[0034] The utility model is further described below in conjunction with the accompanying drawings. Example

[0035] like Figure 3 As shown, a glass syringe cutting auxiliary device of this embodiment includes a base plate 1, a moving part 2 is arranged on the base plate 1, and a fixing part 3 is arranged on the moving part 2;

[0036] like Figure 5 and Figure 7As shown, the fixing portion 3 has an expansion portion 33 for fixing the glass syringe. In this embodiment, the expansion portion 33 includes a base 331 arranged on the moving portion 2, a through hole is formed in the base 331, a conical slider 333 which can move up and down is arranged in the through hole, the outer portion of the conical slider 333 is an inverted cone, an expansion sleeve 332 is arranged on the outer portion of the conical slider 333, the interior of the expansion sleeve 332 is a conical surface matched with the conical slider 333, the conical slider 333 moves downward so that the outer diameter of the expansion sleeve 332 becomes larger to fix the glass syringe mounted on the expansion sleeve 332.

[0037] When the conical slider 333 moves upward, the outer diameter of the expansion sleeve 332 becomes smaller, so that the cut glass syringe can be easily taken out or the uncut glass syringe can be loaded. When the conical slider 333 moves downward, the outer diameter of the expansion sleeve 332 becomes larger, so that the glass syringe is supported and fixed to prevent the glass syringe from rotating during the cutting process. The moving part 2 can drive the fixing part 3, the expansion part 33 and the glass syringe to move forward and backward and left and right on the bottom plate 1, and the glass syringe is cut by the grinding wheel.

[0038] The expansion sleeve 332 is formed by dividing a cylinder along the axial direction. An annular spring 334 is sleeved on the outer wall of the expansion sleeve 332. The elastic force of the annular spring 334 constrains the expansion sleeve 332. When the conical slider 333 moves upward, the elastic force of the annular spring 334 causes the outer diameter of the expansion sleeve 332 to naturally decrease.

[0039] An annular buckle is arranged on the base 331, and an annular groove cooperating with the annular buckle is arranged on the inner wall of the expansion sleeve 332. The cooperating arrangement of the annular buckle and the annular groove can prevent the expansion sleeve 332 from moving up and down, thereby improving the cutting accuracy.

[0040] like Figure 3 and Figure 4 As shown, the movable part 2 includes a first slide rail 21 arranged on the base plate 1, a movable first slider is arranged on the first slide rail 21, a second slide rail 22 is fixedly arranged on the first slider, a movable second slider is arranged on the second slide rail 22, and a support plate 23 connected to the fixed part 3 is arranged on the second slider.

[0041] The first slide rail 21 is provided with first limit blocks at both ends to prevent the first slide block from falling off. Figure 1 As shown, when cutting the positioning groove 52 , the first limit block can further limit the groove depth of the groove to be cut, and second limit blocks are provided at both ends of the second slide rail 22 to prevent the second slide block from falling off.

[0042] In this embodiment, the first slide rail 21 is used to realize the longitudinal movement of the support plate 23, and the second slide rail 22 is used to realize the lateral movement of the support plate 23. A moving handle 25 is also installed on the support plate 23 to facilitate its movement.

[0043] like Figure 5As shown in FIG. 7 , the conical slider 333 has a guide shaft 335 that passes through the through hole of the base 331 , and a quick clamp 31 for controlling the up and down movement of the guide shaft 335 is provided on the support plate 23 , and the guide shaft 335 is connected to the quick clamp 31 through the connecting plate 323 .

[0044] The quick clamp 31 is a standard part purchased on the market, and has a swing handle, such as Figure 5 As shown, in the process of the swing handle swinging from the left side to the right side of the fixing part 3, the output rod of the quick clamp 31 moves downward, driving the connecting plate 323, the guide shaft 335 and the tapered slider 333 to move downward, thereby clamping the glass syringe; in the process of the swing handle swinging from the right side to the left side of the fixing part 3, the quick clamp 31 drives the connecting plate 323, the guide shaft 335 and the tapered slider 333 to move upward, thereby releasing the glass syringe.

