Description

Technical Field

[0001] This utility model relates to a workpiece clamping device, and more particularly to a workpiece clamping device that can be assembled and used, reduces usage costs, and improves practicality. Background Technology

[0002] When workpieces such as wood are joined together with glue or adhesive, or when two workpieces need to be fixed together during the joining process, in order to ensure that the two workpieces are in a mutually perpendicular structural shape so that they can be assembled into a rectangular or square frame later, clamping blocks and fixtures are used on the inner or outer sides of the two workpieces to press them tightly together during the frame joining process to prevent relative displacement between the two workpieces. This ensures that the two workpieces can be joined in an accurate position.

[0003] However, the most common joining methods for existing workpieces include a flat joint where two workpieces are joined by their straight end faces abutting each other, and a beveled joint where two workpieces are joined by their angled end faces abutting each other. The flat joint uses an L-shaped right-angle clamping block with two clamps, abutting against the outer or inner surfaces of the two workpieces to maintain their right angle. The beveled joint, on the other hand, requires two separate clamping blocks abutting against the outer surfaces of the two workpieces, followed by three clamps, to achieve the desired right angle. The angular clamping force is converted into a clamping force in the oblique direction to achieve a precise and fixed joint effect. It can be seen that, when using existing workpieces, different types of clamping blocks need to be purchased and used with fixtures depending on the joint method. This not only increases the cost of use but also relatively limits the practicality of existing clamping blocks. In view of this, since existing L-shaped right-angle clamping blocks or separate clamping blocks have the above-mentioned problems and shortcomings, there is room for improvement in existing L-shaped right-angle clamping blocks or separate clamping blocks. Utility Model Content

[0004] Therefore, to address the issue that existing L-shaped right-angle clamping blocks or separate clamping blocks cannot be used simultaneously for both flat and oblique joints, which not only limits and reduces their practicality but also requires the purchase of different types of clamping blocks, increasing inconvenience and cost, this invention provides a workpiece clamping device that can be used for both flat and oblique joints. This device is relatively convenient to use and improves practicality, eliminating the need to purchase different types of clamping blocks, significantly reducing usage costs. Furthermore, it can be assembled with frames of different sizes, thus providing a workpiece clamping device that can be assembled and used, reduces usage costs, and improves practicality.

[0005] Based on the above objectives, this utility model provides a workpiece clamping device, characterized in that the workpiece clamping device is provided with two clamping blocks, the two clamping blocks can be detachably set, or can be combined to form an L-shaped right-angle clamping device, used in conjunction with a fixture to fix the workpiece, each of the clamping blocks is provided with two parallel abutting surfaces, and the two abutting surfaces are connected by two inclined side surfaces, each of the clamping blocks is provided with a locking part on each of the inclined side surfaces, the locking parts on the two inclined side surfaces are in a structure of matching shape, so that the two clamping blocks can be combined by the two locking parts to be vertically set.

[0006] Furthermore, in the workpiece clamping device described above, the engaging portion on one inclined side of each clamping block is a recess, while the engaging portion on the other inclined side of each clamping block is a protrusion, and the shape and contour of the protrusion and the recess can match.

[0007] Furthermore, in the workpiece clamping device described above, one of the engaging portions of each clamping block is a polygonal recess with a gradually expanding opening, and the other engaging portion of each clamping block is a polygonal tapering protrusion. When the two clamping blocks are combined, a stable engaging effect can be provided by combining the gradually expanding polygonal recess with the tapering polygonal recess.

[0008] Preferably, in the workpiece clamping device as described above, each clamping block has a clamping portion on one of the abutting surfaces between the two engaging portions, and the clamping portion has two intersecting clamping surfaces. When the two clamping blocks are arranged perpendicularly, one clamping surface of one clamping block is arranged parallel to one clamping surface of the other clamping block.

[0009] Preferably, in the workpiece clamping device described above, each of the clamping blocks is provided with at least one clamping hole for clamping by a clamp.

[0010] Preferably, in the workpiece clamping device described above, each of the clamping blocks is provided with two spaced-apart clamping holes.

[0011] Preferably, in the workpiece clamping device described above, each of the clamping blocks has a plurality of spaced grooves on each of the abutting surfaces, thereby increasing the friction between each of the abutting surfaces and a workpiece.

[0012] By employing the aforementioned technical means, when in use, the two clamping blocks of this utility model can be joined or separated through corresponding engaging parts. This allows the workpiece clamping device of this utility model to be applied to both flat and oblique joint workpieces, enabling users to conveniently and flexibly configure and use it according to the type of workpiece to be joined. This significantly improves the practicality of the workpiece clamping device of this utility model, eliminating the need to purchase different types of clamping blocks simultaneously. This increases the convenience of use and reduces the cost required for use, thereby providing a workpiece clamping device that can be assembled and used, reduces usage costs, and improves practicality.

[0023] The following, in conjunction with the accompanying drawings and preferred embodiments of the present invention, further illustrates the technical means adopted by the present invention to achieve its intended purpose.

