Description

Technical Field

[0001] The invention relates to the technical field of polishing, in particular to an automatic sanding belt dividing machine. Background Art

[0002] Abrasive belts are coated abrasives, also known as flexible abrasives. Belt grinding is a composite processing technology that has multiple functions of grinding, lapping, and polishing. It is more flexible and safer than solid abrasive wheels when polishing, with higher precision and lower grinding costs. Belt grinding can process workpieces of various shapes with high surface quality and precision requirements. It can not only process common planes, inner and outer circular surfaces, but also process large or special-shaped parts with high surface quality and precision requirements with extremely high efficiency. The superior grinding performance and flexible process characteristics of the belt determine that it has an extremely wide range of applications. From daily life to all walks of life in industrial production, belt grinding is almost everywhere in all fields. Its diverse application forms and wide range are unmatched by any other processing method.

[0003] In the process of watch processing, it is necessary to grind the watch parts with abrasive belts. However, the existing operation of frequently replacing abrasive belts is generally done manually. It is necessary to manually separate the abrasive belts from the original closed annular abrasive belt bundle and then install the separated abrasive belts on the abrasive belt machine. However, the operation efficiency is not high, which is not conducive to the automated management of the processing and production process. Summary of the invention

[0004] In view of the deficiencies in the above-mentioned technologies, the present invention provides an automatic sanding belt separating machine, which can realize automatic separation of sanding belts. The operation is simple and conducive to automated production management. The device has a simple structure and good use effect.

[0005] To achieve the above object, the present invention is achieved as follows:

[0006] An automatic belt-splitting machine, characterized in that it comprises a base, a clamping mechanism, two tensioning wheel mechanisms and two lifting mechanisms, wherein the tensioning wheel mechanisms for tightening the belt are arranged on both sides of the upper end of the base, the clamping mechanism is arranged at the lower part of the base, the two tensioning wheel mechanisms and one clamping mechanism are arranged in an inverted triangle, the belt bundle is suspended in the two tensioning wheel mechanisms and one clamping mechanism and is supported by them, and the two lifting mechanisms are arranged side by side on the top of the base and are adapted to the distance between the two tensioning wheel mechanisms;

[0007] The two lifting mechanisms lift the outermost layer of the abrasive belt of the abrasive belt bundle, and the tensioning wheel mechanisms on the left and right sides rotate synchronously outward to straighten the outermost layer of the abrasive belt, so that the outermost layer of the abrasive belt located between the two tensioning wheel mechanisms is separated, and then the separated abrasive belts are clamped by an external device and sent to a designated work position.

[0008] Furthermore, each lifting mechanism includes an X-axis moving assembly, a Y-axis moving assembly and a manipulator, wherein the X-axis moving assembly is arranged on the top of the base, the Y-axis moving assembly is arranged on the X-axis moving assembly, and the Y-axis moving assembly is movably connected to the X-axis moving assembly; the manipulator is arranged on the Y-axis moving assembly, and the manipulator is movably connected to the Y-axis moving assembly, and the X-axis moving assembly drives the Y-axis moving assembly and the manipulator to move along the X-axis direction. The initial positions of the two manipulators are both located in the middle of the base, and the two Y-axis moving assemblies respectively drive the two manipulators to move forward along the Y-axis direction to lift the outermost layer of the sanding belt, and the X-axis moving assembly drives the two manipulators to move outward along the X-axis direction respectively, and at the same time, the tensioning wheel mechanism rotates outward respectively to straighten and separate the outermost layer of the sanding belt.

[0009] Furthermore, the manipulator includes a push rod that is convenient for inserting into the abrasive belt bundle. The manipulator is set in the form of a push rod, which has a simple structure and is convenient for inserting the push rod into the abrasive belt bundle to separate the abrasive belts layer by layer. It is also beneficial for the external device to grab the separated abrasive belts without being affected by other resistances.

