Description

Technical Field

[0001] The utility model relates to the technical field of four-station hydraulic clamps, in particular to a four-station hydraulic clamp. Background Art

[0002] In the field of processing, CNC processing is an important process that cannot be ignored in the production process.

[0003] At present, the processing method of CNC machining is clamping with precision flat-nose pliers. This operation and clamping method has many steps and is very cumbersome, and it is also inconvenient to disassemble.

[0004] In addition, some parts to be processed have relatively precise requirements on dimensions and appearance. During CNC processing, the support workpiece is clamped by manually tightening the clamping structure, which requires a high level of technical proficiency of the processing workers.

[0005] Since there are enlarged holes inside the workpiece to be processed, if the clamping force is too large during clamping, it will cause the part to deform and the accuracy will decrease. Secondly, only one part can be processed at a time during clamping, which has low processing efficiency and labor intensity for workers.

[0006] Therefore, in the utility model patent application, the applicant carefully studied a four-station hydraulic clamp to solve the above problems. Utility Model Content

[0007] The utility model aims to overcome the deficiencies of the above-mentioned prior art, and its main purpose is to provide a four-station hydraulic clamp, which can realize the simultaneous processing of four parts, greatly improving the processing efficiency, and preventing the hydraulic clamp from being operated by non-professionals, effectively improving the safety of the operating authority of the hydraulic clamp, and ensuring the professionalism of the hydraulic clamp.

[0008] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0009] A four-station hydraulic clamp comprises a bottom plate, a main control unit and four stations located on the upper end surface of the bottom plate and arranged at intervals along the front-rear direction thereof, each station being provided with a hydraulic clamp;

[0010] The rear end surface of the bottom plate extends horizontally to the left to form an extension portion, and a fingerprint identifier is provided on the lower end surface of the extension portion;

[0011] The main control unit is connected to the fingerprint identifier and the hydraulic clamp respectively so that the operation of the hydraulic clamp can be controlled only after the fingerprint is correctly identified.

[0012] As a preferred solution, the hydraulic clamp includes two clamping jaws and a hydraulic drive unit for driving the two clamping jaws to open and close, and the hydraulic drive unit is connected to the main control unit.

[0013] As a preferred solution, the hydraulic drive unit includes a hydraulic cylinder and a first connecting block and a second connecting block which are symmetrical and slidably connected to the inside of the hydraulic cylinder;

[0014] A piston rod is slidably connected inside the hydraulic cylinder, and the left and right sides of the front end of the piston rod respectively have a first inclined surface and a second inclined surface which are symmetrically arranged;

[0015] The first connecting block and the second connecting block are respectively connected to a clamping claw; the inner side surfaces of the first connecting block and the second connecting block respectively correspond to the first inclined surface and the second inclined surface and have a third inclined surface and a fourth inclined surface;

[0016] The first inclined surface and the second inclined surface are arranged together in an eight-shaped shape, and the third inclined surface and the fourth inclined surface are arranged obliquely outward from front to back.

[0017] As a preferred solution, the first inclined surface and the second inclined surface of the piston rod are respectively provided with a first T-shaped sliding block and a second T-shaped sliding block along the inclined surface direction thereof;

[0018] The third inclined surface of the first connecting block is provided with a first T-shaped sliding groove with a rear end opening, and the first T-shaped sliding block is adapted to fit in the first T-shaped sliding groove;

[0019] The fourth inclined surface of the second connecting block is provided with a second T-shaped sliding groove with a rear end opening, and the second T-shaped sliding block is adapted to fit in the second T-shaped sliding groove.

[0020] As a preferred solution, the first connecting block and the second connecting block are detachably connected to corresponding clamping jaws.

[0021] As a preferred solution, the four workstations are arranged at equal intervals.

[0022] Compared with the prior art, the utility model has obvious advantages and beneficial effects, specifically:

[0023] It mainly realizes the simultaneous processing of four parts by setting four workstations at intervals along the front and back directions of the bottom plate and each workstation is provided with a hydraulic clamp, which greatly improves the processing efficiency. In particular, the hydraulic clamp is protected by fingerprint recognition to prevent the hydraulic clamp from being operated by non-professionals, effectively improving the safety of the hydraulic clamp's operating authority and ensuring the professionalism of the hydraulic clamp.

[0024] Secondly, through the cooperation of multiple inclined surfaces, only one piston rod can be used to control the opening and closing of the two clamping jaws at the same time, and the structure is more compact. Compared with the existing method in which each clamping jaw is driven by a single driving cylinder, the cost is lower and the space occupied is small;

[0025] Furthermore, the detachable structure design of the clamping jaws allows the clamping jaws of different sizes to be replaced according to the sizes of the workpieces to be processed, which has good versatility and is convenient for subsequent maintenance and replacement.

[0026] Furthermore, by adapting the corresponding T-shaped slider into the corresponding slide groove, the stability and reliability of the clamping jaws during the opening and closing process are ensured.

[0027] In order to more clearly illustrate the structural features and effects of the present invention, it is described in detail below in conjunction with the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS
