Description

A clamp with flip-type pressing plate

technical field

The utility model relates to the technical field of material processing and positioning, in particular to a fixture for fixing workpieces to be processed.

Background technique

Before processing workpieces such as mobile phone casings, it is usually necessary to use a fixture to fix the product. In order to improve the positioning accuracy and the efficiency of fixing operations, and to adapt to the fixing of various products, fixture devices are widely used to meet the fixing requirements. However, at present, most of the fixtures widely used in the industry are of a separate structure of the fixture base and the cover plate. Before the product is processed, the operator needs to place the cover plate from the outside of the CNC machine on the base inside the machine. The frequency of repeated removal and release of the pressure plate is high. , The labor intensity of the operator is high; in addition, the pressing plate is easy to be stained with debris outside the machine, and the surface is easy to be damaged, and it is easy to slip and accidentally injure the operator during the process of taking and placing. Moreover, the pressure plate is placed above the product, and after the cylinder is compressed, the fit between the pressure plate and the product is easily affected by the cylinder, thereby affecting the product processing effect. For this reason, someone has invented a fixture that can be turned over automatically to solve the problems caused by manual handling of the pressure plate. For example, the utility model patent No. 201520251833.5 discloses a kind of automatic turnover fixture, including a turntable and a matching tailstock, and between the turntable and the tailstock. There is a base plate in between, a support plate is provided on the upper surface of the base plate, a pressure plate is arranged above the support plate, a cylinder is fixed on the base plate, the cylinder is connected to the pressure plate, and one side of the part is fixed by the cylinder to process, and then the other side of the part is turned over by the motor. Processing, so that there is no need for secondary clamping, saving clamping time and reducing errors. However, the structure in which the entire body is turned over by the motor is quite complicated, and the way of passing through the bottom plate after turning over is very limited, making it difficult to perform comprehensive and flexible processing.

Utility model content

The technical problem to be solved by the utility model is to provide a clamp with flip-type pressing plate which has simple structure, reasonable design, convenient operation, good positioning effect and no influence on the processing process.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical scheme: a clamp with a flip-type pressing plate, including a clamp base, a bottom plate, a positioning plate and a pressing plate, the pressing plate is located above the positioning plate to press the product placed on the positioning plate, The positioning plate is installed on the bottom plate, and the bottom plate is installed on the fixture base. It is characterized in that: one side of the pressing plate is fixed on a pressing plate fixing seat through a pressing plate fixing shaft to form a movable structure that can be turned over, and the pressing plate fixing seat is installed on the bottom plate. ; There is a pressing bar that can be lifted and rotated on the pressing plate, and the pressing bar is connected with a power mechanism, and the pressing bar is controlled by the power mechanism to exert force on the pressing plate to form a pressing structure for the product.

Squeezing the movable pin by the elastic force of the spring can solve the problem of product misalignment caused by the unbalanced force of the product during the pressing process of the pressing plate. The principle is that the front end of the pressing plate moves downward (the pressing process), and the rear end (fixed shaft end ) Rely on the elastic force of the spring to lift the pressure plate to ensure that the pressure plate is balanced on the product first, and then apply pressure to compress the product.

Further, the rear end of the pressure rod is connected to the power mechanism through a pressure rod fixed shaft to form a liftable and horizontally rotatable structure of the pressure rod, and the pressure rod fixed shaft is connected to the power output end of the power mechanism.

Preferably, the power mechanism is an air cylinder, an oil cylinder, an electromagnet or a motor, among which an air cylinder is preferred.

Further, a pressure rod guide column is provided between the pressure rod fixing shaft and the edge of the pressure plate, the pressure rod guide column is close to the pressure plate and fixed on the bottom plate, and the pressure rod guide column is inserted into the pressure rod during the pressing down process. A guide structure is formed in the guide post hole to prevent the pressure rod from sliding sideways.

Further, the pressure plate is provided with an avoidance groove extending toward the middle of the pressure plate on the side adjacent to the pressure plate fixing seat, and a pressure plate limit post matching the escape groove is provided on the bottom plate, and the pressure plate is limited during the turning process of the pressure plate. The positioning post is in the avoidance groove, and the pressing plate limiting post can prevent the pressing plate from sliding and misaligning.

Further, a number of product limiting columns are arranged around the positioning plate, and the product limiting columns are arranged close to the edge of the positioning plate and fixed on the bottom plate.

Preferably, the side of the pressing plate in contact with the product is made of flexible material.

Description of the working process: Before taking and placing the product, turn the pressure bar to one side, and the operator manually turns the pressure plate up to take out or put the product. After placing the product, cover the pressure plate, turn the pressure rod to the top of the pressure plate to align with the pressure rod guide column, start the cylinder (or other power mechanism), and the cylinder drives the pressure plate to press down, thereby compressing the pressure plate. The process for opening the platen is reversed.

The utility model changes the traditional separate fixture pressing plate into an integrated flexible flip-type pressing plate to clamp products, and the operator can take and place the product by turning over the pressing plate. When the product is positioned, the power mechanism acts on the integrated flexible flip-type pressure plate through the pressure rod to compress the product, eliminating the need for employees to repeatedly pick and place the pressure plate, which can improve the fit between the pressure plate and the product, reduce damage to the pressure plate, and save costs. , Improve efficiency and improve operational safety.
