Embodiment Construction
[0014] The multi-degree-of-freedom mechanical fixture provided by the present invention has a structure such as Figure 1 to Figure 3 As shown: there is an up and down moving body 8 and a lateral moving body 20, which are slidably connected by moving up and down guide rods 6; Above, the rod body is connected with the laterally moving body through a linear bearing, and is connected with the up and down moving body 8 through guide sleeves (21). There is a screw 23, one end of which is connected to the support 1 fixed on the vertical reference plane through a bearing, and the other end is connected to the DC geared motor 15 through the coupling 14 in the bearing seat 13, and its rod body is connected to the lateral movement through the nut 22. Ontology connected. A sample transfer cylinder 27 is provided, the piston rod of which is connected to the receiving bin 10 through the connecting piece, that is, the cylinder threaded joint 28 and the cylinder ejection joint 29, and the r...

The invention provides a mechanical fixture with multiple degrees of freedom and with the structure that the fixture is provided with an up-and-down moving body (8) and a transverse moving body (20) which are connected through an up-and-down moving guide bar (6) and a guide sleeve (21) in a slide way; two transmission guide bars (3) are provided, and two ends of the transmission guide bars are fixed on a vertical base level of a frame through a support base (2) and each bar body is respectively connected with the transverse moving body through a bearing; a screw rod (23) is provided and connected with a direct current deceleration motor (15) through a coupling (14) and the rod body is connected with the transverse moving body through a nut (22); a sample shifting cylinder (27) is provided, and a piston rod of the cylinder is connected with a charging bin (10) through a connecting part and the charging bin is connected with an extending slide channel (11) on the up-and-down moving body in a slide way; and a top sample direct current deceleration motor (18) is arranged on the up-and-down moving body. The invention can cause workpieces to move back and forth, right and left and up and down in multiple degrees of freedom and clamp the workpieces; and the up and down location is accurate, which simplifies the design of electrical appliances and reduces the cost.
Description
technical field [0001] The invention relates to a fixture, in particular to a multi-degree-of-freedom mechanical fixture for steel samples. Background technique [0002] In the process of cutting and grinding steel conical bar samples, in order to combine the two processes into one, it is necessary to complete material receiving during cutting, sample transfer, height detection before grinding, clamping, and finally Grinding completes the entire sample preparation process. At present, the situation of the same type of products in foreign countries is: this process is realized by manipulators, most of which use servo motors, which increases the product cost, and the working principle of electrical appliances is also complicated. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a mechanical fixture with multi-degree-of-freedom movement, which is used for receiving, clamping and transferring steel conical bar sample...
