Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, and in particular to a multifunctional quick positioning pressure plate for a drilling machine worktable. Background Technology

[0002] In machining processes, a drilling machine is a fundamental piece of equipment used to drill holes in workpieces. To ensure drilling accuracy and operational safety, the workpiece to be processed must be stably and reliably fixed on the drilling machine's worktable. Currently, the most common way to achieve this is by manually clamping the workpiece using a bench vise or various clamping plates and fixtures.

[0003] When using these traditional clamping devices, operators typically need to go through a tedious manual alignment process. Specifically, the operator must first roughly place the workpiece on the fixture, and then repeatedly fine-tune the workpiece's position by visual inspection or with the aid of scribing tools, aligning the predetermined drilling center point with the central axis of the drilling machine spindle. This process not only consumes a lot of time and reduces production efficiency, but the final positioning accuracy also largely depends on the operator's experience and sense of responsibility, making it difficult to guarantee consistency in batch processing.

[0004] Furthermore, during alignment and locking, the clamping force is entirely controlled manually by feel. For workpieces requiring high surface finish or made of soft materials, excessive clamping force can easily cause indentations, scratches, or even deformation, affecting product quality. Conversely, insufficient clamping force may cause the workpiece to shift or vibrate under drilling forces, damaging both the workpiece and the cutting tool, and posing safety hazards. Current technology lacks an integrated solution that simultaneously achieves rapid and accurate positioning with adaptive clamping force adjustment.

[0005] Therefore, this utility model proposes a multi-functional quick positioning pressure plate for a drilling machine worktable to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a multi-functional quick positioning pressure plate for a drilling machine worktable, which aims to improve the problems of low efficiency, low accuracy and easy damage to the workpiece surface caused by rigid clamping in the prior art.

Each positioning component includes a slide rail, a sliding block, a positioning block and a connecting arm. The multi-functional quick positioning pressure plate for the drilling machine worktable also includes two protective components.

The slider is slidably accommodated in the inner cavity opened at the front end of the positioning block. The limiting plate is slidably disposed on the side of the slider away from the workpiece. The two ends of the spring elastically abut against the bottom wall of the limiting plate and the inner cavity of the positioning block, respectively, realizing automated centering positioning and elastically buffered clamping.

[0008] Preferably, the transmission mechanism includes a rotating column, a rotating rod, and two connecting rods. The output shaft of the motor is connected to the rotating column for transmission. The rotating column and the rotating rod are coaxially fixedly connected. One end of each of the two connecting rods is symmetrically rotatably connected to the two radial ends of the rotating rod, and the other end is rotatably connected to the corresponding sliding block.

[0009] Preferably, the protective component further includes an anti-slip strip, which is embedded in the surface of the slider facing the material to be processed.

[0010] Preferably, the inner cavity opening of the positioning block is provided with an inwardly protruding limiting edge, and the outer contour dimension of the limiting plate is larger than the channel opening formed by the limiting edge, so as to prevent the limiting plate from coming out of the positioning block.

[0011] Preferably, the connection between the connecting arm and the sliding block is a rotatable connection, and the connection between the connecting arm and the positioning block is also a rotatable connection.

[0012] Preferably, the multi-functional quick positioning pressure plate for the drilling machine worktable further includes a fixed pressure plate, which is threaded onto the drilling machine body, and the axis of the fixed pressure plate is perpendicular to the moving direction of the two positioning blocks.

[0013] Preferably, the rotating column and the rotating rod are connected by a key.

[0014] Preferably, the inner wall of the sliding block is provided with a groove that matches the shape of the slide rail to achieve a stable sliding fit.

[0015] This utility model has the following beneficial effects: 1.

