Description

Technical Field

[0001] The utility model relates to the technical field of bolts, in particular to a double-headed bolt processing and positioning device. Background Art

[0002] Bolts are a commonly used fastener, which usually consists of a head and a screw. They are used to fasten and connect two parts with through holes. According to different standards and uses, bolts can be divided into many types, such as ordinary bolts, high-strength bolts, anchor bolts, expansion bolts, chemical anchors, etc. Each type of bolt has its specific application scenarios and characteristics.

[0003] In addition to single-head bolts, stud bolts that can be connected at both ends have appeared on the market. During the production and processing of stud bolts, a processing positioning device is required to keep the semi-finished cylinder in a stable state, avoid shaking during the production process, and avoid waste of materials.

[0004] The processing positioning devices used on the market mostly adopt a V-shaped buckle structure.

[0033] The following will be combined with the drawings in the embodiments of the utility model to 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 the embodiments. Based on the embodiments in 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.

[0034] See also Figures 1 to 9 , the utility model provides a technical solution:

[0035] A stud bolt processing and positioning device comprises a frame assembly 1, wherein a rack slide 3 is fixedly mounted on the upper end of the frame assembly 1, a rack 4 is mounted on the right side of the rack slide 3, a chassis 5 is fixedly mounted on the upper end of the frame assembly 1, a hexagonal slide 51 is provided on the upper end of the chassis 5, an extrusion block 6 is movably mounted inside the hexagonal slide 51, a slide column 61 is fixedly mounted at the center position of the upper straight edge of the extrusion block 6, a slide table 62 is fixedly mounted at the center position of the lower straight edge of the extrusion block 6, the slide table 62 is slidably mounted inside the hexagonal slide 51, a toothed disc ring 7 is rotatably mounted on the upper end of the chassis 5, a toothed disc ring 7 is provided on the circumferential surface of the toothed disc ring 7, the toothed disc ring 7 is meshed with the rack 4, a connecting hole 72 is provided on the toothed disc ring 7, and the slide column 61 slides inside the connecting hole 72.

[0036] By adopting the above technical solution, the processing and positioning devices on the market mostly use V-shaped interface buckles to fix, clamp and position the semi-finished cylinder. However, when the V-shaped buckle is in operation, the construction personnel need to rotate the threaded rod multiple times so that the V-shaped buckle can fit the lower end of the semi-finished cylinder, thereby fixing the semi-finished cylinder. In order to avoid the situation where the V-shaped buckle is shaking and cannot be clamped, the friction between the lower end of the V-shaped buckle and the slide groove is relatively large when the lower end of the V-shaped buckle is slidably connected. In order to enable the lower end of the V-shaped buckle to slide, lubricating fluid is added to the inside of the slide groove to allow the V-shaped buckle to move. This type of method requires regular addition of lubricant to the inside of the slideway, and because the metal will wear, the equipment needs to be disassembled and maintained regularly. Since the slideway is fixedly installed, disassembly is relatively time-consuming. The structure of this device is as follows: a through hole with a circular structure is opened at the center of the base 11, and a chassis 5 is fixedly installed on the upper end surface of the base 11, wherein a through hole with a circular structure is also opened at the center of the chassis 5, and the diameter of the through hole on the base 11 is the same as that of the through hole on the chassis 5, and a hexagonal slide 51 is opened on the upper end surface of the chassis 5, and the upper end of the chassis 5 is rotated to install A toothed disc ring 7 is installed, wherein the lower end of the toothed disc ring 7 is a concave structure, therefore, the upper end of the chassis 5 is located inside the groove of the toothed disc ring 7, and six connecting holes 72 are opened on the toothed disc ring 7; six triangular extrusion blocks 6 are installed between the toothed disc ring 7 and the chassis 5, and a slide column 61 is fixedly installed at the center position of the straight edge of the upper end surface of the extrusion block 6, wherein the slide column 61 extends to the inside of the connecting hole 72, and in addition, a slide table 62 is fixedly installed at the center position of the straight edge of the lower end of the extrusion block 6, and the slide table 62 is slidably installed inside the hexagonal slide groove 51, wherein the lower end slide tables 62 of the six extrusion blocks 6 correspond to the six A side groove 51, a tooth groove 71 is provided on the outer circumferential surface of the gear disk ring 7; secondly, a rack groove 3 is fixedly installed on the upper end surface of the base 11, and a rack 4 is slidably installed inside the rack groove 3, and the rack 4 is meshed with the tooth groove 71. During the sliding process of the rack 4, the gear disk ring 7 can rotate forward and backward, and then, driven by the connecting hole 72, the center of the extrusion block 6 combination can be in an open or closed state; the frame assembly 1 includes a base 11, a vertical plate 12, and a convex groove 13, the vertical plate 12 is fixedly installed at the upper rear part of the base 11, and the convex groove 13 is provided at the front end of the vertical plate 12.

