Description

Technical Field

[0001] The utility model relates to the field of blade trays, and specifically, to a peripheral grinding blade placement tray. Background Art

[0002] The emergence of superhard tools represented by CBN tools is representative of high-speed cutting and high-efficiency machining. Compared with traditional cemented carbide tools, it has very high hardness and wear resistance, shows red hardness and thermochemical stability at high cutting temperatures, etc., and is more suitable for advanced machining methods such as high-speed and dry cutting and "turning instead of grinding". Currently, it has also been widely used in metal processing in various industries. During the manufacturing process of CBN superhard tools, processes such as surface grinding, double-sided grinding, peripheral grinding, precision grinding, and passivation are required. Among them, peripheral grinding is the most important process in the entire CBN superhard tool processing. Its characteristics are automatic loading and unloading by a manipulator, realizing full automation, being suitable for batch production, with high machining accuracy and good consistency of processed products. However, there are many preparatory works before peripheral grinding, and the tray is particularly important. The selection of the tray affects the grasping accuracy of the manipulator, enables full-automatic machining, and machining efficiency. However, existing peripheral grinding trays have defects such as deformation and small support contact surfaces, which affect the clamping operation, and due to size limitations, the number of blades that can be placed is limited.

[0003] The utility model patent with the authorization announcement number CN217596912U discloses an integral tool tray fixture, including a loading plate, a unloading plate, and a connecting component. The loading plate and the unloading plate are installed and matched through the connecting component. A counterbore positioning hole is opened on the upper surface of the unloading plate, and a lower through hole that can pass through the shank of the integral tool is opened at the center position of the counterbore positioning hole. An upper through hole corresponding to the lower through hole and capable of passing through the shank of the integral tool installed by the integral tool tray fixture is opened on the loading plate. An elastic fastener is installed in the counterbore positioning hole. This integral tool tray fixture has advantages such as simple and compact structure, being able to be used in multiple processes and improving production efficiency, but the integral tool tray fixture is not suitable for placing sheet-shaped CBN tools. Content of the Utility Model

[0004] In order to reduce the deformation of the tray and increase the contact area between the sheet-shaped blade and the tray, the technical solution adopted by the utility model is: a peripheral grinding blade placement tray, including a tray base body. A plurality of tip relief grooves with a funnel-shaped cross-section are opened on the tray base body along the length direction. A plurality of partition placement grooves for separating the tip relief grooves are opened on the tray base body along the width direction. A partition strip is movably arranged in the partition placement groove;

[0005] Two adjacent partition strips and the two inclined walls at the top of the tip relief groove enclose to form a placement space for accommodating peripheral grinding blades.

[0006] Based on the above, in order to stably support the peripheral grinding blade and increase the support contact surface, the partition placing groove is vertically arranged with the tool tip relief groove.

[0007] Based on the above, in order to facilitate the manipulator to pick up the peripheral grinding blade, multiple tool tip relief grooves are arranged at equal intervals.

[0008] Based on the above, in order to facilitate the manipulator to pick up the peripheral grinding blade, multiple partition placing grooves are arranged at equal intervals.

[0009] Based on the above, the depth value of the partition placing groove is less than or equal to the depth value of the tool tip relief groove.

[0010] Based on the above, the separating strip is made of bakelite or acrylic strip.

[0011] Based on the above, in order to carry out stable support, when the separating strip is placed in the partition placing groove, the top of the separating strip is set to be higher than the upper surface of the tray base body.

[0012] Based on the above, the two ends of the separating strip are provided with arc transitions.

[0013] The utility model has substantial characteristics and progress compared with the prior art. Specifically, the peripheral grinding blade placing tray provided by the utility model adopts bakelite material or acrylic material, and slots are opened on the whole plate according to the blade shape, so that the peripheral grinding blade placing tray forms an integral molding structure. The overall tray is not easy to deform after long-term use. At the same time, the tray angle is designed to be the same as the blade angle. When placing the blade, both sides of the lower side of the blade can contact the side wall of the tray slot, thereby increasing the contact area between the blade and the tray and making the placement position of each blade the same.

[0014] Specifically, the tray angle, that is, the included angle between the two inclined walls at the top of the tool tip relief groove, can be set to 35 degrees, 55 degrees, 60 degrees, 80 degrees, 90 degrees according to production needs.

[0015] Furthermore, the tool tip relief grooves are separated by bakelite strips or acrylic strips, which ensures that the distance between the blades is consistent. The tray is designed to be rectangular, increasing the length, so that the number of blades placed is more than twice that of the original tray. BRIEF DESCRIPTION OF THE DRAWINGS
