Description

Technical Field

[0001] The utility model relates to the technical field of milling fixtures, in particular to a milling fixture for a right box body. Background Technique

[0002] Milling is to fix the blank, and use a high-speed rotating milling cutter to feed on the blank to cut out the required shapes and features. Traditional milling is mostly used for milling simple external features such as contours and grooves. CNC milling machines can perform the processing of complex external shapes and features. Milling and boring machining centers can perform three-axis or multi-axis milling and boring processing, and are used for processing, molds, inspection tools, tooling fixtures, thin-walled complex curved surfaces, artificial prostheses, blades, etc.

[0003] When milling the right box body, it is necessary to clamp and limit the right box body. The usual clamping method is to fix it through a cylinder or directly fix it on the machine tool with bolts. However, these clamping methods all have certain defects and cannot realize the pushing away of the right box body after processing. Personnel still need to go to the fixed position to pick up the right box body, which poses a safety hazard to the staff. Content of the Utility Model

[0004] The purpose of the utility model is to provide a milling fixture for a right box body to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A milling fixture for a right box body, including a machine tool, a box body main body, a transmission belt, a pulley and a handle. A rotating rod is arranged on the machine tool. A pulley is arranged at one end of the rotating rod. The transmission belt is sleeved on the pulley. The other end of the rotating rod is connected with a handle. The other end of the transmission belt is sleeved on the pulley of a bidirectional lead screw. Clamping plates are respectively threadedly connected to the bidirectional lead screw. A worm is arranged in the middle of the bidirectional lead screw. The worm is meshed and connected with a worm gear. A rack is arranged in the output direction of the worm gear. A push plate is arranged at the output end of the rack. The push plate is located on one side of the box body main body.

[0006] Preferably, a limiting rod is arranged on the machine tool on one side of the bidirectional lead screw. Corresponding clamping plates are slidably connected to the limiting rod. The clamping plates are respectively located above and below the limiting rod.

[0007] Preferably, the limiting rod is vertically arranged on the machine tool. The limiting rod is parallel to the bidirectional lead screw on one side. A fixing frame is arranged on the machine tool on one side of the bidirectional lead screw.

[0008] Preferably, a sliding opening is formed on the fixing frame. A rack is slidably connected in the sliding opening of the fixing frame. The rack is horizontally slidably connected to the fixing frame.

[0009] Preferably, a bracket is provided on the fixing frame. The bracket and the fixing frame are integrally arranged in an L shape. The bracket is arranged obliquely, and a connecting rod is rotatably connected to the bracket.

[0010] Preferably, the connecting rod is horizontally rotatably connected to the bracket. One end of the connecting rod is arranged on the worm gear, and a gear is arranged on the other end of the connecting rod. The gear is meshed and connected to the rack.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] By arranging a bidirectional lead screw on the machine tool, the bidirectional lead screw is vertically arranged on the machine tool. One end of the bidirectional lead screw is located below the machine tool. A pulley is installed on the end of the bidirectional lead screw below the machine tool. The pulley of the bidirectional lead screw is on the same side as the pulley on the rotating rod. A transmission belt can be sleeved on the two pulleys. When the rotating rod is rotated, the bidirectional lead screw can be driven to rotate through the transmission of the transmission belt. When the bidirectional lead screw rotates, the clamping plates on the upper and lower sides of the bidirectional lead screw will approach or move away from each other. When they approach each other, the upper and lower sides of the box body can be clamped and limited. The box body can then be milled. When the clamping plates approach each other, the rack will drive the push plate away from the box body. When the clamping plates move away from the box body, the rack will drive the push plate to push the box body. The box body will then move away from the fixed position under the push of the push plate, thus facilitating the staff to take and protect the staff.

[0013] By arranging a fixing frame on the machine tool, a sliding opening can be opened on the fixing frame. A rack can be installed inside the sliding opening of the fixing frame. The rack can move within the limit of the sliding opening and will not shift during movement, thus ensuring that the rack can drive the push plate to push the box body. A bracket is installed on the fixing frame, and a connecting rod is installed on the bracket. The connecting rod can maintain its position unchanged under the limit of the bracket and will rotate at the position of the bracket. One end of the connecting rod is connected to a worm gear, and the other end of the connecting rod is connected to a gear. The gear is meshed and connected to the rack, and the worm gear is meshed and connected to a worm. The worm is arranged on the bidirectional lead screw. When the bidirectional lead screw rotates, it will drive the worm to rotate. When the worm rotates, it will drive the worm gear to rotate. When the worm gear rotates, it will drive the gear to rotate. The gear will drive the rack to move, and the rack will drive the push plate to move, thereby realizing that when the fixture moves away from the box body, the push plate pushes the box body away.

