Abstract
Description
Technical Field
[0001] This utility model relates to a tooling fixture structure for a grinding wheel machine used for machining lens concave and convex mold cores. Background Technology
[0002] Currently, the Y-axis grating ruler accuracy of existing mold core processing machines is 2nm, while the X-axis grating ruler accuracy is 0.1nm. This results in unstable surface shapes, meaning that the grating ruler accuracy errors on the X and Y axes are relatively large. This leads to the dimensional accuracy of the processing and inspection exceeding the design requirements, thus affecting processing efficiency. As the precision requirements for glass lenses become increasingly stringent, the Y-axis precision of the machine tool is limited and cannot meet the processing requirements. Therefore, the X-axis is used directly for processing by changing the 45° inclined axis and 90° vertical tooling fixtures, eliminating the need to use the Y-axis of the machine tool. This method can meet the precision and processing requirements of glass lenses. However, when processing concave and convex mold cores, it is necessary to switch fixtures back and forth and repeatedly clamp and calibrate, wasting a lot of time on fixture changes and calibration, which seriously slows down production efficiency. Utility Model Content
[0003] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and provide a grinding wheel tooling fixture structure for processing lens concave and convex mold cores. The design is reasonable, and the tooling adjustment plate and tooling inclined block can quickly switch the inclined axis to 45° and vertical 90°, solving the problem that a lot of time is wasted on tooling calibration when changing tooling fixtures. This facilitates specialized production and improves production efficiency.
[0004] This utility model is achieved by the following solution: a tooling fixture structure for a grinding wheel machine for processing lens concave and convex mold cores: including a tooling adjustment plate, a tooling inclined block is rotatably connected to the front side of the tooling adjustment plate, and a grinding wheel machine is installed on the tooling inclined block.
[0005] Furthermore, the tooling adjustment plate includes an adjustment plate, and an adjustment block is installed on the front side of the adjustment plate.
[0006] Furthermore, a clearance groove is provided on the rear side of the tooling inclined block corresponding to the adjustment block, and the adjustment block is rotatably connected in the clearance groove.
[0007] Furthermore, the adjusting block is a right-angled triangular block, with one end face of the adjusting block corresponding to one right-angled side vertically fixed to the adjusting plate, and the end face corresponding to the other right-angled side horizontally set. The tooling slope block is a right-angled triangular block, and the clearance groove is opened in the middle of the edge corresponding to the right-angled end of the tooling slope block.
[0008] Furthermore, the lower acute-angle end of the adjusting block is provided with a rounded chamfer, and a fixing hole that passes through the adjusting block is provided laterally inside the lower acute-angle end of the adjusting block. The groove wall of the relief groove is provided with connecting holes at both ends corresponding to the fixing hole. The connecting holes pass through the groove wall of the relief groove, and the fixing holes and connecting holes are connected by a pin.
[0009] Furthermore, the center of the chamfered arc of the adjusting block is the same as the center of the fixing hole.
[0010] Furthermore, on one triangular end face of the adjusting block, two positioning holes are formed around the fixed hole, with the central angle between the two positioning holes being 45 degrees. On the triangular end face of the tooling inclined block, a pin hole that mates with the positioning hole is formed inside the right angle, and the pin hole and the positioning hole are connected by a positioning pin.
[0011] Furthermore, it also includes a tooling fixing plate, which is fixedly connected to the adjusting plate by a pin.

Detailed Implementation
[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.
[0024] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0025] like Figures 1-6 As shown, a tooling fixture structure for a grinding wheel machine for processing lens concave and convex mold cores includes a tooling adjustment plate 1, a tooling inclined block 2 rotatably connected to the front side of the tooling adjustment plate, and a grinding wheel 3 mounted on the tooling inclined block. In use, by rotating the tooling inclined block and fixing it at the required angle, the angle of the grinding wheel is fixed, thereby fixing the position of the grinding wheel machine for processing the mold cores.
