TECHNICAL FIELD

[0001] The utility model relates to clamping assembly technical field, especially machine vice balanced clamping assembly. BACKGROUND

[0002] Machine vice is a device for clamping workpieces, commonly used in metal processing and mechanical processing fields. It is usually composed of clamping arms, fixed seats, pull rods, movable tool holders and other components, and the rapid clamping of workpieces is achieved through pull rod operation. Machine vice is usually used to clamp various types of workpieces, especially metal parts such as aluminum alloy, steel, copper and other parts. These workpieces may include milled surfaces, punched workpieces, workpieces before welding and workpieces that need to be machined or manufactured

[0003] A new type of bidirectional machine vice is disclosed in Chinese patent (authorized publication number CN214641913U). The patent technology includes a vice body; the vice body includes a vice body and a fixed jaw; the vice body is provided with two clamping stations respectively located on both sides of the fixed jaw; the new type of bidirectional machine vice further includes multiple sets of auxiliary positioning arms; the auxiliary positioning arm includes a transverse connecting arm, two sets of suction cups corresponding to the two clamping stations, and a positioning pin fixed to the middle of the connecting arm; the two sets of suction cups are respectively fixed to the two ends of the connecting arm; the upper surface of the fixed jaw is provided with multiple positioning grooves adapted to the positioning pins; the multiple positioning grooves are linearly arranged, and the arrangement direction of the multiple positioning grooves is the same as the length direction of the fixed jaw. After improvement, the workpiece does not need to be held when the handle is turned, and the use is more convenient.

[0041] In order to make the purpose, technical scheme and advantages of the utility model more clear, the embodiments of the utility model will be described in further detail below with reference to the drawings.

[0042] Example 1

[0043] Please refer to Figures 1-6 The embodiment is a machine vice balanced clamping assembly, comprising,

[0044] The clamping structure 100 comprises a base 101, support plates 104 located on both sides of the upper end of the base 101, screw holes 105 opened in the inside of the support plates 104, screw rods 103 threadedly installed with the screw holes 105, rotating rods 102 arranged in a ring array on the outer wall of the screw rods 103, stroke plates 108 rotationally installed at one end of the screw rods 103, guide rails 107 fixedly arranged on the upper end of the base 101, and sliding blocks 106 slidingly installed in the inside of the guide rails 107 and located at the lower end of the stroke plates 108.

[0045] The balanced structure 200 comprises rotating seats 213 symmetrically arranged at one end of the stroke plates 108, an adjusting seat 201 located in the inside of the rotating seats 213, rotating shafts 212 rotationally installed at both ends of the adjusting seat 201 and the rotating seats 213, abutting grooves 205 arranged in a ring array on the outer wall of the adjusting seat 201, modules 202 inserted into the inside of the abutting grooves 205, and mounting holes 204 opened on the outer wall of the modules 202.

[0046] The inside of the upper end of the base 101 slidingly inserts a middle plate 109, both ends of the middle plate 109 are provided with side plates 110, the inside of the base 101 and the side plates 110 are both provided with positioning holes 111, and the inside of the positioning holes 111 slidingly inserts positioning blocks 112.

[0047] Both ends of the modules 202 are provided with insertion holes 203, the inside of the adjusting seat 201 is provided with stroke grooves 206 and stroke holes 208 arranged in a ring array and installed in communication with the abutting grooves 205, and one end of an insertion rod one 207 located in the inside of the insertion holes 203 slidingly inserts the inside of the stroke holes 208 and the stroke grooves 206.

[0048] One end of the insertion rod one 207 located outside the adjusting seat 201 is provided with a pull handle 211, the outer wall of the insertion rod one 207 is sleeved with a limiting ring one 209 located in the inside of the stroke grooves 206, and one end of the limiting ring one 209 is provided with a spring one 210 connected with the inner wall of the stroke grooves 206 and sleeved on the outer side of the insertion rod one 207.

[0049] The balanced structure 200 is used;

[0050] Module 202 is pre-connected to clamping plates with flat, flexible, or irregularly shaped surfaces to adapt to the shapes and properties of common workpieces. The fasteners are installed through mounting holes 204. Module 202 is then inserted into the mating groove 205. During this process, the pull rod is pre-pulled, causing the insertion rod 207 to move. A limiting ring 209 applies pressure to the spring 210. After module 202 is positioned inside the mating groove 205, the pull rod is relaxed. The elastic force of the spring 210 causes one end of the insertion rod 207 to be inserted into the insertion hole 203, elastically engaging module 202. Module 202 is easy to install and facilitates the replacement of clamping plates with different properties and specifications. The outer side of the adjusting seat 201 has six sets of frequently used clamping plates. During use, rotating the adjusting seat 201 aligns the clamping blocks of the corresponding workpieces.

[0051] The gripping handle 102 and the stroke plate 108 slide inside the guide rail 107 via the slider 106. Rotationally mounted with the screw 103, the screw 103 moves, causing the stroke plate 108 to move, which in turn pushes the adjusting seat 201 and the clamping plate at one end of the module 202 to clamp the workpiece. During use, simply rotating the adjusting seat 201 ensures that the corresponding clamping plate always clamps the workpiece during processing, facilitating the clamping of workpieces of different specifications and properties. This achieves balanced adaptation of the machine vise, ensuring that the forces, pressures, weights, or other physical quantities of each part are equal and counteract each other during operation or movement. In the vise's balanced clamping assembly, by achieving balance, the force applied to the workpiece during clamping is evenly distributed, improving clamping effect and operational stability.
