Description

Technical Field

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

[0002] In the field of machining, workpiece drilling is a common and critical process, and its machining accuracy and efficiency directly affect the final quality of the product and the production cost.

[0003] Currently, traditional workpiece drilling methods rely heavily on the operator's experience and manual operation to position the workpiece. The operator needs to determine the drilling position with the naked eye and simple measuring tools, and then place the workpiece on the drilling machine table to drill.

[0004] The aforementioned existing technical solutions have the following drawbacks: the accuracy of manual positioning is difficult to guarantee, and there may be significant differences in positioning between different operators and between the same operator at different times. This can lead to inaccurate drilling positions. In addition, manual positioning is inefficient, which can significantly increase the production cycle and reduce production efficiency in mass production, making it difficult to meet the needs of modern large-scale production. Utility Model Content

[0005] The purpose of this invention is to provide a positioning device for drilling workpieces to solve the problems existing in the prior art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A workpiece drilling positioning device includes a base plate. A limiting unit is fixedly installed on the top of the base plate, and a positioning unit is slidably installed within the limiting unit. The positioning unit includes a base plate, a first vertical plate on the left side of the base plate, a second vertical plate on the right side of the base plate, a horizontal plate extending to the left from the top of the second vertical plate, a gap between the left side of the horizontal plate and the right side of the first vertical plate, a through-hole at the top of the horizontal plate, a fixed plate connecting the rear ends of the first and second vertical plates to the same side, a forward-extending edge extending from the bottom of the fixed plate, a gap between the bottom of the edge and the top of the base plate, and a locking unit in the middle of the first vertical plate for locking the workpiece between the first and second vertical plates.

[0008] By adopting the above technical solution, the workpiece to be drilled is placed inside the first and second vertical plates. The edge can support the workpiece. Then, the workpiece to be drilled is pressed against the first and second vertical plates by the locking unit. Since the positioning unit is slidably installed in the limiting unit, the limiting unit can play both a guiding and limiting role. Therefore, the positioning unit can be slid along the limiting unit to be directly below the drill bit of the electric drill. The operator then presses the electric drill, so that the drill bit passes through the round hole to drill the workpiece. This achieves the purpose of high efficiency, easy operation, and low cost of this device.

[0009] In a further embodiment, the locking unit includes a clamping plate, a screw, and a handle. A threaded hole is provided at the center of the middle section of the first vertical plate, and the screw is screwed into the threaded hole. The right end of the screw passes through and extends to the outside of the threaded hole, and the clamping plate is fixedly installed on the right end of the screw.

[0010] By adopting the above technical solution, when the clamping plate needs to clamp the workpiece, the operator rotates the handle to make the screw drive the clamping plate to rotate towards the side closer to the workpiece. Conversely, when the clamping plate no longer needs to clamp the workpiece, the operator rotates the handle in the opposite direction to make the screw drive the clamping plate to rotate away from the workpiece, thereby achieving the clamping and releasing of the workpiece.

[0011] In a further embodiment, the limiting unit includes a first guide plate and a second guide plate, the first guide plate and the second guide plate are arranged in parallel, the first guide plate is spaced apart on the rear side of the second guide plate, the rear side of the positioning unit is attached to the front side of the first guide plate, and the front side of the positioning unit is attached to the rear side of the second guide plate.

[0012] By adopting the above technical solution, the first guide plate and the second guide plate limit the front and rear directions of the positioning device, thereby not affecting the drilling quality of the workpiece and improving the drilling efficiency of the device.

[0013] In a further embodiment, forward-facing cylinders are fixedly installed at both ends of the front side of the fixing plate, and the length of the cylinders is shorter than the front and rear width of the extension edge.

[0014] By adopting the above technical solution, when the operator puts the workpiece to be drilled into the first vertical plate and the second vertical plate, the side of the workpiece close to the cylinder needs to be in contact with the two cylindrical surfaces to limit the workpiece. Also, because the workpiece will generate heat during the drilling process, the contact area between the cylinder and the workpiece is relatively small, which facilitates heat dissipation of the workpiece.

[0015] In a further embodiment, the rear side of the horizontal plate and the rear side of the second vertical plate are coplanar, and the front-to-back width of the horizontal plate is smaller than the front-to-back width of the second vertical plate.

[0016] By adopting the above technical solution, it is convenient for operators to place the workpiece to be drilled into the first vertical plate and the second vertical plate.

[0017] In a further embodiment, the bottom left end of the first guide plate is provided with a through hole running from front to back.

