Description

Technical Field

[0001] This utility model relates to the field of mechanical and electrical equipment manufacturing technology, specifically a clamping device for manufacturing mechanical and electrical equipment. Background Technology

[0002] Mechanical and electrical equipment refers to devices that integrate mechanical and electrical systems. They are capable of performing specific mechanical actions and are controlled and driven by electrical systems. These devices play a vital role in modern industrial production and daily life. Clamping devices are required to secure the electromechanical equipment during manufacturing.

[0003] Chinese patent CN218284600U discloses a clamping device for manufacturing mechanical and electrical equipment. The clamping device drives a threaded column to move downward by starting a servo motor, which causes trapezoidal block one to move inward simultaneously with trapezoidal block two. Trapezoidal block two then moves the clamping plate inward simultaneously. When the clamping plate comes into contact with the workpiece, the workpiece can be clamped securely.

[0004] The aforementioned patent has two drawbacks. Firstly, the short movement distance of the two clamping plates limits the clamping range of the workpiece. Secondly, it can only perform clamping functions and cannot position the workpiece during clamping, which can easily reduce the machining accuracy of the workpiece. Furthermore, it cannot clamp and fix triangular workpieces, resulting in low applicability. Utility Model Content

[0005] The purpose of this utility model is to provide a clamping device for manufacturing mechanical and electrical equipment, which effectively solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] A clamping device for manufacturing mechanical and electrical equipment includes a worktable. A first mounting groove is formed on the surface of the worktable. A first screw with a pair of reverse threads is rotatably mounted inside the first mounting groove. A first nut seat is mounted on each of the two reverse threads of the first screw. Two parallel limiting rods are installed inside the first mounting groove, and the first nut seats are slidably mounted on the two limiting rods. A clamping block is mounted on the upper surface of the first nut seat via an angle adjustment mechanism. A second mounting groove is formed on the upper surface of the worktable, and the length direction of the second mounting groove is perpendicular to the length direction of the first mounting groove. A second screw is rotatably mounted inside the second mounting groove, and a second nut seat is mounted on the outer surface of the second screw. A positioning block is mounted on the outer surface of the second nut seat.

[0008] Therefore, by rotating the second screw to adjust the position of the positioning block, it positions one side of the workpiece. Then, the two clamping blocks clamp the other two sides of the workpiece, achieving three-sided positioning and ensuring the accuracy of workpiece processing. Furthermore, by adjusting the angle of the clamping blocks through the angle adjustment mechanism, it clamps the two hypotenuses of the triangular workpiece, and together with the positioning block, positions the other side of the triangular workpiece. This allows for the clamping and fixing of triangular workpieces, further expanding its applicability.

[0009] Furthermore, the angle adjustment mechanism includes a guide rod connected to the upper surface of the first nut seat. The end of the guide rod extends vertically through to the upper side of the clamping block and is fitted with a top block. A telescopic rod is mounted on the upper surface of the top block. An installation block is mounted on the end of the telescopic rod. Multiple insertion rods are connected coaxially and at equal angles on the lower surface of the installation block. Multiple insertion holes are opened coaxially and at equal angles on the upper surface of the clamping block, and the insertion rods match the insertion holes.

[0010] Furthermore, a spring is fitted onto the outer surface of the telescopic rod, with both ends of the spring connected to the top block and the mounting block, respectively.

[0011] Furthermore, the top block has multiple through holes coaxially and at equal angles inside, and the end of the insertion rod passes through the through holes and is inserted into the insertion hole.

[0012] Furthermore, the outer surface of the worktable is provided with scale lines along the length of the second mounting groove.

[0013] Furthermore, the ends of both the first and second screws extend to the outside of the worktable and are equipped with turntables, with handles mounted on the outer surface of the turntables.

[0014] Furthermore, both the first and second mounting slots extend to the lower surface of the worktable.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0016] 1. This utility model, by setting the reverse thread on the first screw, enables the two clamping blocks to move in opposite directions simultaneously when the first screw is rotated, thereby achieving the purpose of clamping the workpiece. Moreover, the moving distance of the clamping blocks is longer, making it suitable for clamping workpieces in a wider range of sizes and with a wide range of applications.

[0017] 2. This utility model can position one side of the workpiece by setting a positioning block, and then clamp the other two sides of the workpiece by two clamping blocks, thereby achieving the purpose of three-sided positioning, ensuring the accuracy of workpiece processing, and the position of the positioning block can be adjusted by rotating the second screw, thus improving the applicability.

[0018] 3. By setting up an angle adjustment mechanism, the angle of the clamping block can be adjusted, and the positioning block can be used to position one side of the triangular workpiece, thereby enabling the triangular workpiece to be clamped and fixed, further improving the scope of application.

Detailed Implementation

[0024] 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.

