Description

Technical Field

[0001] This invention relates to a processing apparatus for small-diameter glass rods. Background Technology

[0002] Existing glass rod products are generally processed using cylindrical surface 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 on processing high-precision surface products is very limited.

[0004] If cylindrical tumbling polishing equipment is used for processing, when processing small-diameter round bars (e.g., products with a diameter less than 5mm), torsional fracture and ejector pin pressure fracture are prone to occur; the main reasons are as follows:

[0005] Because the product is too small, during the processing of the tumbler, the drive wheel drives the driven wheel. Because the driven wheel is too heavy, the torque required to drive it is too large. The round bar product clamped between the drive wheel and the driven wheel is prone to breakage.

[0006] The minimum pressure of the existing tumbler polishing machine's ejector pin is the weight of the support itself, about 2-3 kg; for small round bar products, this is still too heavy and can easily cause the product to break.

[0007] Based on the above, existing technologies need to be improved. Summary of the Invention

[0008] This invention provides a processing device for small-diameter glass rods. The invention aims to solve the technical problem that small-diameter glass rods are prone to breakage when processed using existing tumble polishing equipment.

[0009] This invention is achieved through the following technical solution:

[0010] A processing device for small-diameter glass rods includes a frame, a polishing tool holding device, an active pressing device, a driven pressing device, and bearings;

[0011] The active pressing device includes an active motor, an active motor adapter for driving and connecting to the active motor, and a tooling pressing chuck coaxially and fixedly connected to the active motor adapter for connecting to the workpiece.

[0012] The driven pressing device includes a driven motor, a driven motor adapter for driving the driven motor, a workpiece, and a tooling pressing chuck.

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

[0014] The first tooling clamp and the second tooling clamp are coaxial and spaced apart.

[0015] The small-diameter glass 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 rod to be processed to rotate, and then drives the relatively light bearing to rotate. The torque generated on the small-diameter glass rod to be processed is small, so it is not easy to break.

[0016] Furthermore, the polishing tool holding device includes a vertically positioned ejector pin and a clamping seat for holding the ejector pin and moving it along the length of the outer peripheral wall of the small-diameter glass rod to be processed.

[0017] The ejector pin includes a pressing section, a clamping section, an elastic element, and a limiting element. The clamping section has an inner hole extending along its length in its lower end body near the pressing section. The top end of the pressing section is rotatably sleeved in the inner hole. The elastic element is disposed in the inner hole and located between the top end of the pressing section and the bottom wall of the inner hole of the clamping section.

[0018] The top of the pressing section fitted inside the inner hole is provided with an annular flange. The limiting member includes an outer sleeve threaded onto the outside of the clamping section and a limiting ring fixed to the bottom of the outer sleeve. The outer diameter of the annular flange is larger than the inner diameter of the limiting ring.

[0019] In this design, the ejector pin presses against the polishing abrasive to polish the outer peripheral wall of the small-diameter glass rod to be processed. Due to the elastic element, the radial force of the ejector pin on the small-diameter glass rod to be processed is reduced during polishing, thereby preventing the ejector pin from breaking due to excessive pressure during product processing.

[0020] Specifically, the top of the pressing section fitted inside the inner hole is provided with an annular flange, and the limiting member includes an outer sleeve threaded onto the outside of the clamping section and a limiting ring fixed to the bottom of the outer sleeve. The outer diameter of the annular flange is larger than the diameter of the limiting ring.

[0021] Specifically, the elastic element can be a spring.

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

[0023] Compared with the prior art, the present invention has the following advantages: In use, the small-diameter glass rod to be processed is sandwiched between the active pressing device and the driven pressing device of the present invention. The active pressing device drives the small-diameter glass rod to be processed to rotate, and then drives the bearing with a relatively small weight to rotate. The torque generated on the small-diameter glass rod to be processed is small, so it is not easy to break.

[0024] In this design, the ejector pin presses against the polishing abrasive to polish the outer peripheral wall of the small-diameter glass rod to be processed. Due to the elastic element, the radial force of the ejector pin on the small-diameter glass rod to be processed is reduced during polishing, thereby preventing the ejector pin from breaking due to excessive pressure during product processing.

[0031] like Figure 3 As shown, the active pressing device 2-1 includes an active motor 2-1-3, an active motor adapter connecting workpiece 2-1-1 for driving connection with the active motor 2-1-3, and a tooling pressing chuck 2-1-2 coaxially and fixedly connected to the active motor adapter connecting workpiece 2-1-1.

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

[0033] The outer ring of the bearing 2-3 is coaxially and fixedly connected to the driven motor adapter workpiece 2-1-1, and the inner ring of the bearing 2-3 is coaxially and fixedly connected to the tooling top pressure chuck 2-2-2.

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

[0035] like Figure 2As shown, the polishing tool holding device 3 includes a vertically placed 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 rod to be processed.

[0036] The ejector pin 3-1 includes a pressing section 3-1-1, a clamping section 3-1-2, an elastic element 3-1-3, and a limiting element 3-1-4. The clamping section 3-1-2 has an inner hole 3-1-5 extending along its length in its lower end near the pressing section 3-1-1. The top end of the pressing section 3-1-1 is rotatably sleeved in the inner hole 3-1-5. The elastic element 3-1-3 is disposed in the inner hole 3-1-5 and is located between the top end of the pressing section 3-1-1 and the bottom wall of the inner hole 3-1-5 of the clamping section 3-1-2.

The outer diameter of the annular flange is larger than the inner diameter of the limiting ring.

[0038] In this design, the ejector pin 3-1 presses against the polishing abrasive to polish the outer peripheral wall of the small-diameter glass rod to be processed. Due to the elastic element, the radial force of the ejector pin 3-1 on the small-diameter glass rod to be processed is reduced during polishing, thereby preventing the ejector pin from breaking due to excessive pressure during product processing.

The outer diameter of the annular flange is larger than the diameter of the limiting ring.

[0040] The elastic element 3-1-3 described in this embodiment can be a spring.

[0041] In order to extend the service life, the two ends of the ejector pin 3-1 in the length direction are rounded in this embodiment.
