[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0036] In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides various specific examples of processes and materials, but those of ordinary skill in the art may recognize the application of other processes and / or the use of other materials.

[0037] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0038] In the process of machining sintered grinding wheels by spark machine, it is necessary to fix the sintered grinding wheels by clamping jigs, and cooperate with the machining electrodes configured on the spark machine to machine holes and grooves at the corresponding positions on the sintered grinding wheels. In order to adapt to the cylindrical structure of the sintered grinding wheel, a special clamp is usually configured to clamp a sintered grinding wheel at a time, and cooperate with the motor on the spark machine to realize hole and groove machining; however, only one sintered grinding wheel can be machined at a time, which greatly limits the production efficiency of the grinding wheel.

[0039] Therefore, the embodiment of the present application provides an electrospark batch grooving jig for sintered grinding wheels, which aims to improve the efficiency of batch processing of holes and grooves on sintered grinding wheels to a certain extent.

[0040] See also Figure 1 and Figure 2 In some embodiments, the EDM batch grooving jig for the sintered grinding wheel may include: a base 100, a clamping bracket 200 and a clamping piece 300; the clamping bracket 200 is connected to the base 100, and the clamping piece 300 is connected to the clamping bracket 200, so as to clamp the sintered grinding wheel 400 placed on the base through the clamping piece 300.

[0041] Specifically, the base 100 is the foundation of the entire grooving jig, which is used to install other components and carry the sintered grinding wheel 400 to be processed; a plurality of limiting grooves 111 are provided on the base 100 to accommodate and fix a plurality of sintered grinding wheels 400, so that a plurality of sintered grinding wheels 400 can be processed simultaneously during mass production, which helps to improve the efficiency of mass production.

[0042] The clamping bracket 200 is the installation structure of the clamping member 300 and can be arranged on the base 100 to support the installation of the clamping member 300. Correspondingly, an installation base 210 can be opened on the clamping bracket 200 as a structure adapted to install the clamping member 300.

[0043] The clamping member 300 is used to match and clamp the multiple sintered grinding wheels 400, and the clamping member 300 can be installed on the clamping bracket 200 through the mounting base 210; usually, the clamping member 300 can be aligned with the multiple limiting grooves 111 to press the sintered grinding wheels 400 into the limiting grooves 111, so that during mass production, multiple sintered grinding wheels 400 can be clamped at the same time, and then cooperate with the electrodes configured on the spark machine to synchronously process multiple sintered grinding wheels 400, thereby improving the efficiency of mass production as a whole.

[0044] When processing the hole groove structure on the sintered grinding wheel 400, the positions of the spark machine electrode and the multiple sintered grinding wheels 400 are properly arranged so that the electrode can discharge stably, and the electric spark acts on the multiple sintered grinding wheels 400 to form the hole groove structure.

[0045] See also Figure 2 In some embodiments, considering that debris may appear during the grooving process of the sintered grinding wheel 400, in order to prevent the accumulation of debris from affecting the grooving quality, a chip removal groove 112 may be provided at the bottom of the limiting groove 111 to discharge the debris.

[0046] In some embodiments, considering that the sintered grinding wheel 400 is mostly a cylindrical part, in order to take into account both the accommodation limiting capacity and the adaptability to various specifications of products, the limiting groove 111 can be set to a V-shaped groove, so that it can accommodate a cylindrical sintered grinding wheel 400 within a certain specification range and have better adaptability.

[0047] In some embodiments, the plurality of limiting grooves 111 may be divided into a plurality of groups according to the specifications that can be accommodated, so as to further expand the range of product specifications that can be accommodated, so as to further improve the scope of application.

[0048] Generally speaking, the parameters such as the depth specification and the width specification of the limiting groove 111 can be used as the grouping standard and principle.

[0049] In some embodiments, the limiting groove 111 may also be in other shapes, such as polygonal, arc-shaped, etc.

[0050] See also Figure 3 In some embodiments, in order to make full use of the base 100 and expand the range of product specifications that can be accommodated, the base 100 can be set as a block member 110, and the multiple limiting grooves 111 are set on the peripheral surface 114 of the block member 110, so that more limiting grooves 111 can be accommodated, and more specifications of the limiting grooves 111 can be set, thereby fully improving the bearing capacity and application range of the base 100.

[0051] The middle area of ​​the block 110 may be further utilized to open a clamping hole 113 as a structure for fixing and installing the block 110 to other fixed structures or foundations.