[0037] When in use, push the rack 4 to slide inside the rack slide groove 3. When the rack 4 slides, the rack 4 can make the tooth groove 71 rotate clockwise with the gear ring 7, and when the gear ring 7 rotates clockwise, the connecting hole 72 can move synchronously with the sliding column 61, and the sliding column 61 will move synchronously with the extrusion block 6 during its movement. At this time, the extrusion block 6 will slide with the slide 62 inside the hexagonal slide groove 51. At this time, the center position of the six extrusion blocks 6 will gradually become a cylinder with a hexagonal structure. Until the extrusion block 6 can no longer slide, the gear ring 7 will be forced to stop rotating, thereby making the extrusion block 6 in a stopped state. Then, place the semi-finished cylinder that needs to be rolled on the upper end surface of the support plate 81, and then follow the above steps to make the rack 4 rotate counterclockwise with the gear ring 7. At this time, the extrusion block 6 will be reset driven by the connecting hole 72 on the toothed disc ring 7. During the resetting process, the extrusion block 6 can fix and support the semi-finished cylinder inside, so that the semi-finished cylinder remains in the center position, and then the semi-finished cylinder is in a positioned state; in summary, with the cooperation of the structure, the semi-finished cylinder can be processed and positioned, so that the semi-finished cylinder will be placed in the center position in the end no matter what, thereby further avoiding the displacement of the semi-finished cylinder. Moreover, during the use of the above structure, the rack 4 can directly slide out from the inside of the rack slide groove 3, and then the toothed disc ring 7 can be removed, and finally the construction personnel can directly remove the extrusion block 6. This structure reduces the use of bolts and rivets for important components when they are in use, making the subsequent disassembly of the structure extremely simple and quick.

[0038] Specifically, Figures 1 to 9As shown, the frame assembly 1 also includes a U-shaped groove 14, a height hole 141, and a placement hole 142. The placement hole 142 is opened in the middle of the upper end of the base 11. The U-shaped groove 14 is opened at the upper end of the base 11 and is located at the front and rear ends of the placement hole 142. The height hole 141 is opened on the rear end inner wall of the U-shaped groove 14; a plurality of U-shaped slide boxes 15 are fixedly installed on the opening edge of the U-shaped groove 14, and two springs 151 are fixedly installed inside the U-shaped slide box 15, and a support plate 16 is fixedly installed on the right end of the spring 151; a drive assembly 2 is installed on the upper end of the frame assembly 1, and the drive assembly 2 includes a drive motor 21 and a screw 22. The upper end of the screw 22 is fixedly connected to the output shaft of the driving motor 21, and the lower end of the screw 22 extends to the base 11; a movable plate 24 is slidably installed on the circumferential surface of the screw 22, and the rear end of the movable plate 24 is slidably installed inside the convex slide groove 13; two servo motors 23 are fixedly installed on the upper end of the movable plate 24, and a thread rolling shaft 25 is fixedly installed on the lower end output shaft of the servo motor 23; a connecting rod 8 is installed inside the U-shaped groove 14, and a support plate 81 is fixedly installed on the circumferential surface of the connecting rod 8, the rear end of the connecting rod 8 is installed inside the height hole 141, and the front end of the connecting rod 8 is placed on the support plate 16.

[0039] By adopting the above technical solution, during use, the output shaft of the driving motor 21 rotates with the screw 22, and the driving motor 21 can rotate forward and reverse, so the screw 22 can adjust the direction as the output shaft rotates. Secondly, during the rotation of the screw 22, the movable plate 24 on its circumferential surface will rotate synchronously, but under the restriction of the convex slide groove 13, the movable plate 24 can only move up and down; during the movement of the movable plate 24, it can move synchronously with the servo motor 23, and the servo motor 23 is vertically fixed on the upper end surface of the movable plate 24, and the output shaft of the servo motor 23 passes through the movable plate 24 and is fixedly installed with a thread rolling shaft 25; the output shafts of the two servo motors 23 The thread rolling shaft 25 is rotated in different directions, and then driven by the movable plate 24, the thread rolling shaft 25 can fit with the circumferential surface of the semi-finished cylinder, so that the thread rolling operation can be carried out; with the cooperation of the above structure, thread rolling operations at different heights can be achieved, while most thread rolling devices on the market are fixedly connected, so that when operating, the semi-finished cylinder needs to be adjusted in height before the operation can be carried out, and the process is relatively slow. In addition, during use, the semi-finished cylinder is placed between two thread rolling cylinders. During the process of removing the semi-finished cylinder after the operation is completed, if the operator is not careful, the completed bolt will fall off from the hands of the construction worker under the action of the thread rolling shaft 25, thereby causing damage to equipment or personnel.

[0040] Working principle: First, slide the rack 4, so that the rack 4 and the toothed disc ring 7 rotate clockwise. When the toothed disc ring 7 rotates clockwise, the extrusion block 6 can move in the same direction, so that a hexagonal column will appear in the center of the extrusion block 6, and one end of the semi-finished cylinder is placed on the support plate 81;

[0041] Then, the above steps are performed in reverse order to allow the extrusion block 6 to clamp and position the semi-finished cylinder inside so that the semi-finished cylinder is in the center, thereby allowing the equipment to complete the processing and positioning at one time.

[0042] After completing the processing and positioning of the semi-finished cylinder, start the servo motor 23, the output shaft of the servo motor 23 rotates the thread rolling shaft 24, and then the output shaft of the driving motor 21 rotates the screw 22, so that the movable plate 25 moves up and down, and then the thread rolling operation is performed on the upper end of the semi-finished cylinder.

[0043] After completion, perform the same operation on the other end of the semi-finished cylinder according to the above steps to produce a stud bolt at the interface.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
