Description

Technical Field

[0001] The present invention relates to the field of grinding machines, and in particular to a feeding system and method for a double-end surface grinding machine. Background Art

[0002] The double-end surface grinder is a highly efficient plane processing machine tool that can grind two parallel end surfaces simultaneously in one processing process. It can be divided into horizontal and vertical types according to its structure, and can be divided into through-type, rotary table type, and reciprocating type according to the feeding method.

[0003] For example, a commonly used rotary disc double-disc grinder requires a push mechanism to push the workpiece onto the disc to be processed. However, this push mechanism is relatively simple, employing only a columnar structure to store the workpiece and a horizontal mechanical structure to push the workpiece. This push mechanism can easily cause the workpiece to deflect and interfere as it moves onto the disc, compromising machining quality. Summary of the Invention

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0034] The following combination Figures 1 to 6 The present invention describes a feeding system and method for a double-end surface grinding machine.

[0035] In one embodiment, a feeding system for a double-end face grinder is provided, the system comprising a fixed seat 100, a short plate rack 210, a long plate rack 220, a fiber layer and an inserting plate 600; a transverse accommodating groove 110 is provided on the side of the fixed seat 100, the double-end face grinder body 10 is located on one side of the fixed seat 100, one side of the turntable 20 of the double-end face grinder body 10 is located in the transverse accommodating groove 110, and a longitudinal accommodating groove 120 connected to the transverse accommodating groove 110 is provided on the top surface; the short plate rack 210 is provided on the top surface of the fixed seat 100 and is located on one side of the longitudinal accommodating groove 120; the long plate rack 220 is provided on the top surface of the fixed seat 100 and is located on the other side of the longitudinal accommodating groove 120; the limiting layer 300 is installed on the long plate rack 220, and its surface faces the short plate rack 210; the inserting plate 600 is installed transversely in the transverse accommodating groove 110, and is used to support the workpiece between the limiting layer 300 and the short plate rack 210.

[0036] Specifically, when in use, the spacing between the limiting layer 300 and the long plate frame 220 is adjusted so that the limiting layer 300 can cooperate with the short plate frame 210 to clamp and limit the workpiece, and then the workpiece is placed from above the long plate frame 220 and the short plate frame 210. The limiting layer 300 will push and limit multiple workpieces so that the workpieces always remain in one position. At this time, the double-end face grinder body 10 is started, and the turntable 20 thereon will be partially located in the horizontal receiving groove 110. When the area on the turntable 20 for placing the workpiece moves to directly below the workpiece, the insert plate 600 moves horizontally, and the workpiece supported on the insert plate 600 will fall onto the turntable 20 and be sent away during the rotation of the turntable 20 for double-end face processing.

[0037] The feeding system of the double-end face grinder adjusts the spacing between the limiting layer 300 and the long plate frame 220 during use, so that the limiting layer 300 can cooperate with the short plate frame 210 to clamp and limit the workpiece. The workpiece is then placed from above the long plate frame 220 and the short plate frame 210. The limiting layer 300 pushes and limits the multiple workpieces, so that the workpieces always remain in one position. At this time, the double-end face grinder body 10 is started, and the turntable 20 on it will be partially located in the horizontal receiving groove 110. When the area on the turntable 20 for placing the workpiece moves to directly below the workpiece, the insert plate 600 moves horizontally, and the workpiece supported on the insert plate 600 will fall onto the turntable 20 and be sent away during the rotation of the turntable 20 for double-end face processing. This feeding method can limit the area and position of the workpiece, avoid deflection and interference during movement, and ensure the processing quality.

[0038] In one embodiment, a pushing member 400 is installed on the long board frame 220, and the end of the pushing member 400 is movably connected to the limiting layer 300, which is used to push the limiting layer 300 towards or away from the short board frame 210, and a fastener 500 is installed between two adjacent limiting layers 300 or between the limiting layer 300 and the short board frame 210, which is used to fasten the two adjacent limiting layers 300 or the limiting layer 300 and the short board frame 210.

[0039] Specifically, the top surface of the fixing base 100 is further provided with a guard plate 130, which is located on one side of the longitudinal receiving slot 120. The two ends of the guard plate 130 are bent downward and connected to the top surface of the fixing base 100. The lower portion of the guard plate 130 defines a mounting cavity 131, which communicates with the transverse receiving slot 110. Limiting ribs 132 are provided on both sides of the mounting cavity 131. Fourth limiting slots 620 are defined on both sides of the insert plate 600, and the limiting ribs 132 are engaged in the fourth limiting slots 620. The side of the insert plate 600 facing the longitudinal receiving slot 120 is provided as a supporting surface 610.