[0018] By adopting the above technical solution, when the drill bit drills a hole in the workpiece, the workpiece will generate heat. Therefore, water is usually poured into the workpiece from top to bottom, and the water flow through the hole facilitates the discharge from the first guide plate and the second guide plate.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. The spacing between the bottom surface of the edge and the top surface of the base plate prevents the drill bit from moving too downwards during drilling and damaging the base plate, thus protecting the base plate.

[0021] 2. The horizontal plate has a spacing on the left side and the first vertical plate on the right side. Since the workpiece of this device is L-shaped, the spacing provides a space for the top of the workpiece, which can achieve the effect of the workpiece being able to completely enter the positioning unit.

[0028] Example 1:

[0029] like Figures 1-3 As shown, a workpiece drilling positioning device includes a base plate 1. A limiting unit 2 is fixedly installed on the top of the base plate 1. A positioning unit 3 is slidably installed inside the limiting unit 2. The positioning unit 3 includes a base plate 31. A first vertical plate 32 is provided on the left side of the base plate 31, and a second vertical plate 33 is provided on the right side of the base plate 31. A horizontal plate 34 extends to the left from the top of the second vertical plate 33. A gap is provided between the left side of the horizontal plate 34 and the right side of the first vertical plate 32. A through-hole is provided at the top of the horizontal plate 34. The same fixing plate 37 is connected to the side of the rear ends of the first vertical plate 32 and the second vertical plate 33 that are close to each other. A forward-extending edge 35 extends from the bottom end of the fixing plate 37. A gap is provided between the bottom of the edge 35 and the top of the base plate 31. A locking unit 4 is provided in the middle of the first vertical plate 32. The locking unit 4 is used to lock the workpiece 5 between the first vertical plate 32 and the second vertical plate 33.

[0030] The locking unit 4 includes a clamping plate 41, a screw 42, and a handle 43. A threaded hole is provided at the center of the middle section of the first vertical plate 32, and the screw 42 is screwed into the threaded hole. The right end of the screw 42 passes through and extends to the outside of the threaded hole. The clamping plate 41 is fixedly installed on the right end of the screw 42. The limiting unit 2 includes a first guide plate 21 and a second guide plate 22. The first guide plate 21 and the second guide plate 22 are arranged in parallel. The first guide plate 21 is spaced apart on the rear side of the second guide plate 22. The rear side of the positioning unit 3 is attached to the front side of the first guide plate 21, and the front side of the positioning unit 3 is attached to the rear side of the second guide plate 22. Both ends of the front side of the fixing plate 37 are fixedly installed with forward-facing cylinders 36. The length of the cylinders 36 is shorter than the front-rear width of the extension edge 35. The rear side of the horizontal plate 34 and the rear side of the second vertical plate 33 are coplanar. The front-rear width of the horizontal plate 34 is smaller than the front-rear width of the second vertical plate 33. A through hole is provided at the bottom left end of the first guide plate 21.

[0031] Specific implementation process: First, the operator places the workpiece to be drilled between the first vertical plate 32 and the second vertical plate 33 of the positioning unit 3. During placement, the workpiece should be close to the cylinders 36 at both ends of the front side of the fixing plate 37, with one side of the workpiece fitting against the front of the two cylinders 36. This provides initial positioning of the workpiece. Simultaneously, the forward-facing extension 35 at the bottom of the fixing plate 37 provides support for the workpiece, ensuring stable placement. Next, the operator rotates the handle 43. Since the screw 42 is screwed into the threaded hole in the middle section of the first vertical plate 32, and the clamping plate 41 is fixedly installed at the right end of the screw 42, as the handle 43 rotates, the screw 42 drives the clamping plate 41 to move towards the side closer to the workpiece until the clamping plate 41 firmly clamps the workpiece between the first vertical plate 32 and the second vertical plate 33, completing the workpiece fixation. Then, due to the sliding installation of the positioning unit 3... Between the first guide plate 21 and the second guide plate 11 of the limiting unit 2, the operator can push the positioning unit 3 along the limiting unit 2 to slide the positioning unit 3 directly under the drill bit. During this process, the first guide plate 21 and the second guide plate 22 limit the front and rear directions of the positioning unit 3 to ensure the stability of the movement of the positioning unit 33 and avoid affecting the drilling quality due to shaking. After positioning is completed, the operator presses the electric drill to make the drill bit move downward and pass through the round hole at the top of the horizontal plate 34 to drill the workpiece. If water cooling is used, the through hole at the bottom left of the first guide plate 21 can facilitate the water flow from the first guide plate 21 and the second guide plate 22 to drain. After drilling is completed, the handle 43 is rotated in the opposite direction to make the clamping plate 41 move away from the workpiece, and the processed workpiece can be taken out. The whole drilling process is efficient and convenient and can meet the production needs.
