Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to a drilling support device for metal workpieces. Background Technology

[0002] In the drilling process of metal workpieces, in order to ensure the positional accuracy of the drilling and the safety of the processing, the workpiece to be processed must first be stably positioned and clamped. A reliable support device is the basic link to ensure that the final product quality meets the design requirements.

[0003] Currently, in many processing scenarios, the fixation of metal workpieces still relies on traditional general-purpose fixtures, such as bench vises or multiple independent clamping plates and bolts. These methods usually require operators to manually make multiple adjustments. First, the workpiece is placed on the workbench, and then the clamping components located on different sides of the workpiece are adjusted and locked one by one. The centering and positioning of the workpiece is completed by visual inspection or with the help of measuring tools.

[0004] However, this traditional positioning and clamping method becomes inefficient when dealing with batch processing of workpieces of different sizes or situations requiring rapid production changeover. Operators need to spend a lot of time repeatedly adjusting multiple independent clamping mechanisms, and the centering accuracy heavily depends on the operator's experience and sense of responsibility, making it difficult to guarantee the consistency of the positioning reference between batches of products. In addition, manual operation makes it difficult to ensure that the clamping force applied to all sides of the workpiece is uniform. During the drilling process, the workpiece may be slightly displaced due to the cutting force, thus affecting the final machining accuracy.

[0005] Therefore, this utility model proposes a metal workpiece drilling support device to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of existing metal workpiece drilling support devices, such as cumbersome operation, low centering efficiency and accuracy when clamping and positioning workpieces of different sizes, and lack of integrated chip collection function, this utility model aims to provide a metal workpiece drilling support device with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a drilling support device for metal workpieces, including: a machine tool, a slide plate, a support table; and a positioning mechanism.

[0008] The slide plate is slidably mounted on the machine tool, the support platform is fixedly connected to the slide plate, and the positioning mechanism is mounted on the support platform.

[0009] Furthermore, the positioning mechanism includes two lateral clamping plates for lateral clamping and a clamping assembly for longitudinal clamping. The combination of the positioning mechanism and the support table enables rapid fixation of the workpiece, and the combination of the sliding plate and the machine tool enables the movement of the workpiece position.

[0010] Preferably, the positioning mechanism further includes a support base, a bidirectional screw, two threaded blocks, two push plates, and two force-bearing plates. The support base is fixed on the support platform. The bidirectional screw is rotatably disposed in the support base with opposite thread directions at both ends. The two threaded blocks are threaded to both ends of the bidirectional screw, and the two push plates are drivenly connected to the two threaded blocks respectively. The two force-bearing plates are connected between the push plates and the side clamping plates.

[0011] Preferably, the positioning mechanism further includes a reinforcing ring, two force-bearing plates are slidably disposed on the inner wall of the reinforcing ring, and each push plate is provided with a displacement groove, with the threaded block slidingly engaging with the displacement groove.

[0012] Preferably, the positioning mechanism further includes a positioning plate disposed on the support platform, and the rear side of the lateral clamp is provided with a groove that engages with and slides with the positioning plate.

[0013] Preferably, the clamping assembly includes an internal screw rotatably disposed on a lateral clamping plate, and a clamping block threadedly connected to the internal screw.

[0014] Preferably, the device further includes a sliding assembly, which includes a slide groove disposed on the machine tool and a pulley disposed in the slide plate and rolling in cooperation with the slide groove.

[0015] Preferably, the device further includes a detachable collection mechanism, which includes a collection box with a slide bar on it. The bottom of the slide plate is provided with a corresponding slide rail. The slide bar and the slide rail are slidably engaged. A pin passes through the insertion platform and the slide rail on the slide plate in sequence to connect with the slide bar, thereby locking the collection box.

[0016] This utility model has the following beneficial effects: 1. This utility model, by setting a bidirectional screw and using its rotation to link the push plate, force plate and side clamping plate, enables the clamping plates on both sides to move synchronously towards each other, which solves the problem in the prior art that when positioning workpieces of different sizes, it is necessary to adjust the clamps on both sides separately, which is cumbersome and has low centering efficiency. It achieves the technical effect of quickly and automatically centering and clamping the workpiece, improving positioning accuracy and ease of operation.