[0045] like Figure 7 and Figure 8 As shown, a ratchet 321 is provided on the guide shaft 335, and a rotatable angle adjustment part 32 is provided on the output rod of the quick clamp 31. A ratchet 322 that matches the ratchet 321 is provided at one end of the angle adjustment part 32, and an adjustment rod 325 for rotating the ratchet 322 is provided at the other end of the angle adjustment part 32. According to the cutting requirements of the glass syringe, the ratchet 321 is equipped with a ratchet groove with the same angle. After the outer diameter of the expansion sleeve 332 is enlarged to fix the glass syringe, the glass syringe to be cut rotates the same angle each time the ratchet 321 is rotated. By controlling the rotation and locking of the ratchet 321, the position accuracy of the to-be-processed part on the tail plate of the glass syringe is guaranteed. The buckle of the ratchet 322 and the wheel groove of the ratchet 321 are both designed to be square, and the square design can achieve the purpose of two-way self-locking of the ratchet 321.

[0046] like Figure 6 As shown, the quick clamp 31 is also provided with a torsion spring 324 for returning the pawl 322. One end of the two output ends of the torsion spring 324 contacts the pawl 322, and the other end contacts the side of the connecting plate 323. When the adjusting rod 325 is pushed, the end of the pawl 322 that contacts the groove of the ratchet 321 overcomes the elastic force of the torsion spring 324. At this time, the pawl 322 is disengaged from the groove of the ratchet 321. At the same time, the ratchet 321 is rotated, and the force of pushing the adjusting rod 325 is removed. The elastic force of the torsion spring 324 makes the buckle end of the pawl 322 fit tightly with the outer surface of the ratchet 321. When the ratchet 321 rotates to the next wheel groove, the buckle of the pawl 322 automatically enters the wheel groove of the ratchet 321 to lock the ratchet 321, that is, the glass syringe enters the next position to be processed. Figure 3As shown, a baffle 34 for supporting the adjusting rod 325 is provided on the bottom plate 1. When the support plate 23 is driven to move to the extreme position along the first slide rail 21 by moving the handle 25, the baffle 34 supports the adjusting rod 325. At this time, when the support plate 23 is moved again, the adjusting rod 325 drives the pawl 322 to rotate due to the support of the baffle 34, and then the pawl 322 is disengaged from the wheel groove of the ratchet wheel 321, and the ratchet wheel 321 can rotate.

[0047] like Figure 3 , Figure 4 , Fig. 9 As shown, a limiting block 243 is provided on the first sliding block, and two limiting screws 242 are symmetrically provided on the limiting block 243;

[0048] The support plate 23 is provided with a slot limiting part 24, which has an extendable limiting pin 241, and a limiting space is formed between two limiting screws 242 to limit the movement of the extended limiting pin 241. The slot limiting part 24 is a standard part purchased on the market, and the limiting pin 241 can be freely extended or retracted therefrom. When cutting the auxiliary positioning groove 52 of the glass syringe, the limiting pin 241 is extended, and at this time, the two limiting screws 242 limit the limit pin 241 to limit the left and right movement distance of the support plate 23, and the cutting slot width is limited by adjusting the spacing between the two limiting screws 242; when cutting the anti-roll notch 51 of the glass syringe, the limiting pin 241 is retracted, and at this time, the support plate 23 can move left and right to a large extent.

[0049] like Figure 2 and Figure 3 As shown, a positioning ruler 4 is provided on the support plate 23, and the positioning ruler 4 has a notch for positioning the glass syringe. The width of the notch is consistent with the width of the scale line on the outer surface of the glass syringe to be processed, so the notch can be used to position the circumferential direction of the glass syringe to be processed.

[0050] like Figure 2 As shown, a protective cover is provided on the bottom plate 1, and most of the parts of the device can be concealed in the protective cover, thus playing a certain protective role therefor.

