Drawings
The invention is further illustrated with reference to the following figures and examples.
FIG. 1 is a first block diagram of the present invention;
FIG. 2 is a block diagram of the present invention;
FIG. 3 is a front view of the present invention;
fig. 4 is a schematic view of a partial structure of the spur and the auxiliary rubber strip of the present invention.
Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below.
As shown in fig. 1 to 4, a fixing device is used in processing of automobile water pump, including mounting bracket 1, be equipped with the well upper portion of two slant mounting brackets 1 on mounting bracket 1 and be the centre gripping arm 2 of symmetric distribution, pinion 3 is all installed in the swing center department of two centre gripping arms 2, pinion 3 all meshes has rack 4 with mounting bracket 1 horizontal sliding fit, be equipped with the double lead screw 5 that both ends link to each other with rack 4 respectively on mounting bracket 1 just double lead screw 5 is connected with actuating mechanism 6.
All connect the arm length direction of perpendicular to centre gripping arm 2 on the free end of centre gripping arm 2 and be the bur 7 of symmetry setting, bur 7 distributes in a row along the fore-and-aft direction of centre gripping arm 2 and has a plurality of, bur 7 all is equipped with supplementary rubber strip 8 along the upper and lower both sides of the arm length direction of centre gripping arm 2.
The driving mechanism 6 comprises a driven gear 61 arranged in the middle of the double-head screw 5 and a motor 63 engaged with the driven gear 61 and connected with a driving gear 62.
The height of the auxiliary rubber strip 8 is larger than that of the bur 7 along the direction vertical to the arm length of the clamping arm 2.
The tops of the spurs 7 are all in round corner transition.
When the auxiliary rubber strip is used, the auxiliary rubber strip 8 firstly contacts the surface of a workpiece and is pre-fixed to the workpiece through extrusion force and friction force, and finally the bur 7 acts on the workpiece to clamp the workpiece.
When the double-head screw rod clamping device is used, the motor 63 rotates forwards to drive the driving gear 62 to rotate, the driving gear 62 is meshed with the driven gear 61 to drive the double-head screw rod 5 to rotate, so that the two racks 4 on the mounting frame 1 move close to each other, and the clamping arm 2 turns downwards to clamp a workpiece; when the size of the workpiece is long, the motor 63 rotates reversely, the double-head screw 5 drives the two racks 4 to move away from each other, so that the clamping arm 2 overturns outwards to clamp the workpiece, and the workpiece is convenient to machine.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
