Abstract
The utility model discloses a work fixture for a frame structure, which comprises a bracket, as well as a hydraulic cylinder and a control system which are arranged on the bracket, wherein the end part of the hydraulic cylinder is connected with a clamping element, a pressure sensor is arranged on the hydraulic cylinder or the clamping element, and a displacement sensor is arranged on the hydraulic cylinder. In the utility model, a displacement signal is acquired through actions of the hydraulic cylinder, a pressure signal is obtained through the gripping force of the hydraulic cylinder to a workpiece, the two signals are transmitted to the control system, the control system is used for making comparison between a pre-set program and the obtained signals so as to control the gripping force and the action displacement of the hydraulic cylinder, can achieve automatic and accurate positioning, is convenient to operate, and can greatly reduce the labor intensity of workers, and the welding efficiency is high.
Description
Technical field
The utility model relates to a kind of frame structure frock clamp.
Background technology
Generally to be the workman in welding process weld powerful clamping of workpiece with crowbar large-scale workpiece, perhaps the workman with brute force with the workpiece weld seam to fetching welding; Large-scale workpiece is easy to generate distortion in welding process, in the weld seam docking operation, the excesssive gap between two workpiece can cause the wide difficult welding of weld seam, thereby increases workman's working strength, and welding efficiency is low.
The utility model content
The purpose of the utility model provide a kind of can automatic pinpoint frame structure frock clamp.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of frame structure frock clamp comprises support and is arranged at hydraulic cylinder and the control system on the support that cylinder ends is connected with clamping element, and one of said hydraulic cylinder and clamping element are provided with pressure sensor, and hydraulic cylinder is provided with displacement transducer.
Said pressure sensor is located in the hydraulic cylinder rodless cavity.
In the utility model, through hydraulic cylinder workpiece is clamped and to weld, on one of hydraulic cylinder and clamping element, be provided with pressure sensor; Displacement transducer is set on hydraulic cylinder, obtains displacement signal, through the clamping force acquisition pressure signal of hydraulic cylinder workpiece through the action of hydraulic cylinder; Two signals are passed to the control system, and comparison is done by pre-set program and the signal of obtaining by the control system, controls the clamping force and the action displacement of hydraulic cylinder; Can realize accurately locating automatically; Easy to operate, can reduce working strength of workers greatly, welding efficiency is high.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Embodiment 1: as shown in Figure 1, the frame structure frock clamp comprises support 1 and is arranged at the hydraulic cylinder 3 and control system 2 on the support 1; Hydraulic cylinder 3 has four; Be arranged at support 1 both sides, hydraulic cylinder 3 ends are connected with clamping element 5, and said hydraulic cylinder 3 is provided with displacement transducer 4; Said hydraulic cylinder 3 is provided with pressure sensor 6, and pressure sensor 6 is located in the rodless cavity of hydraulic cylinder 3.
Embodiment 2: in the present embodiment, pressure sensor 6 is located at and is stepped up on the part 5, puts on the work that the size of stepping up the power on the part 5 is controlled hydraulic cylinder 3 through basis, and other are with embodiment 1.
In the utility model, four groups of hydraulic valve bank are controlled four hydraulic cylinders 3 respectively, from the both sides of frock welding work pieces are clamped, and hydraulic cylinder 3 can be realized a plurality of actions that clamp: promptly four cylinders move simultaneously, one-sided two functions such as oil cylinder synchronization action; And hydraulic cylinder 3 also can be implemented in the pressurize of any position, plays the lasting clamping force to workpiece.During welding; Displacement signal is obtained in action through hydraulic cylinder 3, and the clamping force acquisition pressure signal through 3 pairs of workpiece of hydraulic cylinder passes to control system 2 with two signals; Comparison is done by pre-set program and the signal of obtaining by control system 2; Control the clamping force and the action displacement of hydraulic cylinder 3, the location is accurate, and welding efficiency is high.
Claims (2)
1. frame structure frock clamp; Comprise support and be arranged at hydraulic cylinder and the control system on the support, cylinder ends is connected with clamping element, it is characterized in that; One of said hydraulic cylinder and clamping element are provided with pressure sensor, and hydraulic cylinder is provided with displacement transducer.
2. frame structure frock clamp as claimed in claim 1 is characterized in that said pressure sensor is located in the hydraulic cylinder rodless cavity.