[0017] 2. This utility model solves the problem in the prior art that metal shavings generated during drilling are easily scattered to various parts of the machine tool, making cleaning difficult and affecting the service life of the equipment. It achieves the technical effect of centralized collection of metal shavings, keeping the machine tool clean, facilitating cleaning, and extending the service life of the equipment.

[0018] 3. This utility model solves the problem of high friction in the support device during movement, which leads to unstable and laborious movement, by setting a sliding component and providing a pulley that can roll in the machine tool slide groove inside the slide plate. It achieves the technical effect of reducing movement friction and making the pushing process of the entire device more stable, labor-saving and efficient. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this utility model without creative effort are within the scope of protection of this utility model.

[0022] Example: Please refer to Figures 1 to 4 This utility model provides a metal workpiece drilling support device, which aims to solve the problems of complex clamping and positioning structures for workpieces of different sizes and poor adaptability, as well as the inconvenience of collecting drilling debris in the prior art.

[0023] like Figure 1 and Figure 2 As shown, the metal workpiece drilling support device includes a machine tool 1, a slide plate 2 slidably mounted on the machine tool 1, a support platform 3 fixedly connected to the slide plate 2, a positioning mechanism 4 mounted on the support platform 3, and a collection mechanism 5 detachably mounted on the bottom of the slide plate 2. The machine tool 1 provides the installation foundation and motion guide for the entire device. The whole consisting of the slide plate 2 and the support platform 3 is used to carry the workpiece and realize position movement. The positioning mechanism 4 is used to complete the precise positioning and clamping of the workpiece, and the collection mechanism 5 is used to collect the metal debris generated during the drilling operation.

[0024] To solve the above-mentioned technical problems, the core of the technical solution of this embodiment lies in the internal structure of the positioning mechanism 4, and the structural cooperation and connection relationship between the positioning mechanism 4 and the support platform 3.

[0025] Please refer to the following carefully. Figure 2 and Figure 3 The core structure will be described in detail below: The positioning mechanism 4 includes a support base 405 fixedly connected to the front side of the support platform 3, and a positioning plate 401 disposed on the support platform 3. A bidirectional screw 408 is rotatably disposed within the support base 405, with the threads at both ends of the bidirectional screw 408 having opposite directions. Two threaded blocks 409 are threadedly connected to both ends of the bidirectional screw 408, respectively. Two push plates 406 are rotatably connected about the shaft in the support base 405, and are respectively connected to the two threaded blocks 409. Each push plate 406 is provided with a displacement groove 407, and the corresponding threaded block 409 slides into the displacement groove 407. Two force-bearing plates 404 are rotatably connected to the two push plates 405. Between the 6 and the two side clamping plates 402, the positioning mechanism 4 also includes a reinforcing ring 403. Two force-bearing plates 404 are slidably disposed on the inner wall of the reinforcing ring 403. The rear side of each of the two side clamping plates 402 is provided with a groove, which engages with and slides with the positioning plate 401. This linkage structure driven by the bidirectional screw 408 ensures that the two side clamping plates 402 move synchronously toward or away from each other on the support platform 3, thereby realizing the rapid centering and clamping of the workpiece. The clamping assembly 410 is disposed on the side clamping plate 402. The clamping assembly 410 includes an inner screw 4101 rotatably disposed on the side clamping plate 402 and a clamping block 4102 threadedly connected to the inner screw 4101.

[0026] Based on the above embodiments, the present invention may further include the following preferred technical solutions: To make the movement of the entire device more efficient and stable, a sliding component 411 is also included. Please refer to [reference needed]. Figure 1 and Figure 2 The sliding assembly 411 includes a slide groove 4112 disposed on the machine tool 1, and a pulley 4111 disposed in the slide plate 2 and rolling in cooperation with the slide groove 4112.

