Abstract
The utility model belongs to the field of hold-down equipment and particularly relates to a plate edge hold-down device. The hold-down device comprises a bottom plate, wherein a hold-down table is arranged in the middle of the bottom plate. The hold-down device is characterized in that a mounting groove is arranged on the left side of the hold-down table; a guide rail is arranged at the bottom of the mounting groove; a slide block with a gear rack is arranged on the guide rail; the hold-down device further comprises a rotatable rotating shaft connected onto the wall of the mounting groove; a pressing block is connected with the right end of the rotating shaft; a gear matched with the slide block is arranged below the rotating shaft; a hydraulic cylinder is arranged on the right side of the hold-down table of the bottom plate; and the output end of the hydraulic cylinder is connected with the slide block. According to the design of the hold-down device, the hydraulic cylinder is adopted for driving and the gear rack on the upper surface of the slide block is matched with the gear of the rotating shaft, so as to realize the rotation of the pressing block; therefore, a plate part is clamped, automatic clamping is realized, manual operation is reduced, and the clamping speed is improved.
Description
Technical field
The utility model belongs to the compression apparatus field, particularly a kind of hold down gag of sheet edge.
Background technology
In mechanical processing process, all need carry out a location and locking to part to be processed, the location is used to guarantee that the precision of processing, locking can prevent flying out of part in the process, has prevented the generation of contingency.
The U-shaped pressing plate is often adopted in the common clamping to plate material parts; Realize compressing through screw rod and cushion block to sheet material; There is following deficiency in this mode that compresses: 1, the very big power of screw rod when locking needs, and not so loosening easily, 2, screw rod thread failure can occur several times easily in use; Need often to change screw rod, cost is high.
Summary of the invention
The utility model is to the problems referred to above; The utility model has designed a kind of employing Driven by Hydraulic Cylinder, and the tooth bar through the slide block upper surface cooperates with the gear of rotating shaft, thereby realizes the rotation of briquetting; Promptly realized clamping to plate material parts; Realize the automation that clamps, reduced manual work, improved the speed that clamps.
Hold down gag, it comprises base plate, the middle part of base plate is provided with and compresses platform; It is characterized in that: be provided with a mounting groove in the left side that compresses platform, the bottom of mounting groove is provided with guide rail, and guide rail is provided with the slide block with tooth bar; Also comprise being connected rotary rotating shaft on the cell wall is installed, the right-hand member of rotating shaft is connected with briquetting, and the below of described rotating shaft is provided with the gear that cooperates with slide block; The right side that compresses platform of base plate is provided with hydraulic cylinder, and the output of hydraulic cylinder is connected with slide block.
In sum, the utility model comes the rotation of driving sliding block through hydraulic cylinder, is convenient to realize the operation of automation; Hydraulic cylinder has the big characteristics of pressure with respect to cylinder simultaneously, and the utility model adopts hydraulic cylinder to guarantee the strength that pressing plate compresses, and has guaranteed the effect that compresses; The utility model is simple in structure simultaneously; Be convenient to manufacture, and production cost is bigger, can large-scale promotion.
Description of drawings
Fig. 1 is the structural representation of the utility model;
1 is base plate among the figure, and 2 is slide block, and 3 is guide rail, and 4 is output, and 5 is hydraulic cylinder, and 6 is briquetting, and 7 for compressing platform, and 8 is mounting groove.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Hold down gag as shown in Figure 1, it comprises base plate 1, the middle part of base plate 1 is provided with and compresses platform 7; The platform that compresses that is provided with is used to place sheet material, is provided with a mounting groove 8 in the left side that compresses platform 7, and the bottom of mounting groove 8 is provided with guide rail 3; Guide rail 3 is provided with the slide block 2 with tooth bar, and slide block 2 can also comprise being connected rotary rotating shaft on mounting groove 8 walls in the enterprising line slip of guide rail; The right-hand member of rotating shaft is connected with briquetting 6; The below of described rotating shaft is provided with the gear that cooperates with slide block 2, and the right side that compresses platform 7 of base plate 1 is provided with hydraulic cylinder 5, and the output 4 of hydraulic cylinder 5 is connected with slide block 2; The utility model moves through the Driven by Hydraulic Cylinder slide block, thereby drives compressing and unclamping of depression bar.
In sum, the utility model comes the rotation of driving sliding block through hydraulic cylinder, is convenient to realize the operation of automation; Hydraulic cylinder has the big characteristics of pressure with respect to cylinder simultaneously, and the utility model adopts hydraulic cylinder to guarantee the strength that pressing plate compresses, and has guaranteed the effect that compresses; The utility model is simple in structure simultaneously; Be convenient to manufacture, and production cost is bigger, can large-scale promotion.
