Problems solved by technology

Among them, machine grinding has the disadvantages of large equipment, high capital occupation, and troublesome maintenance. It is not easy to obtain for small enterprises. Different size pipe grinding requires different tools
In the existing manual grinding, the operator usually directly grinds with the grinding tool in hand, which is inefficient and limited to the grinding of small-diameter pipe fittings, and the processing of larger pipe fittings is time-consuming and labor-intensive.

Abstract

The invention discloses a semiautomatic grinding machine which comprises a bracket, a feeding device, a clamping device, a grinding head and a handle, wherein the bracket comprises an inner bracket and an outer bracket; each of the inner bracket and the outer bracket consists of supporting shafts, pressing wheels and an end part connection block; each of the inner bracket and the outer bracket comprises at least two supporting shafts; at least two pressing wheels are arranged on each supporting shaft; the pressing wheels are connected with the supporting shafts in a rotatable manner; the feeding device is connected to the supporting shafts of the outer bracket in a sliding manner; the grinding head is mounted on the feeding device; the semiautomatic grinding machine is characterized in that the feeding device drives the grinding head to carry out spiral feeding along the outer surface of a pipe fitting; the feeding device comprises a sliding plate and an adjustment device mounted on the sliding plate; and the adjustment device is used for adjusting the feeding speed and the spiral feeding angle. Compared with the prior art, the semiautomatic grinding machine disclosed by the invention has multiple excellent technical effects, and is simple and compact in structure, convenient to carry and operate, low in cost and wide in application range.

Description

technical field [0001] The invention relates to a grinding device, in particular to a semi-automatic grinding machine for pipe fittings Background technique [0002] Existing pipelines usually need to use welding technology or connectors to connect short pipelines together. At this time, the surface quality of the pipelines directly affects the reliability and sealing performance of the connected pipelines. To this end, it is necessary to grind the ends of the two pipes to be connected, so as to remove rust and surface defects on the outer surface of the pipe fittings, so that the pipe ends can be reliably connected and fixed together. [0003] The existing grinding methods include machine grinding and manual grinding. Among them, machine grinding has disadvantages such as large equipment, high capital occupation, and troublesome maintenance. It is relatively difficult for small enterprises to obtain. At the same time, this equipment can only be used for processing pipe fit...