[0027] As another preferred embodiment, for timely collection of metal debris generated during drilling, please refer to... Figure 1 and Figure 4 The device also includes a collection mechanism 5 detachably installed on the bottom of the slide plate 2. The collection mechanism 5 includes a collection box 501, and its installation structure is as follows: a slide rail 503 is fixedly connected to the bottom of the slide plate 2, a slide rod 502 is provided on the collection box 501 and slides slidingly engaged with the slide rail 503, and a plug 504 is fixed on the slide plate 2. A pin 505 passes through the plug 504 and the slide rail 503 in sequence and connects with the slide rod 502, thereby locking the collection box 501.

[0028] Working principle: Before drilling, the metal workpiece needs to be fixed. The positioning mechanism 4 can clamp metal workpieces of different sizes and fix them on the support table 3. The back side of the metal workpiece to be processed is attached to the front side of the positioning plate 401. Then, the double-acting screw 408 is rotated. The double-acting screw 408 rotates on the inner wall of the support seat 405. The support seat 405 is fixed to the front side of the support table 3. When the support seat 405 rotates clockwise, because the threads on both sides are in opposite directions, the two threaded blocks 409 move closer to each other under the principle of thread transmission. Under the lateral traction of 09, the included angle between the two push plates 406 decreases, and the two push plates 406 rotate about the shaft in the support base 405. At this time, the distance between the front end of the displacement groove 407 and the threaded block 409 shortens, and the longitudinal relative displacement between the threaded block 409 and the push plate 406 is canceled out by the space of the displacement groove 407. At the same time, the distance between the rear end of the push plate 406 and the side clamping plate 402 shortens, and the rotational connection between the push plate 406 and the force plate 404 is established. When the two push plates 406 rotate towards the center, they drive the two force plates 404 to rotate towards the center. The middle side clamping plate 402 is compressed, while the force plate 404 slides on the inner wall of the reinforcing ring 403, counteracting the longitudinal relative displacement of the force plate 404. This causes the two side clamping plates 402 to move towards the center on the support platform 3. At the same time, the grooves on the rear side of the side clamping plates 402 slide on the positioning plate 401, providing a stable movement trajectory for the side clamping plates 402, until the two side clamping plates 402 are in close contact with the side of the metal workpiece to be processed. Then, the clamping assembly 410 longitudinally positions the metal workpiece to be processed, and the inner screw 4101 is rotated to drive the screw thread. In principle, the clamping block 4102 moves longitudinally along the inner wall of the lateral clamping plate 402 until the rear side of the clamping block 4102 is in close contact with the front side of the metal workpiece to be processed, thereby completing the positioning of the metal workpiece to be processed. Then, the support table 3 is pushed to the drilling position by the external drive structure to complete the drilling work. During the movement, the sliding component 411 provides a more stable sliding path for the support device. The slide plate 2 at the bottom of the support table 3 slides in the slide groove 4112 of the machine tool 1. The pulley 4111 in the slide plate 2 reduces the coefficient of friction, making the whole movement process more efficient. When drilling metal workpieces, a lot of metal chips are generated. The collection mechanism 5 is used to collect the chips in time to prevent them from falling into the gaps of the machine tool 1 and other parts, which would affect the service life of the equipment. When assembling the collection box 501, the slide plate 2 is fixed to the machine tool 1 near the front end by an external drive structure. Then, the bottom of the collection box 501 is pushed backward along the bottom of the inner wall of the machine tool 1. At this time, the two slide rods 502 on the left and right sides of the collection box 501 slide into the slide rail 503 at the bottom of the slide plate 2 in sequence until the two slide rods 502 on the rear side are connected to the inner wall of the slide rail 503. The collection box 501 is then installed in place. At this time, two pins 505 are inserted into the two inserts 504 respectively. The pins 505 pass through the two holes on the upper and lower sides of the inserts 504 and the slide rail 503 in sequence, and are connected to the front slide rods 502, thereby fixing the collection box 501 to the bottom of the slide plate 2. After the drilling work is completed, the metal chips are swept forward into the collection box 501 with a brush.
