Description

Technical fields:

[0001] This utility model relates to the field of hydraulic clamping technology, and specifically to a horizontal pressure-holding hydraulic clamp. Background technology:

[0002] Aluminum profiles are a widely used aluminum processed product in daily life. Depending on the application, the size and cross-sectional shape of aluminum profiles vary. Therefore, clamping aluminum profiles requires the use of specialized fixtures to ensure stable fixation and prevent movement or deformation during processing. During clamping, the aluminum profile must be positioned quickly to ensure positioning accuracy, and movement or offset should be avoided to prevent impacting work efficiency and processing quality.

[0003] Currently, there are tooling fixtures on the market that can position workpieces. For example, Chinese utility model patent application CN211192917U discloses a fixture for processing aluminum profiles, which includes: a base box, the inner cavity of which is provided with a first clamping mechanism, the first clamping mechanism including a stepper motor, the stepper motor being fixedly installed on the bottom left side of the base box, the output end of the stepper motor being fixedly connected to a bidirectional threaded rod, the left and right ends of the bidirectional threaded rod being threadedly connected to threaded sleeves, the top of the threaded sleeve being fixedly connected to a first bracket, the inner side of the first bracket being fixedly connected to a clamping plate, and the left and right ends of the top of the base box being provided with a second clamping mechanism, the second clamping mechanism including a second bracket. The provision of the first and second clamping mechanisms effectively improves the clamping effect and prevents workpiece displacement and movement, thereby avoiding damage and ensuring the processing effect and quality. The stepper motor drives the bidirectional threaded rod to rotate, thereby moving the threaded sleeves.

[0004] However, this existing aluminum profile processing fixture still has the following shortcomings:

[0005] In this technical solution, an external controller is required to activate the electric push rod to move the clamping plate downwards so that the workpiece can be clamped through the clamping slot and the second anti-slip pad. This is not convenient to operate. In addition, this technical solution can only process a single aluminum profile at a time, and the processing efficiency is very limited.

[0006] In view of the above, the inventors propose the following technical solution. Utility Model Content:

[0012] Further, in the above technical scheme, the number of pedestal supports is two, and a plurality of through holes for reducing mass are arranged on the pedestal supports.

[0013] Further, in the above technical scheme, a sequence valve for driving the end face positioning oil cylinder to contract is arranged on the pedestal, and an internal rack and pinion is also arranged on the pedestal and in transmission connection with the positioning rod and used for driving the positioning rod to swing; when the hydraulic socket is connected with the external oil pipe and the hydraulic pressure flows through the sequence valve, the sequence valve drives the end face positioning oil cylinder to contract, and drives the internal rack and pinion to rotate, so that the positioning rod swings to open.

[0014] Further, in the above technical scheme, an accumulator in communication with the hydraulic socket and used for driving the clamping assembly to clamp aluminum profiles is arranged on the base, and a gas-tight interface for enhancing gas tightness is also arranged beside the accumulator.

[0015] Further, in the above technical solution, the number of the clamping assemblies is four, and correspondingly, four mounting grooves for mounting the clamping assemblies are arranged on the stand.