[0052] For example, the clamping hole 113 can be used to sleeve onto a support rod, support arm or other structure, and then fixed by a locking member.

[0053] See also Figure 1 and Figure 2 In some embodiments, the mounting base 210 may include a countersunk hole 211 and a baffle 212 .

[0054] The countersunk hole 211 can be opened on the clamping bracket 200, the baffle 212 is arranged on the clamping bracket 200, the clamping member 300 is movably inserted into the countersunk hole 211, and the clamping member 300 elastically abuts against the baffle 212 and can be elastically moved to elastically clamp the sintered grinding wheel 400.

[0055] That is, the pressing member 300 can use the counterbore 211 to constrain its moving direction, keep pressing the sintered grinding wheel 400 in the limiting groove 111, and apply elastic pressing force to the sintered grinding wheel 400 based on the baffle 212.

[0056] In some embodiments, the pressing member 300 may include a push rod 310 and an elastic member 320 .

[0057] The push rod 310 is inserted into the counterbore 211 and can move along the counterbore 211 to adapt to abut against the sintered grinding wheel 400 to achieve a clamping operation; at the same time, a radial flange 311 is provided on the rod body of the push rod 310, and the diameter of the radial flange 311 is larger than the inner diameter of the second section hole 211b of the counterbore 211 and smaller than the inner diameter of the first section hole 211a, so that the radial flange 311 can be accommodated in the first section hole 211a and stopped by the hole end face 211c of the second section hole 211b, thereby limiting the push rod 310 from being separated from the counterbore 211 and ensuring the stability of its functional structure.

[0058] In coordination, the elastic member 320 abuts between the radial flange 311 and the baffle 212, so as to push the push rod 310 toward the sintered grinding wheel 400 based on the baffle 212, thereby pressing the sintered grinding wheel 400; accordingly, the elastic member 320 should be stably arranged between the radial flange 311 and the baffle 212, and when the push rod 310 approaches the baffle 212 to a certain extent, the elastic member 320 can be compressed, so that the push rod 310 has a certain pressing force. Of course, the initial form of the elastic member 320 can also be set to a compressed state, which has a certain elastic pressure at the beginning, so that the push rod 310 can be kept in a compressed state, avoiding its random shaking to affect the convenience of operation and reduce the risk of scratching the sintered grinding wheel 400.

[0059] See also Figure 2 and Figure 5 In some embodiments, in order to improve the moving posture of the push rod 310 under the action of the elastic member 320, a through hole 212a may be opened on the baffle 212, and the tail rod body of the push rod 310 may be slidably inserted into the through hole 212a, so that the push rod 310 can move stably along its axial direction, maintain the stability of the clamping position of the sintered grinding wheel 400, and ensure the clamping state.

[0060] See also Figure 6 In some embodiments, in order to improve the operational convenience of the push rod 310, a holding portion 312 may be provided at the tail end of the push rod 310, so that the push rod 310 can be pulled back by the holding portion 312 to leave space for installing the sintered grinding wheel 400, and then the holding portion 312 can be released so that the push rod 310 can be naturally ejected under the action of the elastic member 320 to press the sintered grinding wheel 400.

[0061] Generally speaking, the holding portion 312 can be configured as a disc, a round head, or other shapes that are convenient for holding.

[0062] See also Figure 2 and Figure 6 In some embodiments, the elastic member 320 may include a compression spring 321, which is sleeved on the rod body of the push rod 310, and the two ends of the compression spring 321 are respectively abutted against the radial flange 311 and the baffle 212.

[0063] See also Figure 6 In some embodiments, an inward groove 313 may be provided at one end of the push rod 310 close to the sintered grinding wheel 400 to reduce the contact area between the end of the push rod 313 and the sintered grinding wheel 400, maintain the contact pressure, and improve the clamping effect.

[0064] See also Figure 2 , Figure 3 and Figure 4 In some embodiments, the clamping bracket 200 may be a portal bracket, the countersunk hole 211 is opened on the top of the portal bracket, and the baffle 212 may be fastened to the clamping bracket 200 by bolts.

[0065] Similarly, the clamping bracket 200 can also be fastened to the base 100 by bolts, that is, a screw groove 115 can be opened on the block 110, and a corresponding screw hole 220 can be opened on the clamping bracket 200 to install the fastening bolts.