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: a right box body milling fixture, including a machine tool 1, a box body main body 2, a transmission belt 4, a belt pulley 5 and a handle 7. A rotating rod 6 is provided on the machine tool 1. A belt pulley 5 is provided at one end of the rotating rod 6. The transmission belt 4 is sleeved on the belt pulley 5. The other end of the rotating rod 6 is connected to a handle 7. The other end of the transmission belt 4 is sleeved on the belt pulley 5 of the bidirectional lead screw 8. Clamping plates 3 are respectively threadedly connected to the bidirectional lead screw 8. A worm 9 is provided in the middle of the bidirectional lead screw 8. The worm 9 is meshed and connected to a worm gear 15. A rack 13 is provided in the output direction of the worm gear 15. The output end of the rack 13 is provided with a push plate 11. The push plate 11 is located on one side of the box body main body 2. When the rotating rod 6 is rotated, the bidirectional lead screw 8 can be driven to rotate through the transmission of the transmission belt 4. When the bidirectional lead screw 8 rotates, the clamping plates 3 on the upper and lower sides of the bidirectional lead screw 8 will approach or move away from each other. When approaching each other, the upper and lower sides of the box body main body 2 can be clamped and limited. When the clamping plates 3 approach each other, the rack 13 will drive the push plate 11 to move away from the box body main body 2. When the clamping plates 3 move away from the box body main body 2, the rack 13 will drive the push plate 11 to push the box body main body 2. The box body main body 2 will move away from the fixed position under the push of the push plate 11, which facilitates the staff to pick up and also protects the staff.

[0021] When the bidirectional lead screw 8 rotates, the worm 9 will be driven to rotate. When the worm 9 rotates, the worm gear 15 will be driven to rotate. When the worm gear 15 rotates, the gear 17 will be driven to rotate, and the rack 13 will drive the push plate 11 to move, so as to realize that when the fixture moves away from the box body main body 2, the push plate 11 pushes the box body main body 2 away.

[0022] On one side of the bidirectional lead screw 8 on the machine tool 1, a limit rod 10 is provided. A corresponding clamping plate 3 is slidably connected to the limit rod 10, and the clamping plates 3 are respectively located on the upper and lower sides of the limit rod 10. By providing the limit rod 10 on the machine tool 1, the limit rod 10 will limit the clamping plate 3. When the clamping plate 3 is limited by the limit rod 10, it will not rotate with the rotation of the bidirectional lead screw 8, thereby ensuring that the clamping plate 3 can move along the bidirectional lead screw 8.

[0023] The limit rod 10 is vertically arranged on the machine tool 1. The limit rod 10 is parallel to the bidirectional lead screw 8 on one side. A fixed frame 12 is provided on the machine tool 1 on one side of the bidirectional lead screw 8. By providing the fixed frame 12, the limit of the rack 13 can be realized, and the rack 13 can move on the fixed frame 12.

[0024] A sliding opening 18 is formed on the fixed frame 12. A rack 13 is slidably connected in the sliding opening 18 of the fixed frame 12, and the rack 13 is horizontally slidably connected to the fixed frame 12. By forming the sliding opening 18 on the fixed frame 12, the rack 13 can be installed in the sliding opening 18. The rack 13 will be limited by the sliding opening 18, and the rack 13 will move horizontally under the guidance of the sliding opening 18. The rack 13 will not deviate from the direction during movement, thereby ensuring that the rack 13 can drive the push plate 11 to move towards or away from the position of the box body main body 2, so as to realize the pushing of the box body main body 2.

[0025] A support 14 is provided on the fixed frame 12. The support 14 and the fixed frame 12 are integrally arranged in an L shape. The support 14 is arranged obliquely, and a connecting rod 16 is rotatably connected to the support 14. By installing the support 14 on the fixed frame 12, the connecting rod 16 can be installed on the support 14, and the connecting rod 16 will rotate at the position of the support 14, and the connecting rod 16 will not deviate during rotation.

[0026] The connecting rod 16 is horizontally rotatably connected to the support 14. One end of the connecting rod 16 is arranged on the worm gear 15, and the other end of the connecting rod 16 is provided with a gear 17, and the gear 17 is meshed and connected to the rack 13. By providing a worm 9 on the bidirectional lead screw 8, the worm 9 can be meshed with the worm gear 15. When the worm 9 rotates following the bidirectional lead screw 8, it will drive the meshed worm gear 15 to rotate. The worm gear 15 is linked with the gear 17 through the connecting rod 16. When the worm gear 15 rotates, the gear 17 will also rotate. When the gear 17 rotates, it will drive the meshed rack 13 to move horizontally, thereby ensuring that the rack 13 can drive the push plate 11 to move horizontally.

[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