[0025] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0026] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0027] Please see Figures 1-4 This utility model provides a clamping device for manufacturing mechanical and electrical equipment, including a worktable 100. A first mounting groove 101 is formed on the surface of the worktable 100. A first screw 102 with a pair of reverse threads is rotatably mounted inside the first mounting groove 101. A first nut seat 103 is mounted on each of the two reverse threads of the first screw 102. Two parallel limiting rods 104 are installed inside the first mounting groove 101, and the first nut seat 103 is slidably mounted on the two limiting rods 104. A clamping block 105 is mounted on the upper surface of the first nut seat 103 via an angle adjustment mechanism 200. A second mounting groove 106 is formed on the upper surface of the worktable 100, and the length direction of the second mounting groove 106 is perpendicular to the length direction of the first mounting groove 101. A second screw 107 is rotatably mounted inside the second mounting groove 106. A second nut seat 108 is mounted on the outer surface of the second screw 107, and a positioning block 109 is mounted on the outer surface of the second nut seat 108.

[0028] When in use, first rotate the second screw 107 according to the processing requirements and the size of the workpiece. Since the inner wall of the second mounting groove 106 plays a limiting role on the second nut seat 108, the second nut seat 108 can be moved along the length direction of the second screw 107 under the drive of the screw connection, and the positioning block 109 can be adjusted to a suitable position.

[0029] Next, the workpiece is placed between the two clamping blocks 105, and one side of the workpiece is abutted against the positioning block 109. At this time, the first screw 102 is rotated. Since the limiting rod 104 plays a limiting role on the first nut seat 103, the first nut seat 103 drives the two clamping blocks 105 to move closer to each other and abut against the other two sides of the workpiece under the drive of the reverse thread, thereby achieving the purpose of clamping and positioning and improving the machining accuracy.

[0030] Once the machining is complete, simply rotate the first screw 102 in the opposite direction to separate the clamping block 105 from the workpiece surface, and the workpiece can be removed.

[0031] When it is necessary to clamp a triangular workpiece, the angle of the clamping block 105 is adjusted by the angle adjustment mechanism 200 so that it clamps the two hypotenuses of the triangular workpiece. The positioning block 109 is used to position the other side of the triangular workpiece, thereby enabling the triangular workpiece to be clamped and fixed for use, which further improves the applicability.

[0032] Preferably, the angle adjustment mechanism 200 includes a guide rod 201 connected to the upper surface of the first nut seat 103. The end of the guide rod 201 extends vertically through to the upper side of the clamping block 105 and is fitted with a top block 202. A telescopic rod 206 is mounted on the upper surface of the top block 202. An installation block 203 is mounted on the end of the telescopic rod 206. A plurality of insert rods 205 are connected coaxially and at equal angles on the lower surface of the installation block 203. A plurality of insertion holes 204 are opened coaxially and at equal angles on the upper surface of the clamping block 105, and the insert rods 205 match the insertion holes 204.

[0033] When it is necessary to adjust the angle of the clamping block 105, the mounting block 203 can be pulled up to drive the insertion rod 205 out of the insertion hole 204. At this time, the clamping block 105 is released from fixation and can be rotated on the outer surface of the guide rod 201. After rotating to a suitable angle, the insertion rod 205 can be reinserted into the insertion hole 204 to achieve the purpose of adjusting and fixing the angle of the clamping block 105.

[0034] Preferably, a spring 300 is fitted on the outer surface of the telescopic rod 206, and the two ends of the spring 300 are respectively connected to the top block 202 and the mounting block 203.

[0035] By setting the spring 300, a downward pulling force can be applied to the mounting block 203 to ensure that the insertion rod 205 can be stably inserted into the insertion hole 204, avoiding the situation where the insertion rod 205 is dislodged from the insertion hole 204 and the workpiece loses its fixation due to vibration during the processing of the workpiece. In addition, the telescopic rod 206 also provides a limiting and guiding function for the spring 300, preventing it from being overstretched or bent.

[0036] Preferably, the top block 202 has multiple through holes 400 coaxially and at equal angles inside, and the end of the insertion rod 205 passes through the through holes 400 and is inserted into the insertion hole 204.

[0037] The through hole 400 provides a limiting function for the insertion rod 205, thereby improving its torsional resistance.

[0038] Preferably, the outer surface of the workbench 100 is provided with scale lines 500 along the length of the second mounting groove 106.

[0039] The setting of scale line 500 facilitates precise adjustment of the position of positioning block 109, ensuring the machining accuracy of the workpiece.

[0040] Preferably, the ends of the first screw 102 and the second screw 107 both extend to the outside of the worktable 100 and are equipped with a turntable 600, and a handle 601 is rotatably mounted on the outer surface of the turntable 600.

[0041] The turntable 600 and handle 601 enable workers to easily rotate the first screw 102 and the second screw 107.

[0042] Preferably, both the first mounting groove 101 and the second mounting groove 106 extend to the lower surface of the worktable 100.

[0043] After the workpiece is processed, such as by drilling or grinding, debris will remain on the surface of the worktable 100. Since the first mounting groove 101 and the second mounting groove 106 both extend to the lower surface of the worktable 100, the debris can be directly swept into the first mounting groove 101 and the second mounting groove 106 to fall off, and debris residue in the first mounting groove 101 and the second mounting groove 106 can be avoided.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