[0024] This utility model provides a workpiece clamping device. Please refer to the following: Figures 1 to 4 As shown, the workpiece clamping device has two clamping blocks 10, which are detachably connected and have the same structure. Each clamping block 10 is slightly trapezoidal and has two parallel abutment surfaces 11 and 12, which are connected by two inclined side surfaces 13. Each clamping block 10 has a locking part 14 and 15 on each inclined side surface 13. The locking parts 14 and 15 on the two inclined side surfaces 13 have a matching shape structure. For example, the locking part 14 on one inclined side surface 13 is a concave part, while the locking part 15 on the other inclined side surface 13 is a convex part. The shape and contour of the convex part and the concave part can match, so that the two clamping blocks 10 can be connected by the two locking parts 14 and 15 and are arranged vertically. Further, please refer to the following: Figure 4 and Figure 5 As shown, one of the engaging portions 14 of each clamping block 10 is a polygonal recess with a gradually expanding opening 141, and the other engaging portion 15 of each clamping block 10 is a polygonal tapering protrusion. This allows for a stable engagement effect when the two clamping blocks 10 are combined, through the combination of the gradually expanding and tapering polygonal recesses. Furthermore, each clamping block 10 has a clamping portion 16 on one of the contact surfaces 11 between the two engaging portions 14 and 15. The clamping portion 16 has two intersecting clamping surfaces 161. When the two clamping blocks 10 are engaged as follows... Figure 1 The combination shown or as Figure 8 When arranged vertically as shown, one clamping surface 161 of one clamping block 10 is parallel to one clamping surface 161 of another clamping block 10. Preferably, each clamping block 10 is provided with at least one clamping hole 17 for clamping by a clamp. Preferably, each clamping block 10 is provided with two spaced clamping holes 17. Preferably, each clamping block 10 is provided with several spaced grooves 18 on each of the contact surfaces 11, 12 to increase the friction between each of the contact surfaces 11, 12 and a workpiece.

[0025] Please refer to the following: Figure 6As shown, when the workpiece clamping device of this utility model is used for two workpieces 20 joined together in a flat manner, firstly, after the two clamping blocks 10 are combined, the two workpieces 20 are placed on the outside of the two clamping blocks 10, and the two clamps 30 are respectively engaged with one of the clamp holes 17 of the two clamping blocks 10, and simultaneously abut against the two workpieces 20. This allows for convenient and quick clamping of the two workpieces 20 between the two clamping blocks 10 and the two clamps 30. Since the two clamping blocks 10 are vertically arranged via the relatively engaging engaging parts 14 and 15, clamping the two workpieces 20 between the two clamping blocks 10 and the two clamps 30 ensures that the two workpieces 20 are stably and vertically joined. Further, please refer to... Figure 7 As shown, when the workpiece clamping device of this utility model is used for two workpieces 20 that are joined together, the two clamping blocks 10 can be combined, and the two workpieces 20 can be placed inside the two clamping blocks 10. The two clamps 40 can be used to abut against the two clamping blocks 10 and the two workpieces 20 respectively, so that the two workpieces 20 can be clamped between the two clamping blocks 10 and the two clamps 40, ensuring that the two workpieces 20 are joined firmly and vertically.

[0026] Please refer to the following: Figure 8 and Figure 9 As shown, when the workpiece clamping device of this utility model is used for two workpieces 50 joined at an oblique angle, firstly, after separating the two clamping blocks 10, the clamping blocks 10 are respectively placed against the outer sides of the two workpieces 50, with the clamping portion 16 of each clamping block 10 facing outwards. Three clamps 60 and 70 are prepared, of which two clamps 60 and 70 are respectively abutted against the two clamping blocks 10 and the two workpieces 50, and the remaining clamp 60 and 70 abut against one of the clamping surfaces 161 of the clamping portion 16 of the two clamping blocks 10. Since the corresponding clamping surfaces 161 of the two clamping blocks 10 are arranged in parallel, the clamps 60 and 70 can be stably set between the two clamping blocks 10, so that the two workpieces 50 can be stably and vertically joined by the two clamping blocks 10 and the three clamps 60 and 70.

[0027] Please refer to the following: Figure 10 Another embodiment of the workpiece clamping device of this utility model is shown, which is similar to... Figure 1 The difference in the embodiments is that each clamping block 10 is provided with a clamping part 16 on each abutting surface 11, 12 between the two engaging parts 14, 15, so that each clamping block 10 has two clamping parts 16.

[0028] By means of the above-mentioned technical means, when the workpiece clamping device of this utility model is in use, the two clamping blocks 10 can be joined or separated by corresponding engaging parts 14 and 15, so that the workpiece clamping device of this utility model can be used on workpieces 20 and 50 with flat joint and oblique joint at the same time. This allows users to conveniently configure and use the device according to the type of workpieces 20 and 50 to be joined, greatly improving the practicality of the workpiece clamping device of this utility model. It eliminates the need to purchase different types of clamping blocks 10 for use, thereby increasing the convenience of use and reducing the cost required for use. This provides a workpiece clamping device that can be assembled and used, reduces the cost of use, and improves practicality.
