Description

Technical Field

[0001] The utility model relates to the technical field of spring grinding machines, in particular to a numerically controlled spring grinding machine with water washing and dust removal. Background Technique

[0002] In order to ensure the perpendicularity of the helical compression spring, and make the end faces of the two supporting rings keep in contact with other parts, reduce deflection and ensure the characteristics of the main machine (or parts). Generally, the end faces of the helical compression spring need to be ground, and this process is usually called spring grinding. A numerically controlled spring grinding machine is a machine tool that grinds the surface of a workpiece by using a grinding tool through numerical control technology.

[0003] In the prior art, when the numerically controlled spring grinding machine grinds the spring end face, it is often necessary to set up a dust removal device near the grinding tool of the numerically controlled spring grinding machine, and use the negative pressure adsorption effect of the dust removal device to collect the debris generated during the grinding process.

[0004] The above treatment of dust removal for the numerically controlled spring grinding machine requires the cooperation of an additional dust removal device on the one hand, and is inconvenient to use; on the other hand, during the process of sucking and collecting debris, the debris is prone to fly, affecting the dust removal effect. Therefore, we propose a numerically controlled spring grinding machine with water washing and dust removal to solve the above problems. Content of the Utility Model

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 to 3 , a numerically controlled spring grinding machine with water washing and dust removal, which may include a machine tool 10, a horizontal translation mechanism 20, a longitudinal translation mechanism 30, a top grinding component 40, and two groups of bottom grinding components 50. The horizontal translation mechanism 20 is installed on the top of the machine tool 10, and the horizontal translation mechanism 20 has a first moving part that moves horizontally. The longitudinal translation mechanism 30 is installed on the first moving part of the horizontal translation mechanism 20, so that the horizontal translation mechanism 20 can drive and adjust the horizontal position where the longitudinal translation mechanism 30 is located. The longitudinal translation mechanism 30 has a second moving part that moves longitudinally, and the top grinding component 40 is installed on the second moving part of the longitudinal translation mechanism 30, so that the longitudinal translation mechanism 30 can drive and adjust the longitudinal position of the top grinding component 40. The two groups of bottom grinding components 50 are installed below the machine tool 10, and the tops of the two groups of bottom grinding components 50 protrude to the processing table surface of the machine tool 10. The top grinding component 40 is movably arranged above the two groups of bottom grinding components 50, and the end faces of the spiral spring located between the two can be ground simultaneously by using the top grinding component 40 and the bottom grinding component 50 that are vertically aligned.

[0022] In this embodiment, the machine tool 10 is a conventional structure of a grinding machine in the prior art, which can be used to place parts to be processed, support and install the required processing components and control systems, and will not be elaborated here.

[0023] In this embodiment, the lateral translation mechanism 20 and the longitudinal translation mechanism 30 can both be implemented with the same structure, and the difference between the two may only lie in the different moving directions and moving distances of the first movable part and the second movable part. For example: both the lateral translation mechanism 20 or the longitudinal translation mechanism 30 can include a guiding bracket, a driving motor, a ball screw, and a screw seat. The ball screw is arranged inside the guiding bracket, one end of the ball screw is supported and connected to the inner side wall of the guiding bracket by a bearing, and the other end of the ball screw can be connected and driven to rotate by the driving motor installed and fixed on the guiding bracket. The screw seat is slidably connected to the guiding bracket, and the screw seat is in screw transmission connection with the ball screw, so that when the ball screw rotates, the position of the screw seat can be adjusted, so that the screw seat can constitute the first movable part of the lateral translation mechanism 20 or the second movable part of the longitudinal translation mechanism 30. It can be understood that the lateral translation mechanism 20 and the longitudinal translation mechanism 30 can also adopt other existing linear transmission structures in the prior art, such as being driven by a linear motor, a gear and rack transmission structure, etc.

[0024] In this embodiment, the top grinding component 40 includes a top grinding wheel 41, a three-way pipe 42, two connecting pipes 43, and four spray heads 44. The upper end of the top grinding wheel 41 is rotatably connected to the second movable part, and the top grinding wheel 41 can be driven to rotate by a transmission belt existing in the prior art. An inwardly concave area is formed at the bottom of the top grinding wheel 41, the upper end of the three-way pipe 42 passes through the inwardly concave area to the upper part of the top grinding wheel 41, and the upper end of the three-way pipe 42 can be connected to an external water pump by a hose, so that water can be input into the three-way pipe 42. The lower ends of the three-way pipe 42 are respectively communicated with the two connecting pipes 43, the ends of the connecting pipes 43 away from the three-way pipe 42 are respectively communicated with the two spray heads 44, the spray ports of the spray heads 44 face the edge of the inwardly concave area, and the water introduced into the three-way pipe 42 can be input to the spray heads 44 through the connecting pipes 43, and is sprayed out through the spray ports on the spray heads 44 for adsorbing dust and debris.

[0025] In this embodiment, the bottom grinding component 50 can both include a grinding motor, a flange, and a bottom grinding wheel. The output end of the grinding motor is clamped with the middle part of the flange by a flat key, so that the output end of the grinding motor can drive the flange to rotate. The bottom grinding wheel is detachably connected to the flange by bolts, the bottom grinding wheel is located above the processing table of the machine tool 10, the grinding motor is located below the processing table of the machine tool 10, and a sealing ring is installed at the gap between the machine tool 10 and the bottom grinding component 50 to prevent the grinding motor from being affected by the sprayed water.

[0026] When grinding a helical spring, a disc-shaped tooling can be used to place a number of helical springs to be ground. Corresponding through-holes are formed in the disc-shaped tooling for placing the helical springs, and the thickness of the disc-shaped tooling is slightly less than the height of the helical spring, so that the upper and lower ends of the helical spring can be exposed and contact with the grinding wheel. During the grinding operation, the original tooling is placed on the grinding wheel of a set of bottom grinding components 50, and after the grinding wheel in the top grinding component 40 moves to contact the top of the spring, the upper and lower ends of the helical spring can be ground by the rotation of the two sets of grinding wheels. After grinding, the grinding wheels in the top grinding component 40 and the bottom grinding component 50 both stop rotating. At this time, the top grinding component 40 moves above another set of bottom grinding components 50 to continue the operation. The tooling operator can remove the ground spring and place a new spring to be ground on the corresponding stopped bottom grinding component 50. The above disc-shaped tooling can also be clamped between the two sets of grinding wheels by a robotic arm, so that the disc-shaped tooling can be prevented from falling off the grinding wheel due to the force and shaking during the grinding process.

[0027] The system of the present invention may further include a control system for controlling operations of the above-mentioned motor and water pump, etc., so as to perform automatic operations of grinding and spraying for dust removal. It should be understood that there is no particular limitation on this control system, and it can be implemented by control technologies in the prior art, which will not be elaborated here.

[0028] In all the solutions mentioned above, for the connection between two components, welding, connection with bolts and nuts, connection with bolts or screws, or other well-known connection methods can be selected according to the actual situation, which will not be elaborated one by one here. For those mentioned above that involve fixed connection, welding is preferably considered. Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
