Clamp

Abstract

The invention provides a clamp, which is used for clamping a to-be-processed part, and comprises a base, two clamping plates, a pressing plate, a supporting plate and a first driving device, wherein the two clamping plates are arranged on the base in a spaced manner; the pressing plate is arranged above the base, and two oppositely arranged ends of the pressing plate are separately connected to the two clamping plates; the supporting plate is arranged between the base and the pressing plate and is used for holding the to-be-processed part; and the first driving device is connected with the supporting plate, and is used for driving the supporting plate to drive the to-be-processed part to move to be attached to the pressing plate. When the to-be-processed part is clamped by the clamp provided by the technical scheme, as the pressing plate is fixed, the face, near the base, of the pressing plate and the face, far away from the support plate, of the to-be-processed part are installation reference planes, while for the to-be-processed part, such as a metal battery cover and the like, the upper surface of the to-be-processed part is a to-be-processed surface when a highlight C corner is processed, so that the installation reference planes are consistent with the to-be-processed surface, and therefore, the installation accuracy of the to-be-processed surface of the to-be-processed part, such as a metal battery cover and the like, can be increased, the accuracy of the processed highlight C corner can be further ensured, and the aesthetic property of the to-be-processed part, such as a metal battery cover and the like, can be improved.

Description

technical field [0001] The invention relates to the field of processing technologies such as mobile phone accessories, in particular to a clamp. Background technique [0002] At present, the high-brightness C angle is widely used on metal battery covers and other products, basically covering more than 95% of the products, and in order to obtain a delicate appearance, the clamping device plays a very critical role, but in the prior art, When processing a product (such as a metal battery cover) with a high-brightness C-angle, the product is generally placed on the pallet, and then a pressure plate is set above the pallet, and then the pressure plate is driven by the driving device to press the product on the pallet. Between the clamping method and the pressure plate, the installation reference plane of this clamping method is the inner surface of the product and the upper surface of the base, but the actual surface to be processed is the outer surface of the product, so that t...

[0002] At present, the high-brightness C angle is widely used on metal battery covers and other products, basically covering more than 95% of the products, and in order to obtain a delicate appearance, the clamping device plays a very critical role, but in the prior art, When processing a product (such as a metal battery cover) with a high-brightness C-angle, the product is generally placed on the pallet, and then a pressure plate is set above the pallet, and then the pressure plate is driven by the driving device to press the product on the pallet. Between the clamping method and the pressure plate, the installation reference plane of this clamping method is the inner surface of the product and the upper surface of the base, but the actual surface to be processed is the outer surface of the product, so that the surface to be processed of the product is inconsistent with the reference plane of installation and positioning , so the installation accuracy of the product surface to be processed will be affected by the processing accuracy and installation accuracy of the inner surface of the product and the upper surface of the base, so that the clamping error of the outer surface of the product is relatively large, and it is difficult to ensure the processing of the highlight C angle In the prior art, an automatic detection device is generally installed on the processing machine tool, and then the automatic detection device is used to detect and pick points to establish a new coordinate system, and feed back to the machine tool, and the machine tool adjusts the path according to the feedback information. To ensure the processing accuracy, but the price of the automatic detection device is expensive, which will increase the processing cost of the product. On the other hand, the use of the automatic detection device will double the processing time of the product, thus reducing the processing efficiency