[0016] 2. This utility model solves the problem in the prior art that rigid clamping force is difficult to control and the workpiece surface is easily damaged due to excessive clamping force by setting a protective component consisting of a slider, spring and limiting plate inside the positioning block.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figures 1-5The present invention provides an embodiment of a multi-functional quick positioning pressure plate for a drilling machine worktable, comprising a drilling machine body 1, a motor 201 fixedly mounted on the drilling machine body 1, and positioning components 2 symmetrically arranged on the drilling machine body 1. The motor 201 synchronously drives the positioning components 2 through a transmission mechanism to achieve opposite or opposite movement. The positioning components 2 have the same structure. Each positioning component 2 includes a slide rail 206 fixed on the drilling machine body 1, a sliding block 205 slidably connected to the slide rail 206, a positioning block 208, and a connecting arm 207. One end of the connecting arm 207 is connected to the sliding block 205, and the other end is connected to the positioning block 208. The transmission mechanism includes a rotating column 202, a rotating rod 203, and two connecting rods 204. The output shaft of the motor 201 is connected to the rotating column 202. The rotating column 202 and the rotating rod 203 are coaxially fixedly connected. The specific method of this coaxial fixed connection is either integral molding or key connection. One end of each of the two connecting rods 204 is symmetrically rotatably connected to the two radial ends of the rotating rod 203. The other end of each of the two connecting rods 204 is rotatably connected to the corresponding sliding block 205, thereby converting the rotational motion of the rotating rod 203 into synchronous linear motion of the two sliding blocks 205 on their respective slide rails 206. Each positioning block 208 is provided with a protective component 3, which includes a slider 301, a limiting plate 303 and a spring 304. The slider 301 is slidably accommodated in the inner cavity opened at the front end of the positioning block 208. The limiting plate 303 is slidably disposed on the side of the slider 301 away from the workpiece. The spring 304 is a compression spring. The two ends of the spring 304 elastically abut against the limiting plate 303 and the bottom wall of the inner cavity of the positioning block 208, respectively. The elastic deformation of the spring 304 provides clamping and buffering. In the cooperation structure between the protective component 3 and the positioning block 208, the front end of the positioning block 208 has an inner cavity in which the slider 301 is slidably accommodated. The surface of the slider 301 facing the material to be processed is inlaid with an anti-slip strip 302, which is used to increase the friction force in contact with the workpiece. On the side of the slider 301 away from the workpiece, a limiting plate 303 is slidably provided. In order to prevent the limiting plate 303 and the slider 301 from coming out of the inner cavity of the positioning block 208, the opening of the inner cavity of the positioning block 208 is provided with an inwardly protruding limiting edge. The outer contour dimension of the limiting plate 303 is larger than the channel opening formed by the limiting edge, thereby forming an anti-drop structure. The spring 304 is provided between the limiting plate 303 and the bottom wall of the inner cavity of the positioning block 208. When the clamping force is too large, the slider 301 is pressed inward and slides and compresses the spring 304 to achieve pressure buffering. In the guiding and mating structure between the positioning component 2 and the drilling machine body 1, the slide rail 206 is firmly fixed on the drilling machine body 1, and the inner wall of the sliding block 205 is provided with a groove that matches the shape of the slide rail 206. In the assembled state, the sliding block 205 slides on the slide rail 206 through the groove, ensuring the high stability and precise guidance of the sliding block 205 during reciprocating motion. The multi-functional quick positioning pressure plate used for the drilling machine worktable also includes a fixed pressure plate 4. The fixed pressure plate 4 is threaded onto the drilling machine body 1, and the axis of the fixed pressure plate 4 is perpendicular to the moving direction of the two positioning blocks 208, which is used to apply the final locking force to the workpiece that has been initially centered by the positioning component 2. The connecting arm 207 and the sliding block 205 are connected by a rotatable connection, and the connecting arm 207 and the positioning block 208 are also connected by a rotatable connection. This rotatable connection ensures the flexibility of the mechanism during transmission. The coaxial fixed connection between the rotating column 202 and the rotating rod 203 is specifically a key connection. The surface of the slider 301 of the protective component 3 is inlaid with anti-slip strips 302. The inner opening of the positioning block 208 is machined with an inwardly protruding limiting edge. The inner diameter of the limiting edge is smaller than the outer contour size of the limiting plate 303, so as to reliably limit the axial movement of the limiting plate 303. Specifically, the inner wall of the sliding block 205 is provided with a groove that matches the shape of the slide rail 206. Through the cooperation of the groove and the slide rail 206, the sliding block 205 can slide stably. The multi-functional quick positioning pressure plate used in the drilling machine worktable also includes a fixed pressure plate 4. The fixed pressure plate 4 is threaded onto the drilling machine body 1, and the axis of the fixed pressure plate 4 is perpendicular to the moving direction of the two positioning blocks 208.

[0021] Working principle: When it is necessary to center and position the material, the motor 201 is started. The output shaft of the motor 201 drives the rotating column 202 to rotate. Since the rotating column 202 and the rotating rod 203 are coaxially fixedly connected, the rotating rod 203 rotates synchronously. The rotating rod 203 pushes the two sliding blocks 205 to slide synchronously along their respective fixed slide rails 206 through the two connecting rods 204. The movement of the sliding blocks 205 is transmitted to the positioning blocks 208 through the connecting arm 207, driving the two positioning blocks 208 to move synchronously towards the center or open to both sides. Due to the symmetrical layout of the entire transmission mechanism, the displacement of the two positioning blocks 208 is always equal, thereby realizing automatic centering and clamping or releasing of materials of different sizes. During the clamping process, the anti-slip strip 302 and slider 301 of the protective component 3 first come into contact with the material surface. When the clamping force is too large, the material surface squeezes the slider 301, causing the slider 301 to slide inward in the inner cavity opened at the front end of the positioning block 208. The sliding of the slider 301 will drive the limiting plate 303 to move and compress the spring 304. The compression deformation of the spring 304 absorbs the excess pressure and plays a buffering and protective role for the material surface. After the processing is completed, when the positioning block 208 resets outward, the elastic force of the spring 304 pushes the limiting plate 303 to reset. The limiting plate 303 then drives the slider 301 and anti-slip strip 302 to reset, preparing for the next clamping. After the material is centered and positioned, the fixed pressure plate 4 can be operated. The fixed pressure plate 4 moves on the drilling machine body 1 through the thread, and its end extends to press against the material, providing the final stable locking.
