Description

Technical Field

[0001] This utility model relates to the field of boss processing technology, specifically a positioning device for boss processing. Background Technology

[0002] A boss is a structural feature typically used in specific parts of mechanical components. In part drawings, a boss is depicted as an outward-protruding shape, the size and shape of which depend on the specific application requirements. During the machining of a boss, a positioning device is required to position it.

[0003] However, existing positioning devices position the boss by moving the positioning plates on the left and right sides to contact the outer wall of the boss.

[0004] However, existing positioning devices only locate the left and right sides of the boss when positioning it, and cannot locate the front and back of the boss. This may cause the front and back positions of the boss to deviate, thereby reducing the positioning accuracy of the existing positioning device for the boss. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a positioning device for machining bosses, which solves the problem that existing positioning devices can only position the left and right sides of the boss and cannot position the front and back of the boss, thus reducing the positioning accuracy of existing positioning devices for bosses.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning device for machining bosses, comprising a positioning table, a positioning plate disposed above the positioning table, and a positioning mechanism disposed inside the positioning table. The positioning mechanism includes: a rack penetrating the surface of the positioning table and movably connected to it; a gear meshing with the outer wall of the rack; a turntable fixedly connected to the inner wall of the gear and rotatably connected to the inner wall of the positioning table via a pin; a connecting column rotatably connected to the inner wall of the turntable via a pin; a sliding groove formed in the inner wall of the positioning table; a vertical column rotatably connected to the inner wall of the connecting column via a pin, slidingly engaging with the inner wall of the sliding groove, and fitting against the outer wall of the positioning plate; and an auxiliary component disposed inside the positioning table. The gear, driven by the rack, causes the turntable to move the connecting column, which in turn moves the positioning plate, simultaneously positioning the four sides of the boss. The auxiliary component limits the movement of the rack.

[0007] Preferably, the auxiliary component includes: a threaded post, threadedly connected to the inner wall of the positioning platform; a knob, fixedly connected to one end of the threaded post; a crank post, rotatably connected to the other end of the threaded post via a bearing; and a friction plate, fixedly connected to the end of the crank post; wherein, when the knob is driven, the threaded post causes the crank post to drive the friction plate to contact the surface of the rack, thereby limiting and locking it.

[0008] Preferably, a slider is fixedly connected to the outer wall of the curved column, and a slide rod is slidably engaged with the inner wall of the slider, the slide rod being fixedly connected to the inner wall of the positioning platform.

[0009] Preferably, a connecting block is fixedly connected to the outer wall of the positioning platform, and the inner wall of the connecting block is provided with an installation hole.

[0010] Preferably, the vertical column is fixedly connected to a positioning plate by screws, and a rubber pad is fixedly connected to the surface of the positioning plate.

[0011] Preferably, a positioning block is fixedly connected to the surface of the vertical column, and a positioning hole is inserted into the outer wall of the positioning block, the positioning hole being opened in the inner wall of the positioning plate. Beneficial effects

[0012] This utility model provides a positioning device for machining bosses. It has the following advantages: This positioning device for machining bosses, through the cooperation of a rack, gear, turntable, connecting column, vertical column, and slide groove, achieves simultaneous positioning of all four sides of the boss. This solves the problem that existing positioning devices only position the left and right sides of the boss, failing to position the front and back, thus reducing the positioning accuracy of existing devices.

[0013] By using the coordination between the knob, threaded rod, crank, friction plate, slider, and slide bar, the rack is limited and locked, thus solving the problem that the gear might rotate after the rack has finished moving because the rack and gear cannot achieve self-locking.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Existing positioning devices only locate the left and right sides of the boss when positioning it, and cannot locate the front and back of the boss, thus reducing the positioning accuracy of existing positioning devices for the boss.