[0051] When the utility model positions and locks the glass syringe, the glass syringe to be processed is inserted into the outer surface of the expansion sleeve 332 with the opening facing downward, and the tail circular plate of the glass syringe directly contacts the upper surface of the base 331 to complete the upper and lower positioning, and then the glass syringe is rotated to align the scale line width position on its outer surface with the left and right groove walls of the notch above the positioning scale 4, and then the handle of the quick clamp 31 is rotated to turn it to the other side. At the same time, the output end of the quick clamp 31 drives the conical slider 333 to move downward through the connecting plate 323, so that each expansion sleeve 332 overcomes the elastic force of the annular spring 334 and expands, and finally the outer surface of the expansion sleeve 332 is completely fitted with the inner wall of the glass syringe, that is, the circumferential positioning of the glass syringe is completed.

[0052] When cutting the anti-roll notch 51, the limit pin 241 is retracted, and the external cutting machine is started at this time. The support plate 23 is moved forward to the limit position by moving the handle 25, thereby achieving the purpose of longitudinally cutting the edge of the tail of the glass syringe. Then, the support plate 23 is pulled back until the glass syringe is away from the grinding wheel, and the support plate 23 is moved left and right by about the thickness of the grinding wheel. Then, the longitudinal cutting is repeated in this way until the longitudinal flat edge is completely formed. Then, the support plate 23 is pushed forward to the limit position, and the support plate 23 is moved left and right to grind the flat edge of the notch, thereby completing the cutting of the anti-roll notch of the glass syringe.

[0053] After the anti-roll notch 51 is cut, the glass syringe needs to be controlled to turn, and the support plate 23 is pulled back to make the adjustment rod 325 contact with the baffle 34. When the support plate 23 is continued to be pulled back to the limit position, the baffle 34 overcomes the elastic force of the torsion spring 324 through the adjustment rod 325. At this time, the pawl 322 leaves the wheel groove of the ratchet 321. At the same time, the glass syringe is rotated to make the wheel groove of the ratchet 321 leave the pawl, and then the support plate 23 is moved forward to make the adjustment rod 324 leave the baffle 34. At this time, the buckle of the pawl plate 322 fits with the outer surface of the ratchet 321 under the elastic force of the torsion spring 324. When the ratchet 321 rotates to the next wheel groove and is close to the buckle of the pawl plate 322, the buckle of the pawl plate 322 enters the wheel groove under the elastic force of the torsion spring 324, completing the turning of the glass syringe and locking it again. The guide shaft 335 is non-fixedly connected to the connecting plate 323, that is, when the glass syringe, the expansion sleeve 332, the conical slider 333 and the ratchet 321 rotate, the connecting plate 323 does not rotate. Figure 7 As shown, a rotating shaft 329 is provided in the connecting plate 323, and the rotating shaft 329 is connected to the guide shaft 335 and sandwiches the connecting plate 323 in the middle. The guide shaft 335 can drive the rotating shaft 329 to rotate around the connecting plate 323, so that when the connecting plate 323 moves up and down, the guide shaft 335 and the rotating shaft 329 will be driven to move up and down, and when the guide shaft 335 rotates, the connecting plate 323 will not rotate. The connection between the other end of the connecting plate 323 and the output end of the quick clamp 31 can be a fixed connection.

[0054] After the glass syringe is turned, the auxiliary positioning groove 52 is cut, the limit pin 241 is extended, and the positions of the two limit screws 242 are adjusted according to the width of the groove to be cut, and then the support plate 23 is pushed forward to the limit position, that is, a longitudinal groove cutting is completed, and then the support plate 23 is pulled back until the glass tube is away from the grinding wheel, and then the support plate 23 is moved left and right by about the thickness of the grinding wheel, and then the longitudinal cutting is repeated in this way until the support plate 23 moves left and right to the telescopic rod of the limit pin 241 and contacts the limit screw 242, and the groove cutting work is completed.
