Description
Technical field
The utility model belongs to pressing device, and in particular to a kind of auxiliary clamping device for workpiece pressing.
Background technology
When workpiece needs to compress, frequently with the mode being pressed on workpiece between shoring and auxiliary clamping device, and will
The pressing force of auxiliary clamping device is asked to be less than the support force of shoring.Existing auxiliary clamping device is equipped with pneumatic cylinder, pneumatic cylinder
Workpiece is pressed on shoring by pressurization, but due to the limited pressure that pneumatic cylinder is capable of providing, existing auxiliary clamping device is normal
Pressing force deficiency is commonly present, compresses the problem of ineffective；And usually without considering using hydraulic pressure in existing auxiliary clamping device
Cylinder, this is because the pressure of Normal hydraulic cylinder is excessive, it has been more than that shoring tolerance range is depressurized, it is necessary to configure pressure reducing valve,
Otherwise it is easy to damage shoring.
Utility model content
The utility model is intended to provide a kind of auxiliary clamping device, to provide suitable pressing force so that workpiece is reliable
Compression, while the parts such as pressure reducing valve need not be increased.
For this purpose, technical solution is used by the utility model：
A kind of auxiliary clamping device including external screw thread single- acting cylinder, mounting base and holds down assembly, and the mounting base is equipped with
The mounting groove of the external screw thread single- acting cylinder is fitted into, and the mounting base is equipped with the oil circuit hole connected with mounting groove, the pressure
Tight component is connected with the piston of external screw thread single- acting cylinder, when compressing or unclamping workpiece, is pressurizeed or is let out to mounting groove by oil circuit hole
Pressure holds down assembly and work is compressed or unclamped under the driving of external screw thread single- acting cylinder to drive the piston motion of external screw thread single- acting cylinder
Part, the piston external diameter of the external screw thread single- acting cylinder is 12mm-25mm.
Further, hold down assembly including briquetting and connecting rod, described connecting rod one end is hinged in mounting base, and the other end is articulated with
On briquetting, described briquetting one end is hinged on the piston of external screw thread single- acting cylinder, and the other end is in the collective effect of piston and connecting rod
Lower pushing or rising.This structure to hold down assembly causes to form a branch on briquetting with the hinged mode of briquetting using connecting rod
Point, when fulcrum is located at different position on briquetting, the arm of force of fulcrum both sides changes, and can design the position of the fulcrum according to demand
It puts so that briquetting is located to the pressure that workpiece applies in suitable section.
As the preferred of said program, the mounting base is equipped with to shorten the convex block of length of connecting rod, the convex block and peace
Tankage is located at mounting base homonymy, and the connecting rod is hinged on the convex block.The convex block can shorten length of connecting rod so that connecting rod rigidity is more
Good, service life is longer.
The beneficial effects of the utility model：
The auxiliary clamping device is simple in structure, can apply suitable pressing force to workpiece so that workpiece reliably compresses
On shoring.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the top view of Fig. 1.
Specific embodiment
By way of example and in conjunction with the accompanying drawings, the utility model is described in further detail：
As shown in Figure 1, Figure 2, a kind of auxiliary clamping device, including external screw thread single- acting cylinder 2, mounting base 1 and compression group
Part 3.
The piston external diameter of external screw thread single- acting cylinder 2 is 12mm-25mm.
Mounting base 1 is equipped with the mounting groove for fitting into the external screw thread single- acting cylinder 2, and the mounting base 1 is equipped with and peace
The oil circuit hole 11 of tankage connection.
Holding down assembly 3 includes briquetting 31 and connecting rod 32, and 32 one end of connecting rod is hinged in mounting base 1, and the other end is articulated with pressure
On block 31,31 one end of briquetting is hinged on the piston of external screw thread single- acting cylinder 2, and the other end is in the collective effect of piston and connecting rod 32
Lower compression or release workpiece.This 3 structure of holding down assembly is caused using connecting rod 32 and the hinged mode of briquetting 31 on briquetting 31
A fulcrum is formed, when fulcrum is located at different position on briquetting 31, the arm of force of fulcrum both sides changes, and can set according to demand
Count the position of the fulcrum so that briquetting 31 is located to the pressure that workpiece applies in suitable section.
When workpiece pressing, pressurizeed by oil circuit hole 11 to mounting groove the piston of external screw thread single- acting cylinder 2 to be driven to stretch out,
Hold down assembly 3 briquetting 31 under the piston of external screw thread single- acting cylinder 2 and the collective effect of connecting rod 32 with suitable pressing force will
Workpiece is pressed on shoring.
When unclamping workpiece, pressure release is reserved by hydraulic oil in 11 mounting groove of oil circuit hole, external screw thread single- acting cylinder 2
Piston is retracted, and 3 briquetting 31 of holding down assembly unclamps work under the piston of external screw thread single- acting cylinder 2 and the collective effect of connecting rod 32
Part.
Convex block 12 is preferably provided in mounting base 1, which is located at the homonymy of mounting base 1 with mounting groove, and connecting rod 32 is cut with scissors
It is connected on the convex block 12,32 length of connecting rod can be shortened so that 32 rigidity of connecting rod is more preferable, and service life is longer.It is being embodied
In the process, which can be bolted in mounting base 1, can also be integrally formed and set with mounting base 1.
