Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0034] Combine the following Figures 1 to 6 The 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 surface 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 insert plate 600; a transverse receiving groove 110 is provided on the side of the fixed seat 100, the double-end surface grinder body 10 is located on one side of the fixed seat 100, one side of the turntable 20 of the double-end surface grinder body 10 is located in the transverse receiving groove 110, and a longitudinal receiving groove 120 connected to the transverse receiving groove 110 is provided on the top surface; the short plate rack 210 is arranged on the top surface of the fixed seat 100 and is located on one side of the longitudinal receiving groove 120; the long plate rack 220 is arranged on the top surface of the fixed seat 100 and is located on the other side of the longitudinal receiving groove 120; the limiting layer 300 is installed on the long plate rack 220, and its surface faces the short plate rack 210; the insert plate 600 is installed transversely in the transverse receiving groove 110, and is used to support the workpiece placed between the limiting layer 300 and the short plate rack 210.

[0036] Specifically, during use, the interval 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 surface 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 surface processing.

[0037] The feeding system of the double-end face grinder adjusts the interval between the limiting layer 300 and the long plate frame 220 when in use, so that the limiting layer 300 can clamp and limit the workpiece in cooperation with the short plate frame 210, 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 the multiple workpieces so that the workpieces are always kept in one position. At this time, the double-end face grinder body 10 is started, and the upper turntable 20 will be partially located in the horizontal receiving groove 110. When the area on the turntable 20 for placing the workpiece moves to the bottom of 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 to perform double-end face processing.

[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 two adjacent limiting layers 300 or between the limiting layer 300 and the short board frame 210.

[0039] Specifically, a guard plate 130 is further provided on the top surface of the fixing seat 100. The guard plate 130 is located on one side of the longitudinal receiving groove 120. Both ends of the guard plate 130 are bent downward and connected to the top surface of the fixing seat 100. A mounting cavity 131 is formed below the guard plate 130. The mounting cavity 131 is connected to the transverse receiving groove 110. Limiting ribs 132 are provided on both sides of the mounting cavity 131. Fourth limiting grooves 620 are provided on both side ends of the plug plate 600. The limiting ribs 132 are clamped in the fourth limiting grooves 620. A side of the plug plate 600 facing the longitudinal receiving groove 120 is provided as a supporting surface 610.

[0040] In one embodiment, the short board frame 210 is provided in a semicircular plate-shaped structure, a slot 211 is provided at the bottom end of the short board frame 210, the guard plate 130 is clamped in the slot 211, and a first limiting slot 212 is provided at the side end of the short board frame 210. The long board frame 220 is composed of two first curved plates 221, a plurality of mounting holes 222 are provided at intervals along the vertical direction on the first curved plates 221, and second limiting slots 223 are provided at intervals along the vertical direction on the side ends of the first curved plates 221, and the lowermost second limiting slot 223 is at the same horizontal height as the first limiting slot 212, the height of the short board frame 210 is less than the height of the first curved plates 221, and a placement opening 230 is formed between the upper half of the first curved plates 221 and the upper part of the short board frame 210.

[0041] Specifically, the first limiting groove 212 and the second limiting groove 223 in the present embodiment are both arranged in a semicircular structure and have threads on the surface. 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 board frame 210 and the long board 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 plate 310 is sleeved on both side ends of the first curved plate 221 in the vertical direction, the arc openings of the second curved plate 320 and the third curved plate 330 are both facing away from the first curved plate 221, and the arc length of the third curved plate 330 is smaller than that of the second curved plate 320. When the second curved plate 320 is pushed by a force, it will deform. Since the third curved plate 330 has a larger bend and a smaller arc length, the third curved plate 330 will deform first, and the second curved plate 320 is used to fit the workpiece first.

[0044] In one embodiment, the limiting layer 300 further includes a plurality of positioning tubes 340 , which are spaced apart in the vertical direction on a side of the second arc plate 320 facing the first arc plate 221 , and a third limiting groove 311 is further provided 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-end surface grinder is applied to a feeding system of a double-end surface grinder in any of the above embodiments, comprising the following steps:

[0047] The workpiece is placed between the short plate frame 210 and the long plate frame 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 specifications of the workpiece, thereby clamping the workpiece.

[0049] When the turntable 20 rotates to a suitable position, the insert 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 interval between the limiting layer 300 and the long plate frame 220 when in use, so that the limiting layer 300 can clamp and limit the workpiece in cooperation with the short plate frame 210, and then put the workpiece in 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 are always kept 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 the bottom of 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 to perform 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-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.
