This processing method has serious material loss, only half of the material can be effectively utilized, the production material cost is too high; moreover, the material flat grinding processing time is relatively long, the production efficiency is low, and the production demand cannot be met; the material bonding on the machine has the risk of material collision, increasing the hidden production cost investment; the material flat grinding to the center line height is not easy to control, and there is a risk of material scrap and non-use. Chinese patent application No. 2023230838991 discloses a double-sided grinding device for quartz preform rod processing, which can realize one machine with multiple functions, can be polished, drilled and milled, eliminate the polishing taper of the round rod, improve the parallelism of the polygonal rod, and can be used for polishing various special-shaped rods. Although it can also achieve the polishing processing of the semi-circular quartz rod, the material loss is serious and the work efficiency is low. SUMMARY

[0006] Through the setting of the round rod processing jig, the half-cutting operation of the quartz round rod is facilitated, one round rod is cut in half to form two semi-circular quartz rods, the material utilization rate is high, and compared with the flat grinding processing, the work efficiency is improved and the cost is reduced.

[0007] Preferably, the bottom of the clamping groove is provided with a sunken accommodation groove.

[0008] The accommodation groove provides a space for the cutting line, and after the cutting line cuts the round rod, the cutting line avoids touching the side wall of the clamping groove.

[0009] Preferably, the lower surface of the loading seat is fixedly connected with a fixed block at the middle position.

[0010] The fixing block is arranged on the loading seat, and the loading seat is conveniently connected to the workbench of the cutting machine.

[0011] As preferred, the loading seat is detachably connected with positioning blocks at both ends, the upper surface of the positioning block is provided with a tangent line positioning groove, and the lower surface of the positioning block is provided with a positioning sink.

[0012] Before cutting, the position of the loading seat is adjusted through the tangent line positioning groove on the positioning block and the cutting line, so as to ensure the accuracy of the cutting position.

[0014] The positioning line groove on the positioning seat is provided on the loading seat at both ends, and the positioning line groove positions the cutting line. Before cutting, the cutting line is aligned with the positioning line groove to ensure the accuracy of the cutting position.

The clamping slot is V-shaped, so the axis of the round bar is located on the center plane of the clamping slot. During the cutting process, the bar moves vertically downwards, thus achieving the halving of the round bar. After the round bar is halved, it is heated to remove the glue, and the halved round bar is removed from the mounting base by the edge.

The loading seat moves back and forth so that both ends of the loading seat are respectively aligned and positioned with the two alignment blocks.

[0024] Before installing the loading seat onto the worktable, adjust the position of the alignment block according to the relative position of the cutting line and the round bar.

A tension spring 28 is installed inside the mounting sleeve 25 and abuts against the connecting column 26. The tensioning wheel 27 is rotatably installed at the other end of the connecting column 26 and presses against the cutting line 13.

[0070] Before the loading seat 1 is installed on the worktable 5, the position of the alignment block 22 is adjusted according to the relative position of the cutting line 13 and the round bar 12. Then the loading seat 1 is installed on the worktable 5. During the installation process, the loading seat 1 moves back and forth so that both ends of the loading seat 1 are respectively aligned with the two alignment blocks 22 for positioning, ensuring the accuracy and convenience of the positioning of the loading seat 1.

[0071] The round bar 12 is mounted in the clamping groove 2 of the round bar 12 processing fixture by being fixed and bonded with paraffin wax. The clamping groove 2 is V-shaped, so the axis of the round bar 12 is located on the central surface of the clamping groove 2. During the cutting process, the cutting line 13 moves vertically downwards, thereby achieving the halving of the round bar 12. After the round bar 12 is halved, it is heated to remove the glue, and the edge of the halved round bar 12 is removed from the loading seat 1.

[0072] Example 4: A jig for machining round bars (see...) Figure 4 Its structure is similar to any one of embodiments 1 to 3, the main difference being that in this embodiment, positioning clamps 36 are installed on both the front and rear sides of the loading seat 1. The positioning clamps 36 have an L-shaped structure, and the two positioning clamps 36 are moved to move closer to or further away from each other. An arc-shaped positioning surface 37 is provided on the opposite surface of the two positioning clamps 36, and the positioning surface 37 is in contact with the outer wall of the round bar 12. A through groove 38 is formed between the opposite surfaces of the two positioning clamps 36. A drive screw 39 and a guide rod 23 are connected to the clamping seat. Both the drive screw 39 and the guide rod 23 pass through the loading seat 1. Both positioning clamps 36 are movably inserted and connected to the guide rod 23. The drive screw 39 is provided with two threaded sections 40 with opposite directions of rotation. The two positioning clamps 36 are respectively threaded to the two threaded sections 40. The rotation of the drive screw 39 drives the positioning clamps 36 to move. The fixed block 4 has extension plates 41 on both the front and rear sides. The extension plates 41 are equipped with supports 42. The drive screw 39 is rotatably mounted on the support 42. The drive screw 39 is equipped with a limiting plate 43. The limiting plate 43 is attached to the support 42 to achieve limiting.

[0073] After the round bar 12 is loaded into the clamping slot 2, the two positioning clamping strips 36 move closer to each other, so that the positioning surfaces 37 of the two positioning clamping strips 36 fit against the outer wall of the round bar 12, thereby positioning the round bar 12 and preventing it from shaking during the cutting process. A wire groove 38 is formed between the two positioning clamping strips 36, which positions the cutting line 13 and prevents deviation of the wire groove 38. The drive screw 39 rotates, and through the cooperation of two threaded sections 40 with opposite directions with the two positioning clamping strips 36, it drives the two positioning clamping strips 36 to move closer or further apart, making operation convenient and reliable. Other structures are the same as any one of embodiments 1 to 3.

[0074] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Other variations and modifications may be made without departing from the technical solutions described in the claims.
