Abstract
The utility model relates to a four-bar clamping device which is characterized in that the device comprises a handle, a clamping arm, a four-bar mechanism and a cylinder, wherein the handle is connected with the clamping arm through a bolt and a pin; and the four-bar mechanism and the cylinder arranged below the four-bar mechanism are locked and connected through a cylinder head pin. The device mainly adopts the four-bar mechanism, the manual clamping and the pneumatic opening, has safe and reliable properties, is convenient for workpiece fitting, and can be effectively prevented from knocking or damaging car body, parts, etc. The device has the advantages of simple structure, reasonable design, remarkable effect, convenience for production, safe and reliable properties and wide application range.
Description
Technical field
The utility model relates to the weld jig in a kind of automobile making, particularly a kind of four connecting rod clamping devices.
Background technology
At present, along with automobile industry development at full speed, related industry is also constantly being carried out scientific and technical innovation; In the existing design of Clamping Apparatus, common clamp structure tends to the workpiece because the reason of dynamics is collided with in the moment of cylinder clamping, also is difficult to determine the exact position of small workpiece simultaneously.
Therefore, provide a kind of simple in structure, reasonable in design, use easy, obvious results four connecting rod clamping devices, be one of these those skilled in the art problem that should address.
The utility model content
The purpose of this utility model is to overcome above-mentioned weak point, and a kind of simple in structure, reasonable in design, easy to use, obvious results four connecting rod clamping devices are provided.
The technical scheme that the utility model adopted is for achieving the above object: a kind of four connecting rod clamping devices is characterized in that comprising handle, clamp arm, quadric chain and cylinder; Described handle is connected with pin by bolt with clamp arm; Described quadric chain is connected by the locking of cylinder head pin with the cylinder that places its below.
The beneficial effects of the utility model are: the main quadric chain that adopts of this device, and adopt manually clamping, and pneumatic opening, performance is safe and reliable, so that go up part and effectively prevent to collide with damage body of a motor car part etc.The utility model is simple in structure, and is reasonable in design, and effect is remarkable, is convenient to produce, and is widely used.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model operation logic schematic diagram;
Among the figure: 1 handle, 2 quadric chains, 3 cylinders, 4 templates, 5 clamp arms.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, details are as follows to the specific embodiment, structure, feature that foundation the utility model provides:
As shown in Figure 1, a kind of four connecting rod clamping devices is characterized in that comprising handle 1, clamp arm 5, quadric chain 2 and cylinder 3; Described handle 1 is connected with pin by bolt with clamp arm 5; Described quadric chain 2 is connected by the locking of cylinder head pin with the cylinder 3 that places its below.Workpiece template 4 places clamp arm 5.
Connect by bolt between each parts in this device, and locate with alignment pin.Whole mechanism is fixed on the fixture substrate by fixture.
The quadric chain operation logic is as follows:
As shown in Figure 2, wherein L4 makes L1 rotate around O2 for to decide bar with hand propelled handle 1, drives L2 with this, and makes L3 rotate the arrival clamped position around O1.Lock point position is used to locate the clamped position of L1, arrives locked-up point to guarantee quadric chain; And then, guarantee the reliability that clamps for the cylinder ventilation.When opening, L1 opens counterclockwise to cylinder ventilation driving, drives L2, L3 and opens anchor clamps.
Can before clamp, manually specific clamping unit be clamped, so that go up part or prevent to knock damage body of a motor car part.Lock point and point of rotation O2 can adjust simultaneously, guaranteeing the reliability of this structure clamping, and effectively improve the unfailing performance of anchor clamps.
Above-mentioned with reference to embodiment to the detailed description that four connecting rod clamping devices carry out, be illustrative rather than determinate; Therefore in the variation and the modification that do not break away under the utility model general plotting, should belong within the protection domain of the present utility model.
Claims (1)
1. a connecting rod clamping device is characterized in that comprising handle, clamp arm, quadric chain and cylinder; Described handle is connected with pin by bolt with clamp arm; Described quadric chain is connected by the locking of cylinder head pin with the cylinder that places its below.
