Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, and more specifically, to an automatically calibrated double-end face grinding machine. Background Technology

[0002] A double-end face grinder is a high-precision grinding machine mainly used for simultaneously grinding two parallel end faces of a workpiece to ensure the parallelism, flatness, and dimensional accuracy of the two faces. It is widely used in efficient mass production in industries such as automotive, bearings, hydraulic components, sealing rings, ceramics, and cemented carbide. For example, the double-end face grinder spring mechanism proposed in publication number "CN222903608U" includes a feeding disc, rollers, a receiving disc, and a spring mechanism. The spring mechanism is located on one side of the feeding disc, and the receiving disc is located on the other side. The spring mechanism includes a spring steel plate, a base, and a pressure block. The base is mounted on the grinding machine's mounting plate by fixing bolts. The lower end of the spring steel plate is mounted on a threaded hole B in the base by bolt B. The pressure block is mounted on a threaded hole A in the base by bolt A.

[0003] However, in the above technical solution, after the worker puts the workpiece into the material tray, the above-mentioned feeding mechanism does not have a structure for calibrating and positioning the workpiece. The lack of a calibration structure may cause the distance between the two ends of the workpiece and the two grinding discs of the double-end grinding machine to be inconsistent. The lack of a positioning structure may cause the workpiece to become loose when it is being ground by the grinding discs. The loose workpiece will be displaced under the action of grinding force. Both of these situations may cause one grinding disc to not contact the workpiece, while the other side is over-ground, resulting in uneven workpiece thickness that exceeds the tolerance range. Utility Model Content

[0004] The main objective of this invention is to provide an automatically calibrated double-end face grinder, which can effectively solve the problem in the prior art where, after the operator places the workpiece into the material tray, the feed mechanism lacks a structure for calibrating and positioning the workpiece. The absence of a calibration structure can lead to inconsistent distances between the two ends of the workpiece and the two grinding discs of the double-end face grinder. The lack of a positioning structure can also cause the workpiece to become loose during grinding. This loose workpiece can then shift under the grinding force, potentially resulting in one grinding disc failing to contact the workpiece while the other side is over-ground, leading to uneven workpiece thickness that exceeds tolerances.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An automatically calibrated double-end face grinder includes a machine base, an opposing sliding platform is provided on the upper surface of the machine base, a first motor is fixedly installed on the upper surface of each of the two moving ends of the opposing sliding platform, and a grinding disc is fixedly installed on the output shaft ends of each of the two first motors.

[0007] A bracket is fixedly installed on one side of the base, and a rotating column is rotatably installed between the two sides of the inner wall of the bracket. A feeding wheel is fixedly fitted on the body of the rotating column, and a material groove is opened through one side surface of the feeding wheel. A second motor is fixedly installed on one side of the bracket, and one end of the rotating column passes through the bracket and is fixedly connected to the output shaft end of the second motor.

[0008] The upper surface of the bracket is fixedly mounted with a first guide plate on both sides by a base plate, and a clamping component for clamping the workpiece is provided on one side of the feeding wheel.

[0009] Preferably, the clamping assembly includes an annular groove, which is formed on one side surface of the feeding wheel. The inner wall surface of the annular groove is provided with a plurality of connecting grooves, and one end of each connecting groove is connected to a corresponding material trough.

[0010] An installation ring is fixedly installed on one side of the inner wall of the annular groove. Several sliding rods are slidably arranged through the inner wall of the installation ring. One end of each adjacent sliding rod is fixedly installed with a clamping block, and the other end of each adjacent sliding rod is fixedly installed with an installation block.

[0011] Preferably, a first semi-circular block is fixedly installed on one side of each of the mounting blocks;

[0012] A plurality of connecting rods are slidably disposed through one side surface of the inner wall of the annular groove. A connecting block is fixedly installed at one end of adjacent connecting rods. A second semicircular block is fixedly installed on one side of each connecting block. A support column is fixedly installed on one side of the inner wall of the bracket. A third semicircular block is fixedly installed at one end of the support column.

[0013] The other end of the adjacent connecting rod is fixedly installed with a second guide plate.

[0014] Preferably, each of the slide bars is fitted with a first spring on the side near the corresponding mounting block.

[0015] Preferably, each of the connecting rods is fitted with a second spring on the side of its body closest to the corresponding connecting block.

[0016] Preferably, each of the feed troughs is provided with a rubber sleeve.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) During the process of entering the processing area, the workpiece is gradually aligned into the material groove under the guidance of the inclined surfaces and planes of the two first guide plates. After the workpiece enters the processing area, the third semicircular block pushes the corresponding second semicircular block, causing the connecting rod to move the second guide plate. Under the pushing action of the inclined surfaces of the second guide plate, the first semicircular block can drive the sliding rod and the clamping block to move, so that the clamping block passes through the connecting groove and clamps the outer wall of the workpiece, so that the workpiece is positioned inside the material groove, avoiding loosening during grinding, thereby avoiding the situation where the workpiece position is not calibrated and positioned, which may cause one side of the grinding disc to not contact the workpiece, while the other side is ground excessively.