[0022] In view of this, the present invention provides a positioning device for machining bosses. Through the cooperation between rack, gear, turntable, connecting column, vertical column and slide groove, the four sides of the boss are positioned simultaneously. This solves the problem that the existing positioning device can only position the left and right sides of the boss and cannot position the front and back of the boss, thus reducing the positioning accuracy of the existing positioning device.

[0023] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly introduced below.

[0024] Example 1, by Figure 1-5As can be seen, the positioning device for machining bosses in this case includes a positioning table 1. The operator places the boss on the positioning table 1. Positioning plates 5 are installed above the positioning table 1, and the boss is positioned by four positioning plates 5. A positioning mechanism 2 is installed inside the positioning table 1. The positioning mechanism 2 includes: a rack 21, which passes through the surface of the positioning table 1 and is movably connected to it; the operator pulls the rack 21, causing it to move within the positioning table 1; a gear 22, which is meshed with the outer wall of the rack 21, causing it to rotate; a turntable 23, which is fixedly connected to the inner wall of the gear 22, causing it to rotate; and a connecting column 24. The rotating pin is connected to the inner wall of the turntable 23, which drives the connecting column 24 to rotate. The slide groove 26 is opened on the inner wall of the positioning platform 1. The vertical column 25 is connected to the inner wall of the connecting column 24 via the pin. The connecting column 24 drives the vertical column 25 to move and slides into the inner wall of the slide groove 26. The vertical column 25 moves in the slide groove 26 and drives the positioning plate 5 to move and fits against the outer wall of the positioning plate 5. The auxiliary component 27 is set inside the positioning platform 1. The gear 22 drives the rack 21 to drive the turntable 23 to move the connecting column 24, which in turn drives the positioning plate 5 to move, and simultaneously positions the four sides of the boss. The auxiliary component 27 limits the rack 21.

[0025] In the specific implementation process, it is worth noting that the staff places the boss on the positioning table 1, pulls the rack 21, the rack 21 moves in the positioning table 1, the rack 21 drives the gear 22 to rotate, the gear 22 drives the turntable 23 to rotate, the turntable 23 drives the connecting column 24 to rotate, the connecting column 24 drives the vertical column 25 to move, the vertical column 25 moves in the slide groove 26, and the vertical column 25 drives the positioning plate 5 to move. The boss is positioned by the four positioning plates 5. After the positioning is completed, the staff stops pulling the rack 21. When the staff pushes the rack 21, the four positioning plates 5 return to the initial position, realizing the simultaneous positioning of the four sides of the boss.

[0026] Furthermore, the auxiliary component 27 includes: a threaded post 272 threadedly connected to the inner wall of the positioning table 1; a knob 271 fixedly connected to one end of the threaded post 272, the knob 271 driving the threaded post 272 to rotate; a crank post 273 rotatably connected to the other end of the threaded post 272 via a bearing, the threaded post 272 driving the crank post 273 to move; and a friction plate 274 fixedly connected to the end of the crank post 273, the crank post 273 driving the friction plate 274 to move. The friction plates 274 on both sides contact the surface of the rack 21. When the knob 271 drives the threaded post 272, the crank post 273 drives the friction plate 274 to contact the surface of the rack 21, limiting and locking it.

[0027] In the specific implementation process, it is worth noting that after the rack 21 has moved, the operator rotates the knob 271. The knob 271 drives the threaded column 272 to rotate, the threaded column 272 drives the crank column 273 to move, and the crank column 273 drives the friction plate 274 to move. The friction plates 274 on both sides contact the surface of the rack 21. After this is completed, the operator stops rotating the knob 271. When the rack 21 needs to move, the operator rotates the knob 271 in the opposite direction. The friction plate 274 leaves the surface of the rack 21, and the rack 21 moves. This achieves the limitation and locking of the rack 21 by the friction force of the friction plate 274.

[0028] Furthermore, a slider 2731 is fixedly connected to the outer wall of the curved column 273. The curved column 273 drives the slider 2731 to move. A slide rod 2732 is slidably engaged with the inner wall of the slider 2731. The slider 2731 moves on the slide rod 2732. The slide rod 2732 is fixedly connected to the inner wall of the positioning platform 1.

