Multi-angle multi-station drill clamp

Abstract

The invention discloses a multi-angle multi-station drill clamp. The multi-angle multi-station drill clamp comprises a valve sleeve positioning block for clamping a valve sleeve, wherein the valve sleeve positioning block is a cuboid, and internally provided with a storage cavity; a fastening device is arranged on one side of the storage cavity; through holes which penetrate through the outer wall of the valve sleeve positioning block and are communicated to the storage cavity are formed in the valve sleeve positioning block; and the through holes correspond to drill holes of the valve sleeve in the storage cavity in positions and angles. According to the multi-angle multi-station drill clamp adopting the structure, before the valve sleeve is drilled, the valve sleeve is firstly placed in the storage cavity of the valve sleeve positioning block and fastened through the fastening device; and due to the fact that the through holes in the valve sleeve positioning block correspond to the drill holes of the valve sleeve in the storage cavity in positions and angles, the valve sleeve does not need to be carried out angle measurement, and a drill rod directly extend into the through holes so as to drill the valve sleeve in accurate positions.

Description

technical field [0001] The invention relates to a production tool for a valve sleeve, in particular to a multi-angle and multi-station drilling jig. Background technique [0002] The hydraulic valve is an automatic component operated by pressure oil. It is controlled by the pressure oil of the pressure distribution valve. It is usually used in combination with an electromagnetic pressure distribution valve. It can be used to remotely control the on-off of oil, gas, and water pipeline systems in hydropower stations. Clamping, control, lubricating and other oil circuits are divided into direct-acting type and pilot type, and the pilot type is mostly used. [0003] The valve sleeve is an important part of the hydraulic valve. figure 1 It is a structural schematic diagram of a valve sleeve. like figure 1 As shown, in the production process of the valve sleeve 1 , it is necessary to drill a plurality of holes 101 at different angles and positions on the valve sleeve 1 .

Problems solved by technology

However, in the prior art, there is no special fixture when drilling the valve sleeve, and the operator needs to use an angle measuring device to determine the drilling position and drilling angle. It is not necessarily very accurate, so it is easy to deviate too much in the drilling position, resulting in a high defective rate of valve sleeve production

At the same time, there is no special tooling for the drilling of the valve sleeve, and the operator has to repeatedly rotate and measure the valve sleeve when drilling holes, which results in low production efficiency and cannot meet the requirements of mass production
