In addition, an automatic honing measurement device used in the conventional lens honing device is (2) 1232147 Japanese Patent Application Laid-Open No. 59-93262 disclosed by the applicant of the present application. This conventional invention relates to a lens honing machine, and more particularly to a honing mechanism of a small and medium diameter precision spherical lens, which is configured to rotate the honing disc built in the center of the box while making the whole box A honing disc rotating and swinging mechanism (A) swinging in a pendulum shape, and a lens honing mechanism constituted by a honing support fixing and pressing mechanism (B) connected to the honing disc on the honing disc and pressurized by a spring through a spring shaft Install a grounding measurement terminal with an electrical contact micrometer on the honing bracket fixing and pressurizing mechanism (B), fix the measurement terminal to the bracket shaft through a detection plate connected with an adjustment bolt, and meanwhile, fix the above through a mounting plate. An automatic honing measuring device with an electric contact micrometer fixed on the support arm. Specifically, as shown in FIG. 7, it is a micrometer mounted on a honing stand fixed pressure mechanism of a conventional device, and 62 is an electric contact of the main body. The micrometer 62 is configured to operate an electrical contact via a signal extraction lead wire, and is grounded to a measurement terminal mounted above. According to the above configuration, the honing measuring device is required to set the scale of the micrometer 62 to move the needle to the scale position adjusted by the pressing action of the measuring terminal to issue a stop signal. In addition, as a conventional spherical surface processing device, there is an invention disclosed in Japanese Patent Laid-Open No. Sho 59-93 262 disclosed by the applicant of the present invention. This conventionally known device is designed to process workpieces such as lenses with high accuracy and smoothness, and its mechanism is to set a pressurizing shaft that presses the workpiece L with a bracket on the shaft that passes through the center of the sphere 0 of the spherical surface of the tool disc. On the line, at the same time, the swinging body which can freely rotate and support the tool plate is formed with a spherical surface centered on the tool plate's spherical surface as a spherical center, and a guiding surface portion is provided with a (3) 1232147 supporting member which can swing and support the swinging body freely The swing motor swings the swing body and the center of the swing swings the tool disc.

[Summary of the Invention] [Problems Solved by the Invention] However, in the conventional lens honing device (Japanese Patent Sho Sho 4 3-1 3 4 3 9), it is necessary to adjust the swing center angle of the elastic fixing screw to perform rapid Difficult to adjust. In addition, in the conventional automatic honing measurement device (Japanese Patent Application Laid-Open No. Sho 59-93 262), when the tool tray is deep in structure, it is not possible to measure and remove the lens only when the swing angle is deep, but it is necessary to set the swing angle Detect the lens to stop the swing to remove the lens, so even if you input the cutting completion signal of (4) 1232147, the cutting cannot be stopped immediately. As a result, cutting will still be performed between the shallow measurement movements of the swing angle, especially when the swing speed is slow, which will cause the thickness of the cut lens to change. Especially in spherical processing equipment (Japanese Patent Application Laid-Open No. 7-205 008), because there is no singularity within one cycle of swing, the machining accuracy can be maintained without causing partial wear of the tool plate, but the tool plate with poor accuracy can be maintained. In the case of continuous machining accuracy, it is difficult to correct the tool disc by using partial wear within one cycle of the swing. Therefore, the present invention is an apparatus developed to solve the above-mentioned problems, and aims at the stability of the machining accuracy that has both the reduction of the operation time and the ease of the tool plate correction. [Means for Solving the Problem] The present invention is made by improving a conventional device in order to solve the above problems. A tool disc having a spherical surface has a function of pressurizing a lens to be processed on an axis passing through a spherical center of the tool disc. The conveying function of the axis moving in parallel has the function of rotatably supporting the tool tray and forming a spherical swingable swing body around the same point as the center of the sphere center of the tool tray. In addition, the swing body is supported on a spherical air shaft. In the lens honing device that makes the spherical air bearing center and the center of the tool disc form the same point, there is provided a lens honing device having the swing body parallel to the rotation surface of the tool disc and passing through the tool disc ball center. On the line, a rotation stopper of the swinging body is provided, and a lens spherical honing device characterized by the use of an arch cam to set the center of the swinging vibration angle is used in the center of the swinging vibration angle adjustment mechanism, and the above-mentioned lens spherical honing device provides a swinging temporary Stop at the position where the thickness of the lens to be added is set to -7- (5) 1232147, and it will be processed. The lens is vacuum-sucked on the lens holder, so that the lens holder is slightly raised from the lens honing tool plate, and moves toward the minimum angle of the swinging angle of the swinging body, and then moves to the lens spherical surface to which the processed lens can be detached. In addition, the above-mentioned lens spherical honing device provides a lens spherical honing device formed by a variable swing speed at a specified position of a swinging period of a swinging body, and the above-mentioned lens spherical honing device provides rough honing of a lens to be processed. Lens spherical honing device for subsequent honing processing of fine honing. [Inventive Embodiment] An embodiment of the present invention has a function of pressing a processed lens on an axis passing through the center of the tool disc's spherical center on a spherical tool disc, and a transport function capable of moving parallel to the axis. The tool disc is supported to rotate freely, and a spherically swingable swing body is formed around the same point of the tool center as the center of the tool disc. The swing body is supported on a spherical air bearing, and the center of the spherical air bearing and the center In the lens honing device in which the spherical center of the tool disc is formed at the same point, a rotation stopper of the swing body is formed on the swing body parallel to the rotation surface of the tool disc and on the line passing through the spherical center of the tool disc. The center adjustment mechanism of the angle uses an arc cam to set the lens spherical honing device which is characterized by swinging the angular center of the vibration, and the above-mentioned lens spherical honing device provides a kind of swing that can temporarily stop at a position where the thickness of the processed lens is set in advance, and will be The processed lens is vacuum-adsorbed on the lens holder, so that the lens holder is slightly raised and penetrated. The lens honing tool plate is detached and moves in the direction of the minimum swing angle of the swinging body -8- (6) 1232147 After moving the lens spherical honing device to the position where the lens to be processed can be detached, and the lens spherical honing The grinding device provides a lens spherical honing device that is configured to form a variable swing speed at a specified position of the swinging body for one cycle, and the lens spherical honing device is used to provide fine honing of the processed lens after rough honing. The processed lens spherical honing device can quickly and delicately set the center of the swing vibration angle when turning the handle of the transport screw provided at the center setting mechanism of the swing vibration angle. At the same time, the cutting can be performed simultaneously with the processing signal. Changes in the thickness of the intermediate wall of the object lens. In addition, since the swing speed can be changed at a specific position in one cycle, it is possible to promote the offset wear of the disc and adjust the tool disc at the same time. In addition, a large-mesh dial can be used for rough honing on the tool tray, and raw materials can be processed in the same device until final honing. Therefore, it is not necessary to use different devices in different steps in the past to simplify work. In particular, the device of the present invention can provide a honing device 5 which has both shortened operation time, stability of processing accuracy, and easy adjustment of accuracy.