[0029] In the specific implementation process, it is worth noting that when the crank column 273 moves, the crank column 273 drives the slider 2731 to move, and the slider 2731 moves on the slide rod 2732 to limit the crank column 273.

[0030] Specifically, first, the worker places the boss on the positioning table 1. Then, the worker pulls the rack 21, which moves within the positioning table 1. The rack 21 drives the gear 22 to rotate, which in turn drives the turntable 23 to rotate. The turntable 23 then drives the connecting column 24 to rotate, which in turn drives the vertical column 25 to move. The vertical column 25 moves within the slide groove 26, which in turn drives the positioning plates 5 to move. The boss is positioned using the four positioning plates 5. After positioning, the worker stops pulling the rack 21. When the worker pushes the rack 21 back, the four positioning plates 5 return to their initial positions. At the starting position, after completion, the operator rotates knob 271, which drives threaded column 272 to rotate. Threaded column 272 drives crank column 273 to move, crank column 273 drives slider 2731 to move, slider 2731 moves on slider 2732, and crank column 273 drives friction plate 274 to move. The friction plates 274 on both sides contact the surface of rack 21. After completion, the operator stops rotating knob 271. When rack 21 needs to move, the operator rotates knob 271 in the opposite direction, and friction plates 274 leave the surface of rack 21, moving rack 21.

[0031] Example 2, by Figure 2 , 3As can be seen from 5, the outer wall of the positioning table 1 is fixedly connected to the connecting block 3. The workers fix the positioning table 1 to the external processing equipment through the mounting holes 4 on the connecting block 3. There are four connecting blocks 3 and four mounting holes 4. The inner wall of the connecting block 3 is provided with mounting holes 4.

[0032] In the specific implementation process, it is worth noting that the staff fixes the positioning table 1 to the external processing equipment through the mounting holes 4 on the connecting block 3. There are four connecting blocks 3 and four mounting holes 4.

[0033] Furthermore, the vertical column 25 is fixedly connected to the positioning plate 5 by screws 51. The operator can replace the positioning plate 5 by rotating the screws 51, and replace it with positioning plates 5 of different shapes to position the bosses of different shapes. The surface of the positioning plate 5 is fixedly connected with a rubber pad 52, which protects the bosses and prevents the surface of the bosses from showing the marks of the positioning plate 5.

[0034] In the specific implementation process, it is worth noting that the staff can replace the positioning plate 5 by rotating the screw 51, and replace it with a positioning plate 5 of different shapes to position the bosses of different shapes. The rubber pad 52 protects the bosses and prevents the surface of the bosses from having traces of the positioning plate 5.

[0035] Furthermore, a positioning block 53 is fixedly connected to the surface of the vertical column 25. The positioning plate 5 drives the positioning hole 54 to move, and the positioning hole 54 is inserted into the positioning hole 54. The positioning hole 54 is inserted into the outer wall of the positioning block 53, and the positioning hole 54 is opened on the inner wall of the positioning plate 5.

[0036] In the specific implementation process, it is worth noting that when the positioning plate 5 is moved, the positioning plate 5 drives the positioning hole 54 to move, and the positioning hole 54 is inserted into the positioning hole 54 to achieve quick positioning of the positioning plate 5 for replacement.

[0037] Specifically, the operator fixes the positioning table 1 to the external processing equipment through the mounting hole 4 on the connecting block 3. The operator can replace the positioning plate 5 by rotating the screw 51, replacing it with a positioning plate 5 of different shapes to position the bosses of different shapes. When the positioning plate 5 is moved, the positioning plate 5 drives the positioning hole 54 to move, and the positioning hole 54 is inserted into the positioning hole 54. The rubber pad 52 protects the boss and prevents the surface of the boss from having the marks of the positioning plate 5.