[0040] In one embodiment, the short board rack 210 is configured as a semicircular plate-shaped structure. A slot 211 is defined at the bottom end of the short board rack 210, into which the guard plate 130 is engaged. A first limiting slot 212 is defined at the side end of the short board rack 210. The long board rack 220 is formed by two first curved plates 221. The first curved plates 221 are provided with a plurality of mounting holes 222 spaced apart in the vertical direction. Second limiting slots 223 are defined at the side ends of the first curved plates 221 spaced apart in the vertical direction. The lowermost second limiting slot 223 is located at the same horizontal height as the first limiting slot 212. The height of the short board rack 210 is less than that of the first curved plates 221. A placement opening 230 is formed between the upper portion of the first curved plates 221 and the top of the short board rack 210.

[0041] Specifically, the first limiting groove 212 and the second limiting groove 223 in this embodiment are both arranged in a semicircular structure, and the surface is covered with threads. The first limiting groove 212 and the second limiting groove 223 can be combined to form a threaded hole, and the threaded hole is used to install the fastener 500, thereby realizing the limiting fixation of the short plate frame 210 and the long plate frame 220.

[0042] In one embodiment, the limiting layer 300 includes two clamping plates 310, a second curved plate 320 and two third curved plates 330; the two clamping plates 310 are respectively clamped on the two side ends of the first curved plate 221, the second curved plate 320 is located between the two clamping plates 310, and the bottom end of the second curved plate 320 extends into the longitudinal accommodating groove 120, and the two side ends of the second curved plate 320 are respectively connected to the two clamping plates 310 through two third curved plates 330, and the bending direction of the third curved plate 330 is toward the first curved plate 221.

[0043] Specifically, during installation, the clamping plates 310 are vertically positioned over both ends of the first curved plate 221. The arc openings of the second and third curved plates 320 and 330 are both oriented away from the first curved plate 221, and the arc length of the third curved plate 330 is shorter than that of the second curved plate 320. When the second curved plate 320 is pushed, it deforms. Because the third curved plate 330 has a greater bend and a shorter arc length, it deforms first, leaving the second curved plate 320 to preferentially conform to the workpiece.

[0044] In one embodiment, the limiting layer 300 further includes a plurality of positioning tubes 340 , which are vertically spaced apart on a side of the second curved plate 320 facing the first curved plate 221 , and a third limiting groove 311 is further defined on the clamping plate 310 .

[0045] Specifically, the pushing member 400 is threadedly installed in the mounting hole 222, the end of the pushing member 400 is rotatably installed in the positioning tube 340, and the fastener 500 is threadedly installed between the first limiting groove 212 and the second limiting groove 223, between the two second limiting grooves 223 or between the two third limiting grooves 311.

[0046] In one embodiment, a feeding method for a double-disc grinder is applied to the feeding system of the double-disc grinder according to any of the above embodiments, comprising the following steps:

[0047] The workpiece is placed between the short plate rack 210 and the long plate rack 220 and dropped onto the upper surface of the inserting plate 600 to complete the support of the workpiece.

[0048] Before the workpiece is fed, there is a variable interval between the limiting layer 300 and the long plate frame 220, so that the limiting layer 300 can be changed according to the size of the workpiece, thereby clamping the workpiece.

[0049] When the turntable 20 rotates to a suitable position, the inserting plate 600 moves linearly in the horizontal direction, and the workpiece falls into the position to be processed on the turntable 20.

[0050] The feeding method of the double-end face grinder is to adjust the spacing between the limiting layer 300 and the long plate frame 220 during use so that the limiting layer 300 can cooperate with the short plate frame 210 to clamp and limit the workpiece. The workpiece is then placed from above the long plate frame 220 and the short plate frame 210. The limiting layer 300 will push and limit the multiple workpieces so that the workpieces always remain in one position. At this time, the double-end face grinder body 10 is started, and the turntable 20 thereon will be partially located in the horizontal receiving groove 110. When the area on the turntable 20 for placing the workpiece moves to directly below the workpiece, the insert plate 600 moves horizontally, and the workpiece supported on the insert plate 600 will fall onto the turntable 20 and be sent away during the rotation of the turntable 20 for double-end face processing. This feeding method can limit the area and position of the workpiece, avoid deflection and interference during movement, and ensure the processing quality.

[0051] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