[0010] Furthermore, each X-axis moving assembly includes two linear cylinders, which are symmetrically distributed on the base, and the Y-axis moving assembly is fixed on the slider of the linear cylinder, and the slider of the linear cylinder drives the Y-axis moving assembly and the manipulator to move left and right along the X-axis direction. Among them, the linear cylinder belongs to the prior art, and its specific structure is not described in detail here. The two linear cylinders are connected head to tail and arranged side by side, and are at least adapted to the spacing distance of the two tensioning wheel mechanisms. The two linear cylinders simultaneously drive the two manipulators to perform reciprocating linear motion within a longer distance to achieve the approach or separation of the manipulators.

[0011] Furthermore, the Y-axis moving assembly includes a telescopic cylinder that enables the manipulator to reciprocate forward and backward, and the telescopic cylinder includes one of a piston cylinder, a plunger cylinder, or a film cylinder. Among them, the telescopic cylinder belongs to the prior art, as long as the cylinder can drive the manipulator to reciprocate in the Y-axis direction for a short distance. In addition, the manipulator only moves in and out in the Y-axis direction, and the movement distance is short. The Y-axis moving assembly adopts a cylinder form to simplify the structure of the device.

[0012] Furthermore, each tensioning wheel mechanism includes a tensioning wheel, a rotating cylinder, a support rod and a support cylinder. The rotating cylinder is connected to the tensioning wheel and drives the tensioning wheel to rotate. The support rod is connected to the support cylinder and drives the support rod to move up and down. The tensioning wheel is arranged above the support rod. The support rod is adapted to the tensioning wheel. The sanding belt bundle is suspended on the support rod and clamped by the tensioning wheel. The sanding belt bundle is suspended on the support rod. The support cylinder is used to adjust the distance between the support rod and the tensioning wheel so that the tensioning wheel contacts the outermost sanding belt. When the two tensioning wheels of the device rotate outward, the outermost sanding belt is stretched and straightened by the tensioning wheel under the action of friction, so as to realize the separation operation of the sanding belt. Since the sanding belt bundle will be continuously consumed during the separation process, the thickness of the sanding belt bundle will be continuously reduced. The support cylinder can be used to control the distance between the support rod and the tensioning wheel in real time to ensure that the outermost sanding belt contacts the tensioning wheel.

[0013] Furthermore, the clamping mechanism includes a bracket, a clamping claw and a clamping cylinder, the bracket is fixed on the base, the abrasive belt bundle is clamped in the clamping claw, the clamping claw and the clamping cylinder are drivingly connected, and the clamping cylinder drives the clamping claw to move up and down. In the process of separating the abrasive belts, the abrasive belt bundle is consumed. In order to make the tensioning wheel always keep in contact with the outermost abrasive belt, the support rod will move upward, and because the abrasive belt bundle is an annular closed shape, the length of its circumference is also a fixed value. The clamping cylinder is used to synchronously raise the clamping claw to a certain position, which can effectively prevent the abrasive belt from being damaged.

[0014] Furthermore, the clamping claw includes a clamping plate and four clamping columns, the clamping plate is connected to the clamping cylinder, the four clamping columns are respectively arranged at the four corners of the clamping plate, the clamping columns are fixedly connected to the clamping plate, the abrasive belt bundle is clamped between two clamping columns on the same side, and the distance between the two clamping columns on the same side is greater than the thickness of the abrasive belt bundle. The two support rods and the clamping claw are distributed in an inverted triangle, the clamping claw clamps and supports the naturally drooping part of the abrasive belt bundle, and the inner circle of the abrasive belt bundle is in contact with the support rod and the clamping claw. Since the inner circle of the abrasive belt bundle is actually abutted against the two clamping columns at the upper end of the clamping claw, the two abutting columns at the bottom do not contact the abrasive belt bundle, and they do not affect the separation operation of the abrasive belt.

[0015] Furthermore, the automatic belt separation machine includes a photoelectric sensor for detecting the belt, and the photoelectric sensor is arranged on the tensioning wheel mechanism. The photoelectric sensor belongs to the prior art. In actual application, the photoelectric sensor is connected to the control center of the device and detects whether there is any belt placed on the device. If the belt has been completely separated, a signal is sent to the control center in time to prompt the placement of a new belt bundle.

[0016] The advantages of the present invention are that the tensioning wheel mechanism and the lifting mechanism of the device can realize automatic separation of the abrasive belt, the operation is simple, and the automated production management is convenient; the device has a simple structure and good use effect.
