Description

Technical Field

[0001] The utility model belongs to the technical field of cutting equipment, and particularly relates to a workpiece fixing device for a cutting equipment. Background Art

[0002] In modern manufacturing, cutting equipment is widely used in the processing of various materials, such as metals, plastics, composite materials, etc. In order to ensure cutting accuracy and improve production efficiency, the workpiece to be cut needs to be stably fixed on the working table of the cutting equipment. The existing workpiece fixing devices usually use clamps or pressing mechanisms to fix the workpiece. However, for an evaporator that needs to be cut, such devices have relatively large defects. Since the edge of the evaporator is relatively weak, when the pressing force of the pressing mechanism is too large, the evaporator will have a curling phenomenon; moreover, there is a lack of buffer measures during the pressing process of the pressing mechanism, so that the impact force during pressing will damage the surface of the evaporator. Content of the Utility Model

An elastic member 500 is provided between the driving structure 400 and the adjusting plate 300. When the adjusting plate 300 moves to abut against the workpiece in the receiving groove 210, the elastic member 500 exerts a reverse acting force on the driving structure 400. It provides buffering for the workpiece when it is fixed, thereby reducing damage to the workpiece, avoiding the phenomenon of curling of the evaporator, and effectively ensuring the integrity and performance of the workpiece.

[0030] Specifically, as Figures 1 to 4 shown, in this embodiment, the base 100 includes a load-bearing platform 110 and a base plate 120 detachably arranged on the load-bearing platform 110. The load-bearing platform 110 is a hollow structure and serves as the load-bearing structure of the workpiece fixing device. The detachable design of the load-bearing platform 110 and the base plate 120 enables users to easily adjust, replace, and maintain relevant components according to needs, increasing the versatility and convenience of the device.

[0031] In this embodiment, the mounting plate 200 is detachably arranged on one side of the base plate 120 facing away from the load-bearing platform 110, and the adjusting assembly is detachably arranged on one side of the base plate 120 facing the load-bearing platform 110, and the adjusting assembly is located inside the load-bearing platform 110, making the working area above the base plate 120 more concise, effectively improving the convenience of user operation. At the same time, this detachable design enables users to replace different models of mounting plates 200 according to usage requirements.

[0032] In this embodiment, the mounting plate 200 is rectangular, and is provided with a rectangular accommodating groove 210 for placing a workpiece, so as to fix the workpiece and ensure the stability of the workpiece during the cutting process.

[0033] Preferably, in this embodiment, the mounting plate 200 is detachably connected to the substrate 120 through a quick-release joint 800, which improves the efficiency of the user in replacing the mounting plate 200. In addition, handles 240 are provided on both sides of the mounting plate 200, effectively improving the convenience for the user to pick up the mounting plate 200.

[0034] To fix workpieces of different models, in this embodiment, limiting grooves 220 for the abutting portions 340 to pass through are provided on both the base 100 and the mounting plate 200. The limiting grooves 220 extend along the length direction of the mounting plate 200, so that the abutting portions 340 can extend into the limiting grooves 220 to move and adjust the size of the accommodating groove 210, thereby realizing the fixation of workpieces of different models.

[0035] Preferably, in this embodiment, three groups of the limiting grooves 220 are provided to be adapted to the adjusting plate 300.

[0036] To prevent the cutting tool from damaging the surface of the mounting plate 200 during the cutting of the workpiece. In this embodiment, a plurality of cutting grooves 230 perpendicular to the limiting grooves 220 are provided on the mounting plate 200. The cutting grooves 230 are recessed toward the substrate 120 for the cutting tool to extend into. It can not only protect the mounting plate 200, but also reduce the wear of the tool.

[0037] In this embodiment, the adjusting assembly includes an adjusting plate 300 movably extending into the accommodating groove 210, and a driving structure 400 detachably provided on the side of the substrate 120 away from the mounting plate 200. The driving structure 400 drives the adjusting plate 300 to move along the length direction of the limiting groove 220 in the accommodating groove 210. An elastic member 500 is provided between the driving structure 400 and the adjusting plate 300. When the adjusting plate 300 moves to abut against the workpiece in the accommodating groove 210, the elastic member 500 exerts a reverse acting force on the driving structure 400 to buffer the impact of the adjusting plate 300 on the workpiece, thereby reducing the damage to the workpiece and effectively ensuring the performance of the workpiece.

[0038] In this embodiment, the adjustment plate 300 vertically passes through the limiting groove 220 and extends into the accommodating groove 210, and is provided with two groups of symmetrically arranged weight-reducing grooves 330, which extend along the length direction of the adjustment plate 300, so that the adjustment plate 300 is formed with three abutting portions 340 arranged in a line, and when the adjustment plate 300 moves to abut against the workpiece, the abutting portions 340 are respectively fitted with the outer wall of the workpiece to ensure the stability of the workpiece fixation. The design and coordination of the weight-reducing grooves 330 and the abutting portions 340, while ensuring the contact area with the workpiece, also reduces the weight of the adjustment plate 300 and reduces the driving force required by the driving member 410.

[0039] In this embodiment, the driving structure 400 is arranged perpendicular to the adjustment plate 300, and extends through the adjustment plate 300 in a direction away from the adjustment plate 300, and the elastic member 500 is arranged between the extended end of the driving structure 400 and the adjustment plate 300. When the driving structure 400 drives the adjustment plate 300 to move, the elastic member 500 moves synchronously. When the adjustment plate 300 moves to abut against the workpiece, the adjustment plate 300 applies pressure to the elastic member 500, so that the elastic member 500 applies a reverse force to the driving structure 400, thereby achieving a buffer for the clamping of the workpiece.

The cooperation between the limiting sleeve 420 and the elastic member 500 enables the elastic member 500 to be compressed and expanded only along the length direction of the limiting sleeve 420 when deformed by pressure, thereby avoiding lateral movement of the elastic member 500 during the compression process, thereby ensuring the accuracy of the movement of the adjustment plate 300.

[0042] In this embodiment, the limiting sleeve 420 includes two limiting portions 421 respectively located on both sides of the adjusting plate 300, the diameter of the limiting portion 421 is larger than the diameter of the first through hole 310, and one end of the elastic member 500 abuts against the adjusting plate 300, and the other end abuts against the limiting portion 421 on the side of the limiting plate away from the driving member 410, which effectively prevents the adjusting plate 300 from falling off the limiting sleeve 420, thereby ensuring the integrity of the structure.
