hand wheel 21 drives the hand wheel 2 18 to rotate, and the hand wheel 2 18 drives the gear 19 to rotate, because the gear 19 is meshed with the toothed plate 20, And the tooth plate 20 is fixed, so the gear 19 will also roll on the tooth plate 20 when it rotates, so that the movable platform 2 can be driven to move and adjust on the bottom plate 12, which provides convenience for the thread rolling work of the stud. Then the user continues to control the movable platform 2 to move in the direction of the thread rolling device 22, and then the end of the stud member 7 will enter the thread rolling device 22 to realize the processing of the surface thread of the stud member 7. When the thread of one end of the stud member 7 is processed, the stud member 7 is removed and the direction is reversed and fixed again between the two clamping arms 6, and then it is sent into the thread rolling device 22 for thread rolling processing according to the above-mentioned operating steps, thereby completing the processing of all external threads of the stud member 7, improving the accuracy of the thread processing of the stud member 7, and providing convenience for the user's work.

[0029] Therefore, a structural design that can fix the stud in place is adopted. On the basis of a single clamping structure, a structure for positioning the stud is added, so that the stud will not rotate with the rotation of the machine during the thread rolling process, thereby improving the accuracy of the stud thread rolling process, improving the quality of the stud processing, and providing convenience for users' work.

[0030] A second clamping groove 11 matched with two second clamping blocks 10 is provided on one side of the bottom of the stud member 7 , and a first clamping groove 9 matched with a first clamping block 8 is provided on one end of both sides of the stud member 7 .

A sliding block 15 is slidably installed inside the long opening 14 . One side of the sliding block 15 is fixedly connected to the moving platform 2 .

[0033] Specifically, the setting of the limiting guide rail 13, the long opening 14 and the sliding block 15, when the mobile platform 2 moves, it will drive the sliding block 15 to slide in the long opening 14, so that the limiting guide rail 13 and the long opening 14 will limit the movement of the sliding block 15, and then can also limit the mobile platform 2, thereby improving the stability of the mobile platform 2 when moving, and providing convenience for the user's work.

[0034] A fixed rail 16 is fixedly connected to one side of the top of the bottom plate 12 , and a slide groove is provided on one side of the bottom of the moving platform 2 , and the fixed rail 16 is slidably installed in the slide groove.

[0035] Specifically, the fixed rail 16 and the slide groove are arranged such that the slide groove is opened on the mobile platform 2, the fixed rail 16 is fixed on the bottom plate 12, and the fixed rail 16 is slidably installed in the slide groove, so that the fixed rail 16 can limit the movement of the mobile platform 2, further improve the stability of the mobile platform 2 when moving, and provide convenience for the user's work.

[0036] A toothed plate 20 is fixedly connected to the top of the bottom plate 12 , a rotating rod is provided through one side of the moving platform 2 , and a gear 19 meshing with the toothed plate 20 is fixedly installed at one end of the rotating rod 18 .

[0037] Specifically, the setting of the rotating rod 18, the gear 19 and the toothed plate 20 is that the user drives the rotating rod 18 to rotate by turning the hand-cranked wheel 21, and the rotating rod 18 drives the gear 19 to rotate. Because the gear 19 is meshed with the toothed plate 20, and the toothed plate 20 is fixed, the gear 19 will also roll on the toothed plate 20 when rotating, so that the movable platform 2 can be driven to move and adjust on the bottom plate 12, which provides convenience for the thread rolling work of the stud.

[0038] A hand-cranked wheel 21 is fixedly mounted on one end of the rotating rod 18 , and a thread rolling device 22 is disposed on one side of the base 1 .

[0039] Specifically, the setting of the hand-cranked wheel 21 is the same as the hand-cranked wheel 17, and is used for the user to grasp. In this way, the user can drive the rotating rod 18 to rotate by turning the hand-cranked wheel 21, thereby finally realizing the adjustment and movement of the mobile platform 2, providing convenience for the user's work.
