Description

Technical Field

[0001] This utility model relates to the field of screw processing technology, and in particular to a positioning device for screw processing of an electric screw press. Background Technology

[0002] Chinese patent document CN219485613U discloses a widely applicable positioning fixture for screw machining. This invention solves the problem in existing technologies where material debris may fall during screw machining. Due to gravity, this debris falls into the fixture, requiring regular cleaning to ensure its proper use. However, the limited space inside the fixture makes this cleaning process time-consuming, thus restricting the fixture's practical application and hindering its versatility. The newly designed positioning fixture for screw machining includes a worktable. The worktable has fixed seats on both sides of its inner cavity, and cylinders are mounted on the top of the fixed seats. This invention eliminates the need for manual cleaning of debris falling into the worktable during use.

[0003] When the aforementioned positioning fixture for screw processing clamps a long screw, it lacks sufficient support for the middle position of the screw. Since the processing equipment generates downward squeezing force when it comes into contact with the screw, the screw may be slightly bent, affecting the yield rate of screw processing. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning device for the screw processing of an electric screw press, which can solve the problem that when the positioning fixture used for screw processing clamps a long screw, there is a lack of support for the middle position of the screw. Since the processing equipment will generate downward extrusion force when it comes into contact with the screw, the screw may be slightly bent, which will affect the yield of screw processing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning device for machining the screw of an electric screw press, comprising a support base, a support mechanism, and a receiving mechanism. The support mechanism is disposed on the top of the support base and includes a sliding cavity, a movable block, a fixed frame, a second threaded rod, and a hollow support block. The inner wall of the sliding cavity is slidably connected to the outer wall of the movable block. The bottom of the fixed frame extends into the sliding cavity and is fixedly connected to the top of the movable block. The top of the fixed frame is threadedly connected to the outer wall of the second threaded rod, and one end of the second threaded rod is rotatably connected to the bottom of the hollow support block. The receiving mechanism is disposed above the support base and includes a separator. Multiple sets of separators are fixedly installed on the front and rear inner walls of the hollow support block, and the separators are equidistantly distributed.

[0006] Preferably, the supporting mechanism further includes a first threaded rod, a first motor, and a limiting rod. A sliding cavity is provided inside the support base. The inner walls of both sides of the sliding cavity are rotatably connected to both ends of the first threaded rod. The first motor is fixedly installed on one side of the support base, and the output shaft of the first motor is fixedly connected to one end of the first threaded rod. A limiting rod is slidably installed on the top of the fixed frame, and one end of the limiting rod is fixedly connected to the bottom of the hollow support block. The hollow support block continuously supports the processing position of the screw, preventing the screw from bending due to pressure from the processing equipment, ensuring the yield rate of the screw processing, and making it applicable to screws of various diameters, thus improving the usability and practicality of the device.

[0007] Preferably, the receiving mechanism further includes a collection box and an auxiliary handle. The collection box is provided inside the hollow support block. The outer wall of the collection box is attached to but not connected to the inner wall of the hollow support block. An auxiliary handle is fixedly installed on one side of the collection box to collect the debris falling from the screw processing position, so as to avoid affecting the normal operation of the device and to enable the subsequent centralized cleaning of debris, reducing the workload of the staff during cleaning.

[0008] Preferably, two sets of mounting plates are fixedly installed on the top of the support base.

[0009] Preferably, a second motor is fixedly mounted on one side of the set of mounting plates, and a three-jaw chuck is rotatably mounted on the other side of the set of mounting plates. The output shaft of the second motor passes through the mounting plate and is fixedly connected to the three-jaw chuck.

[0010] Preferably, a cylinder is fixedly installed on one side of the other set of mounting plates, and a pointed positioning block is provided at the free end of the cylinder.

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

[0012] This electric screw press screw processing positioning device, through the coordinated use of a sliding cavity, a first threaded rod, a movable block, a first motor, a fixed frame, a second threaded rod, a hollow support block, and a limiting rod, uses the hollow support block to consistently support the screw at the processing position, preventing the screw from bending due to pressure from the processing equipment, thus ensuring a high yield rate for screw processing. It is applicable to screws of various diameters, improving the device's usability and practicality. The combined use of a collection box, a separator rod, and an auxiliary handle collects debris falling from the screw processing position, preventing it from affecting the normal operation of the device and enabling subsequent centralized cleaning of the debris, reducing the workload for workers.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a positioning device for machining the screw of an electric screw press, including a support base 1, a support mechanism 2, and a receiving mechanism 3. The support mechanism 2 is disposed on the top of the support base 1 and includes a sliding cavity 201, a movable block 203, a fixed frame 205, a second threaded rod 206, and a hollow support block 207. The inner wall of the sliding cavity 201 is slidably connected to the outer wall of the movable block 203. The bottom of the fixed frame 205 extends into the sliding cavity 201 and is fixedly connected to the top of the movable block 203. The top of the fixed frame 205 is threadedly connected to the outer wall of the second threaded rod 206. One end of the second threaded rod 206... The end is rotatably connected to the bottom of the hollow support block 207; the receiving mechanism 3 is set above the support base 1, and the receiving mechanism 3 includes a separator rod 302. Multiple sets of separator rods 302 are fixedly installed on the inner walls of the front and rear sides of the hollow support block 207, and the separator rods 302 are evenly distributed; two sets of mounting plates 4 are fixedly installed on the top of the support base 1; a second motor 6 is fixedly installed on one side of one set of mounting plates 4, and a three-jaw chuck 5 is rotatably installed on the other side of one set of mounting plates 4. The output shaft of the second motor 6 passes through the mounting plate 4 and is fixedly connected to the three-jaw chuck 5; a cylinder 7 is fixedly installed on one side of the other set of mounting plates 4, and a pointed positioning block 8 is provided at the free end of the cylinder 7.

[0021] Secondly, the supporting mechanism 2 also includes a first threaded rod 202, a first motor 204, and a limiting rod 208. The support base 1 has a sliding cavity 201 inside. The inner walls of both sides of the sliding cavity 201 are rotatably connected to the two ends of the first threaded rod 202, respectively. The first motor 204 is fixedly installed on one side of the support base 1. The output shaft of the first motor 204 is fixedly connected to one end of the first threaded rod 202. The limiting rod 208 is slidably installed on the top of the fixing frame 205. One end of the limiting rod 208 is fixedly connected to the bottom of the hollow support block 207. The hollow support block 207 always supports the processing position of the screw, preventing the screw from bending due to the pressure of the processing equipment, ensuring the yield rate of the screw processing, and being applicable to screws of various diameters, thus improving the usability and practicality of the device.

[0022] Furthermore, the receiving mechanism 3 also includes a collection box 301 and an auxiliary handle 303. The collection box 301 is installed inside the hollow support block 207.

[0023] Working principle: In use, one end of the screw is fixed by the three-jaw chuck 5. The cylinder 7 is turned on to push the pointed positioning block 8 to move and hold the other end of the screw. The first motor 204 is turned on to drive the first threaded rod 202 to rotate. Under the limit of the inner wall of the sliding cavity 201, the movable block 203 is driven to slide in the sliding cavity 201, which in turn drives the fixed frame 205 to move, so that the hollow support block 207 is always below the screw processing position. The second threaded rod 206 is rotated. Under the limit of the limit rod 208, the hollow support block 207 is driven to move upward, so that the top of the hollow support block 207 is in contact with the outer wall of the screw. Then the screw can be processed. The debris falling during the processing will pass through the gap between the partition rods 302 and fall into the collection box 301 for collection. After processing, the collection box 301 can be taken out and cleaned by pulling it outward by the auxiliary handle 303.
