Description

Technical Field

[0001] The invention relates to a processing device for a small-caliber glass round rod. Background Art

[0002] Existing glass round rod products are generally processed by cylindrical rolling polishing equipment or double-sided polishing equipment;

[0003] If double-sided polishing equipment is used for processing, the surface shape often cannot achieve high precision; the effect of processing high-precision products on the surface shape is very limited;

[0004] If cylindrical rolling equipment is used for processing, when processing small-diameter round bars (for example, products with a diameter less than 5mm), torsion fracture and ejector pressure fracture are likely to occur; the main reasons are as follows:

[0005] Because the product is too small, during the rolling and polishing machine processing, the driving wheel drives the driven wheel. Because the driven wheel is too heavy, the torque required to drive is too large, and the round bar product clamped between the driving wheel and the driven wheel is prone to breakage;

[0006] The minimum pressure of the existing roller polishing machine's ejector pin is the weight of the bracket, about 2-3kg; for small round rod products, it is still too heavy and it is very easy to crush the product.

[0007] Based on the above, the prior art needs to be improved. Summary of the invention

[0008] The invention provides a processing device for a small-diameter glass round rod, and aims to solve the technical problem that the small-diameter glass round rod is easy to break when being processed by the existing rolling and throwing equipment.

[0009] The present invention is achieved through the following technical solutions:

[0010] A processing device for a small-caliber glass round rod comprises a frame, a polishing tool holding device, an active pressing device, a driven pressing device and a bearing;

[0011] The active pressing device comprises an active motor, an active motor adapter connecting a workpiece for drivingly connecting with the active motor, and a tooling pressing chuck 1 coaxially fixedly connected with the active motor adapter connecting workpiece;

[0012] The driven pressing device comprises a driven motor, a driven motor adapter connected to the driven motor, a workpiece and a second tooling pressing chuck;

[0013] The outer ring of the bearing is coaxially fixedly connected to the driven motor transfer connection workpiece, and the inner ring of the bearing is coaxially fixedly connected to the second tooling top pressure chuck;

[0014] The first tool pressing chuck and the second tool pressing chuck are coaxial and spaced apart.

[0015] A small-diameter glass round rod to be processed is sandwiched between the active pressing device and the driven pressing device. The active pressing device drives the small-diameter glass round rod to be processed to rotate, and then drives the lighter bearing to rotate. The torque generated on the small-diameter glass round rod to be processed is small, so it is not easy to break.

[0016] Furthermore, the polishing tool holding device includes a vertical ejector pin and a clamping seat for clamping the ejector pin and driving the ejector pin to move along the length direction of the outer peripheral wall of the small-diameter glass round rod to be processed.

[0017] The ejector pin comprises an ejection section, a clamping section, an elastic member and a stopper. The clamping section is provided with an inner hole extending in the length direction in its lower end body close to the ejection section. The top end of the ejection section is rotatably sleeved in the inner hole. The elastic member is arranged in the inner hole and is located between the top end of the ejection section and the bottom wall of the inner hole of the clamping section.

[0018] An annular flange is provided on the top of the pressing section sleeved in the inner hole, and the limiting member includes an outer sleeve threadedly sleeved outside the clamping section and a limiting ring fixed to the bottom of the outer sleeve, and the outer diameter of the annular flange is greater than the inner diameter of the limiting ring.

[0019] The ejector pin of the present invention presses the polishing abrasive tool to polish the outer peripheral wall of the small-diameter glass round rod to be processed. Due to the elastic member, the radial force of the small-diameter glass round rod to be processed becomes smaller during polishing, thereby preventing the ejector pin from breaking due to excessive pressure during product processing.

[0020] Specifically, an annular flange is provided on the top of the top pressure section sleeved in the inner hole, and the limiting member includes an outer sleeve threadedly sleeved outside the clamping section and a limiting ring fixed to the bottom of the outer sleeve, and the outer diameter of the annular flange is greater than the diameter of the limiting ring.

[0021] Specifically, the elastic member may be a spring.

[0022] Specifically, in order to extend the service life, both ends of the ejector pin in the length direction are respectively provided with chamfers.

[0023] Compared with the prior art, the present invention has the following beneficial effects: when in use, a small-diameter glass round rod to be processed is clamped between the active pressing device and the driven pressing device of the present invention, the active pressing device drives the small-diameter glass round rod to be processed to rotate, and then drives the smaller weight bearing to rotate, the torque generated on the small-diameter glass round rod to be processed is small, so it is not easy to break.

[0024] The ejector pin of the present invention presses the polishing abrasive tool to polish the outer peripheral wall of the small-diameter glass round rod to be processed. Due to the elastic member, the radial force of the small-diameter glass round rod to be processed becomes smaller during polishing, thereby preventing the ejector pin from breaking due to excessive pressure during product processing.

[0032] The driven pressing device 2-2 includes a driven motor 2-2-3, a driven motor adapter connected to the driven motor 2-2-3, a workpiece 2-2-1 and a tooling pressing chuck 2-2-2;

[0033] The outer ring of the bearing 2-3 is coaxially fixedly connected to the driven motor transfer connection workpiece 2-1-1, and the inner ring of the bearing 2-3 is coaxially fixedly connected to the second tooling top pressing chuck 2-2-2;

[0034] The tooling top pressing chuck 1 2-1-2 and the tooling top pressing chuck 2 2-2-2 are coaxial and spaced apart.

[0035] like Figure 2As shown, the polishing tool holding device 3 includes a vertical ejector pin 3-1 and a clamping seat 3-2 for clamping the ejector pin 3-1 and driving the ejector pin 3-1 to move along the length direction of the outer peripheral wall of the small-diameter glass round rod to be processed.

[0036] The ejector pin 3-1 comprises an ejection section 3-1-1, a clamping section 3-1-2, an elastic member 3-1-3 and a stopper 3-1-4. The clamping section 3-1-2 is provided with an inner hole 3-1-5 extending in the length direction in its lower end body near the ejection section 3-1-1. The top end of the ejection section 3-1-1 is rotatably sleeved in the inner hole 3-1-5. The elastic member 3-1-3 is arranged in the inner hole 3-1-5 and is located between the top end of the ejection section 3-1-1 and the bottom wall of the inner hole 3-1-5 of the clamping section 3-1-2.

[0038] The ejector pin 3-1 of the present invention presses against the polishing tool to polish the outer peripheral wall of the small-diameter glass round rod to be processed.
