Embodiment 1

[0018] like figure 1 As shown, the positionable valve grinding device includes a motor 1, a chuck and a hand sleeve 2 are connected in sequence under the motor 1, a grinding disc 7 and a pressure plate 8 are connected in sequence under the hand sleeve 2, and a The pressure positioning block located above the grinding disc 7, the pressure positioning block includes an adjustable bracket 4 and a handle 3 arranged on the adjustable bracket 4, the upper part of the adjustable bracket 4 is engraved with a pointer 6, and the lower part of the adjustable bracket 4 is provided with Scale, also be provided with rolling bearing in the adjustable support 4, adjustable support 4 is fixed on the fixed pendulum seat 5 by bolt. There is a pressure positioning block on the grinding device, on the one hand, it can exert a compressive force on the grinding disc, so that the grinding disc 7 can be in good contact with the surface to be processed for easy processing; The grinding disc is aligned...

Embodiment 2

[0021] like figure 1 and figure 2 As shown, the fixed swing seat 5 includes an upper fixed swing seat 501, an intermediate connector 503, and a lower fixed swing seat 502. The upper fixed swing seat 501 and the lower fixed swing seat 502 are bolted together through the intermediate connector 503. The balanced setting of the fixed pendulum seat 5 can stably fix the valve grinding device on the valve, so that the grinding disc of the valve grinding device can be aligned with the center of the surface to be processed.

[0022] The intermediate connecting piece 503 is a separate upper and lower section, and the upper and lower sections are connected by an external thread on the upper section and an internal thread on the lower section.

Abstract

The invention discloses a valve grinding device capable of performing positioning. The valve grinding device comprises a motor, a chuck and a handheld sleeve are sequentially connected below the motor, a grinding disk and a pressing plate are sequentially connected below the handheld sleeve, a pressure adjusting device located above the grinding disk is further connected to the handheld sleeve, the pressure adjusting device comprises a pressure adjusting handle, the pressure adjusting handle is installed on a pressure adjusting rotating cover, an adjustable support is connected below the pressure adjusting rotating cover, and the adjustable support is fixed to a fixing swing base through a bolt. The pressure adjusting device is arranged on an existing valve grinding device capable of performing positioning, acting force applied to the grinding disk can be adjusted through the pressure adjusting handle, the acting force on the grinding disk can be prevented from being too large to too small, and therefore the valve grinding device is more favorable for grinding work and convenient and fast to use.

Description

technical field [0001] The invention relates to a valve grinding device which can be positioned, in particular to a valve grinding device which can be finely adjusted and used by multiple parties for a cut-off valve. Background technique [0002] The grinding of the valve is the grinding of the sealing surface of the valve. The grinding of the sealing surface of the valve is not a direct contact between the grinding head or the grinding seat and the disc or seat to be ground, but a pad or a layer of grinding material. To use the particles with high hardness of the abrasive material to polish the abrasive piece. [0003] The existing valve grinding device cannot accurately locate the grinding depth when grinding the valve seat, but only grinds the valve seat according to estimation, which may easily cause excessive or insufficient grinding. Contents of the invention [0004] The invention provides a positionable valve grinding device, which can precisely position the grind...
