Description

Technical Field

[0001] The invention relates to the technical field of hydraulic valve processing, and in particular to a hydraulic valve precision component processing device. Background Art

[0002] A hydraulic valve is a component used in a hydraulic system to control the pressure, flow rate and flow direction of a fluid. Some common precision components in hydraulic valves include valve bodies, valve cores, seals, end covers, etc. The valve core is the core component of the hydraulic valve, which controls the passage of the fluid by moving. The shapes of the valve cores are usually cylindrical, conical, and spherical. For the grinding of spherical valve cores, it is usually necessary to grind the outer wall and inner hole of the spherical embryo of the spherical valve core.

[0003] At present, during the grinding process of the spherical valve core, a grinding wheel or a polishing machine is usually used for processing. Before processing, the spherical valve core is clamped and limited by a positioning piece or a fixture. However, the grinding of the spherical valve core is usually performed one by one, and manual loading is required one by one. The efficiency of loading and clamping is low, and it is not conducive to continuous operation. Secondly, in order not to affect the grinding effect of the outer wall of the ball embryo, a positioning piece inserted into the inner hole of the spherical valve core ball embryo is usually used for limiting. The limiting effect needs to be improved, and it is not conducive to the grinding operation of the inner hole of the spherical valve core ball embryo, and there are grinding dead angles.

[0044] Reference Figures 5 and 6 The side wall of the hollow rod 42 is symmetrically and slidably connected with an adjusting sub-component 45, and the adjusting sub-component 45 consists of an arc segment connected to the side wall of the hollow rod 42 by a spring and a pushing block fixed to the arc segment. The pushing block of the adjusting sub-component 45 slides through the side wall of the hollow rod 42, and a toothed disc 46 is rotatably penetrated through the top wall of the discharge barrel 31. The toothed disc 46 and the discharge barrel 31 are connected by a positioning bolt 47 that is snap-fitted into the toothed disc 46. The top wall of the discharge barrel 31 is provided with a plurality of holes that are compatible with the positioning bolt 47.

Before the lower feeding barrel 31 and the feeding hole 1 34 move to the next lower grinding seat 51, the feeding hole 1 34 and the feeding hole 2 36 interlace to block the ball valve core to be ground from falling, thereby realizing batch intermittent feeding of the ball valve core to be ground, thereby improving the automation level of the device.

The wedge sub-component 84 is adapted to the wedge master component 2 75, and the wedge sub-component 86 is adapted to the wedge master component 1 74 and the wedge master component 3 76.

[0054] When the fixing plate 56 moves downward, the positioning mechanism 7 is driven to approach the grinding mechanism 2 8 , and the positioning seat 2 81 plays a positioning role on the ball valve core to be ground. The positioning mechanism 7 moves downward into the interior of the positioning seat 2 81 until the positioning member 1 72 and the positioning member 2 82 are engaged.

[0055] The bottom output end of the positioning member 72 moves downward, driving the wedge block mother member 2 75 to move downward. The downward movement of the wedge block mother member 2 75 pushes the wedge block sub-member 1 84 to slide from the inside to the outside on the outer wall of the positioning seat 2 81. The grinding sheet 83 then moves away from the side wall of the positioning seat 2 81 and fits tightly against the inner hole of the ball embryo of the ball valve core to be polished which is sleeved on the outside of the positioning seat 2 81. The spring is stretched to adapt to the inner holes of the ball embryos of ball valve cores of different sizes, thereby increasing the practicality of the device.

[0056] The output end of the motor 2 63 on the support mechanism 2 rotates to drive the corresponding gear 61 to rotate, and the toothed belt 62 is used for transmission, and other gears 61 rotate accordingly, driving the connected lower grinding seat 51 to rotate, and the lower grinding seat 51, the upper grinding seat 57 and the ball valve core rotate as a whole at the same time, so as to fully grind the side wall of the ball valve core in contact with the side grinding seat 54.

[0057] While the lower grinding seat 51, the upper grinding seat 57 and the ball valve core rotate as a whole at the same time, the output end of the motor 2 63 on the grinding mechanism 1 5 rotates to drive the corresponding gear 61 to rotate, and the toothed belt 62 is driven, and the other gears 61 rotate accordingly, driving the connected positioning mechanism 7 to rotate, and the grinding mechanism 2 8 engaged with the positioning mechanism 7 rotates accordingly. The rotation direction of the grinding mechanism 2 8 is opposite to the rotation direction of the lower grinding seat 51, and the grinding plate 83 grinds the inner hole of the ball embryo of the ball valve core, so as to achieve sufficient grinding of the inner hole wall of the ball embryo of the ball valve core while grinding the side wall in contact with the side grinding seat 54, thereby improving the grinding efficiency.

[0058] The bottom output end of the positioning member 1 72 drives the wedge mother member 1 74 and the wedge mother member 3 76 to move downward until the wedge mother member 1 74 and the wedge mother member 3 76 push the corresponding wedge sub-member 2 86 to slide on the side wall of the positioning seat 2 81 from the inside to the outside, and the rubber strip 85 moves away from the side wall of the positioning seat 2 81, and the rubber strip 85 is close to the inner hole wall of the ball embryo of the ball valve core. The rubber strip 85 increases the resistance, and the positioning mechanism 7 and the grinding mechanism 2 8 rotate to drive the ball valve core to rotate as a whole, so that the top wall and the bottom wall of the ball valve core are ground on the outer wall of the upper grinding seat 57 and the lower grinding seat 51, reducing the dead angle of grinding and making the grinding effect better.

[0059] The specific operation steps of this hydraulic valve precision component processing device are as follows:

[0060] When the toothed disc 1 35 moves and meshes with the rack 23, the toothed disc 1 35 rotates to drive the discharge hole 2 36 to rotate from an interlaced state with the discharge hole 1 34 to an overlapping state, and then from the overlapping state to an interlaced state, in this cycle. Before the lower barrel 31 and the discharge hole 1 34 move to the next lower grinding seat 51, the discharge hole 1 34 and the discharge hole 2 36 are interlaced to block the ball valve core to be ground from falling, thereby realizing batch intermittent discharge of the ball valve core to be ground.

[0061] The lower grinding seat 51 supports the ball valve core to be polished, and the upper grinding seat 57 moves down to the bottom wall to be close to the top wall of the ball valve core to be polished, so that multiple ball valve cores to be polished are simultaneously limited and clamped by the upper grinding seat 57, the lower grinding seat 51 and the side grinding seat 54 at the same time, thereby improving the clamping efficiency.

[0062] The lower grinding seat 51 rotates, and the lower grinding seat 51, the upper grinding seat 57 and the ball valve core rotate as a whole at the same time, so as to fully grind the side wall of the ball valve core in contact with the side grinding seat 54, and the motor 2 63 on the grinding mechanism 1 5 drives, and the rotation direction of the grinding mechanism 2 8 is opposite to the rotation direction of the lower grinding seat 51, and the grinding sheet 83 grinds the inner hole of the ball embryo of the ball valve core, so as to fully grind the inner hole wall of the ball embryo of the ball valve core while grinding the side wall in contact with the side grinding seat 54, and the bottom output end of the positioning member 1 72 drives, and the rubber strip 85 is away from the side wall of the positioning seat 2 81, and the rubber strip 85 is close to the inner hole wall of the ball embryo of the ball valve core, and the rubber strip 85 increases the resistance, and the positioning mechanism 7 and the grinding mechanism 2 8 rotate to drive the ball valve core to rotate as a whole, so that the top wall and the bottom wall of the ball valve core are grinded on the outer wall of the upper grinding seat 57 and the lower grinding seat 51, reducing the dead angle of grinding.