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0027] like Figures 1-6 As shown, an automatically calibrated double-end face grinder includes a base 1, an opposing sliding platform 2 is provided on the upper surface of the base 1, a first motor 3 is fixedly installed on the upper surface of the two moving ends of the opposing sliding platform 2, and a grinding disc 4 is fixedly installed on the output shaft ends of the two first motors 3.

[0028] A bracket 5 is fixedly installed on one side of the base 1. A rotating column 6 is rotatably installed between the two sides of the inner wall of the bracket 5. A feeding wheel 7 is fixedly fitted on the body of the rotating column 6. A material groove 8 is opened through one side of the feeding wheel 7. A second motor 9 is fixedly installed on one side of the bracket 5. One end of the rotating column 6 passes through the bracket 5 and is fixedly connected to the output shaft end of the second motor 9.

[0029] The first guide plate 11 is fixedly installed on both sides of the upper surface of the bracket 5 via the base plate 10, and a clamping component 12 for clamping the workpiece is provided on one side of the feeding wheel 7.

[0030] The clamping assembly 12 includes an annular groove 1201, which is formed on one side surface of the feeding wheel 7. The inner wall surface of the annular groove 1201 is provided with a plurality of connecting grooves 1202, and one end of each connecting groove 1202 is connected to the corresponding material trough 8.

[0031] An installation ring 1203 is fixedly installed on one side of the inner wall of the annular groove 1201. Several sliding rods 1204 are slidably arranged through the inner wall of the installation ring 1203. One end of adjacent sliding rods 1204 is fixedly installed with a clamping block 1205, and the other end of adjacent sliding rods 1204 is fixedly installed with an installation block 1206.

[0032] A first semicircular block 13 is fixedly installed on one side of each mounting block 1206;

[0033] A number of connecting rods 14 are slidably arranged through one side of the inner wall of the annular groove 1201. A connecting block 15 is fixedly installed at one end of adjacent connecting rods 14. A second semicircular block 16 is fixedly installed on one side of each connecting block 15. A support column 17 is fixedly installed on one side of the inner wall of the bracket 5. A third semicircular block 18 is fixedly installed at one end of the support column 17.

[0034] The other end of the adjacent connecting rod 14 is fixedly installed with a second guide plate 19.

[0035] Each slide bar 1204 is fitted with a first spring 20 on the side near the corresponding mounting block 1206.

[0036] Each connecting rod 14 has a second spring 21 fitted on the side of its body closest to the corresponding connecting block 15.

[0037] The worker places the workpiece in the material groove 8 of the feeding wheel 7, and then starts the second motor 9, causing its output shaft to drive the rotating column 6 to rotate. The rotating column 6 then drives the feeding wheel 7 to rotate, and the workpiece enters the processing area as the feeding wheel 7 rotates. During the process of entering the processing area, the workpiece is gradually centered in the material groove 8 under the guidance of the inclined surfaces and the plane of the two first guide plates 11. After the workpiece enters the processing area, the third semicircular block 18 pushes the corresponding second semicircular block 16, causing the connecting rod 14 to drive the second guide plate 19 to move. Under the pushing action of the inclined surface of the second guide plate 19, the first semicircular block 13 can drive the sliding rod 1204 and the clamping block 1205 to move, so that the clamping block 1205 passes through the connecting groove 1202 and clamps the outer wall of the workpiece, so that the workpiece is positioned inside the material groove 8, preventing loosening during grinding. This avoids the situation where the workpiece position is not calibrated and positioned, which may cause one side of the grinding wheel 4 to not contact the workpiece, while the other side is over-grinded.

[0038] In another embodiment of this utility model, a rubber sleeve 22 is provided in each material trough 8.

[0039] The friction generated when the inner wall of the rubber sleeve 22 is in contact with the outer wall of the workpiece can prevent the workpiece from tilting due to external force after it is aligned by the first guide plate 11 and during the process of the clamping block 1205 clamping the workpiece.

[0040] The working principle of this type of automatically calibrated double-end face grinder:

[0041] In use, the operator places the workpiece in the material groove 8 of the feeding wheel 7, and then starts the second motor 9, causing its output shaft to drive the rotating column 6 to rotate. This allows the rotating column 6 to drive the feeding wheel 7 to rotate, and the workpiece enters the processing area as the feeding wheel 7 rotates. During the process of entering the processing area, the workpiece is gradually aligned into the material groove 8 under the guidance of the inclined surfaces and flat surfaces of the two first guide plates 11. After the workpiece enters the processing area, the third semicircular block 18 pushes the corresponding second semicircular block 16, causing the connecting rod 14 to drive the second guide plate 19 to move. Under the pushing action of the inclined surfaces of the second guide plate 19, the first semicircular block 13 can drive the sliding rod 1204 and the clamping block 1205 to move, so that the clamping block 1205 passes through the connecting groove 1202 and clamps the outer wall of the workpiece, thus positioning the workpiece inside the material groove 8 and preventing loosening during grinding. This avoids the situation where the workpiece position is not calibrated and positioned, which may result in one side of the grinding wheel 4 not contacting the workpiece while the other side is over-grinded.

[0042] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