[0026] In this embodiment, the specific connection method between the tooling adjustment plate and the tooling inclined block is as follows: the tooling adjustment plate includes an adjustment plate 4, an adjustment block 5 is installed on the front side of the adjustment plate, and a clearance groove 6 is opened on the rear side of the tooling inclined block corresponding to the adjustment block. The adjustment block is rotatably connected in the clearance groove. The rotatable connection method can be the existing shaft type, and other forms are also possible, as long as a rotatable connection can be achieved. More specifically, the adjustment block is a right-angled triangular block, and the end face corresponding to one of the right-angled sides of the adjustment block is vertically fixed to the adjustment plate. On the section plate, the end face corresponding to the other right-angled side is horizontally set. The tooling inclined block is a right-angled triangular block. The relief groove is opened in the middle of the edge corresponding to the right-angled end of the tooling inclined block, that is, the adjustment plate is vertically set. One of the two end faces corresponding to the two right-angled sides of the adjustment block is horizontally set and the other is vertically set. The vertically set end face is fixed on the adjustment plate, and the horizontally set end face is at the bottom. The inclined surface corresponding to the inclined side of the adjustment block is on the front side. The relief groove corresponds to the triangular adjustment block. Of course, other shapes are also possible, as long as rotational connection can be achieved.
[0027] In this embodiment, to specifically realize the rotatable connection between the adjusting block and the tooling inclined block, the lower acute-angle end of the adjusting block is provided with a rounded chamfer 7, that is, the acute-angle end at the front end is rounded. A horizontal fixing hole 8 is provided in the lower acute-angle end of the adjusting block, which passes through the adjusting block. The center of the rounded chamfer of the adjusting block is the same as the center of the fixing hole. That is, in order to facilitate the rotation of the tooling inclined block, the tooling inclined block can rotate around the rounded chamfer. The groove wall of the relief groove is provided with connecting holes 9 at both ends corresponding to the fixing holes. The connecting holes pass through the groove wall of the relief groove. The fixing holes and the connecting holes are connected and connected by a pin. The pin can be an existing rotating shaft or other mechanism used to realize the function of a rotating shaft in a rotatable connection, as long as it can achieve rotation.
[0028] In this embodiment, to enable the tooling inclined block to switch between an inclined axis of 45° and a vertical angle of 90°, two positioning holes 10 are formed on one triangular end face of the adjusting block, with the fixing hole as the center. These positioning holes can be horizontally penetrating the adjusting block, and the central angle between the two positioning holes is 45°, meaning the line connecting the centers of the two positioning holes to the center of the fixing hole forms a 45° angle. Since the adjusting block is a right-angled triangle, one positioning hole can be inside the right-angled end of the adjusting block, and the other positioning hole can be near the inclined side of the adjusting block. A pin hole 11, which mates with a positioning hole, is provided inside the right angle on the angular end face. The pin hole and the positioning hole are connected by a positioning pin. That is, in the 45° inclined axis state, the pin hole is connected to the positioning hole inside the right angle end of the adjusting block, so that one of the two end faces corresponding to the two right angle sides of the tooling inclined block is set horizontally and the other is set vertically, with the horizontal end face facing down. At this time, the inclined surface of the tooling inclined block is set at 45°, which facilitates the 45° inclined axis installation of the grinding wheel. In the 90° vertical state, the pin hole is connected to the positioning hole near the inclined side of the adjusting block. This flips the inclined surface of the tooling inclined block from the original 45° to 90°, which facilitates the 90° vertical installation of the grinding wheel.
[0029] In this embodiment, in order to realize the installation of the overall fixture, a tooling fixing plate 12 is also included. The tooling fixing plate and the adjusting plate are fixedly connected by a pin. The rear side of the tooling fixing plate is provided with a number of mounting holes that cooperate with the mold core processing machine table for installation.
[0030] In this embodiment, for the sake of reasonable design, there is a movable gap 13 between the side of the tooling inclined block corresponding to the adjustment plate and the adjustment plate. That is, when the inclined axis is 45°, there is a movable gap between the vertical right-angle end face of the tooling inclined block and the adjustment plate to avoid interference when the angle is flipped. At the same time, the right-angle end of the tooling inclined block is a rounded chamfer 14.
[0031] In this embodiment, for the sake of reasonable design, the grinding wheel is fixed to the end face corresponding to the inclined edge of the tooling slant block by bolts, and the direction of the grinding wheel spindle is parallel to the direction of the inclined edge of the tooling slant block.
