Embodiment 1

[0049] like figure 1 Said, the part to be processed comprises the inner hole of a straight section and the inner hole of an arc section, and one end of the inner hole of the arc section is connected with one end of the inner hole of the straight section, and the arc inner hole is connected with the straight inner hole. cut.

[0050] like figure 2 and image 3 As shown, a high-efficiency two-way synchronous grinding machine for pipe fittings provided by the embodiment of the present invention includes:

[0051] The base 50 is provided with a guide chute 51, and the extension track of the guide chute 51 is a standard arc segment;

[0052] Driving device, it comprises electric telescopic rod 20, drive block 21, first connecting rod 22, second connecting rod 23 and slide block 24, and driving block 21 is fixedly connected to the output end of electric telescopic rod 20, and electric telescopic rod 20 is used for Drive driving block 21 to move, and one end of first connecting ...

Embodiment 2

[0064] On the basis of Example 1, due to the small machining allowance and high dimensional accuracy requirements during grinding, frequent inspection after grinding is required, which reduces the efficiency of processing and inspection, so as Figure 4 As shown, the first grinding shaft 10 includes a first relief section, a first inspection section 103 and a first stop section 104, the diameter of the first relief section is smaller than the diameter of the inner hole of the straight section of the workpiece, and the first inspection section 103 The outer diameter of section 103 is the lower limit value of the inner hole diameter of the straight section of the workpiece, the outer diameter of the first stop section 104 is the upper limit value of the inner hole diameter of the straight section of the workpiece, and the diameter of the first relief section is smaller than the straight section to be processed. The diameter of the hole in the segment. During the grinding process...

Embodiment 3

[0072] On the basis of Embodiment 1 or 2, since the grinding head with a fixed size is used for many times, the outer diameter of the grinding head will become smaller, resulting in a smaller diameter of the grinding hole, and it is necessary to replace the new grinding head frequently, resulting in processing The cost is higher, so in this embodiment, such as Figure 7 to Figure 10 As shown, 4, the first grinding head 101 and the second grinding head 301 both include a first support block 11, a second support block 12, a connecting rod 106, an elastic pad 108 and a grinding layer 107, the first The support block 11 and the second support block 12 are connected through the connecting rod 106; the output end of the first feeding telescopic rod 60 is fixedly connected to the first support block in the first grinding head 101 11 or the second support block 12, the output end of the second feeding telescopic rod 70 is fixedly connected to the first support block 11 or the second s...

The grinding machine comprises a base, wherein a guide sliding groove is formed in the base; the driving device comprises an electric telescopic rod, a driving block, a first connecting rod, a second connecting rod and a sliding block; when the electric telescopic rod acts, the driving block drives the first grinding shaft and the second grinding shaft to act synchronously; the step removing device comprises a first processor, a first wireless receiving and transmitting module, a first feeding telescopic rod, a second processor, a second wireless receiving and transmitting module and a second feeding telescopic rod; a first storage chamber is formed in the first grinding shaft, and a second storage chamber is formed in the second grinding shaft; the first feeding telescopic rod is fixedly arranged in the first storage chamber; and the second feeding telescopic rod is fixedly arranged in the second storage chamber. According to the method, the junction can be polished, and small steps or junction marks at the junction can be removed.

Description

[0001] This application is a divisional application, the original patent number is: 202110098007.1, the application date is January 25, 2021, and the title of the invention is: a synchronous grinding machine with two-way internal holes for step removal. technical field [0002] The invention relates to the field of machining, in particular to a high-efficiency bidirectional synchronous grinding machine for removing steps of pipe fittings. Background technique [0003] In the field of product processing, it is a common processing method to process the inner hole of the product. For some precision parts, there are high requirements on the precision size of the inner hole and the surface roughness. Generally, for external dimensions, such as the outer diameter of rods or parts, which are easy to process, the dimensional accuracy can be effectively guaranteed by grinding machines. However, for the inner hole, due to the inconvenience of controlling the feed and the small machin...
