Abstract
Description
Technical Field
[0001] This utility model relates to the field of resin fiber cylinder polishing technology, and in particular to an automatic resin fiber cylinder polishing device. Background Technology
[0002] After the resin fiber tube is cut to the required length, its outer and inner circular walls need to be polished to meet the roughness requirements. Generally, the inner and outer circular walls of the resin fiber tube are relatively rough after molding, but they achieve a better smoothness after polishing. During the polishing process, the inner and outer walls of the resin fiber tube are polished separately using a grinding head on a grinding machine. However, the position of the resin fiber tube needs to be changed by the operator so that the grinding head can reach inside for inner wall polishing. Therefore, in the existing technology, the outer and inner circular walls need to be polished separately, which takes twice the polishing time and requires manual repositioning of the resin fiber tube to accommodate the grinding head position. Utility Model Content
[0003] (I) Technical Issues
[0004] The purpose of this invention is to provide an automatic grinding device for resin fiber tubes, which solves the problems in the prior art that require grinding the inner and outer circular walls of the resin fiber tubes separately, resulting in long grinding times and the need for manual position changes to adapt to the position of the grinding head.

A first rotary host is provided on one side of the sliding guide rail, and a three-jaw chuck for clamping the resin fiber tube is mounted on the first rotary host. A positioning seat for supporting the end of the resin fiber tube is mounted on the sliding guide rail. An outer cylindrical polishing mechanism located on one side of the first rotary host is mounted on the machine tool, and the outer cylindrical polishing mechanism is used to polish the outer cylindrical wall of the resin fiber tube. A second rotary host is slidably mounted on the sliding guide rail, and a pneumatic chuck is mounted on the second rotary host. A polishing rod is clamped on the pneumatic chuck, and an inner cylindrical grinding head is mounted on the end of the polishing rod. The inner cylindrical grinding head is used to polish the inner cylindrical wall of the resin fiber tube. A ball screw mechanism is provided inside the machine tool for driving the second rotary host to move relative to the sliding guide rail.
[0008] Preferably, the grinding mechanism includes a support frame mounted on the machine tool, the support frame having a transverse guide rail and a longitudinal guide rail slidably mounted on the transverse guide rail, a grinding base mounted on the longitudinal guide rail, a precision reducer mounted on the grinding base, a grinding head base mounted on the output shaft of the precision reducer, and a plurality of circumferentially distributed external grinding heads mounted on the grinding head base; the support frame has anti-rotation wedge blocks for limiting the rotation of the grinding head base.
[0009] Preferably, the number of the external cylindrical grinding heads is four, and the four external cylindrical grinding heads have different grinding roughness.
[0010] Preferably, the positioning seat includes a slide seat slidably mounted on the sliding guide rail, the slide seat having a placement notch, and three limiting frames evenly distributed around the placement notch on the slide seat, each limiting frame having a positioning roller rotatably mounted on it.

[0015] (III) Beneficial Effects
[0016] By installing a first rotary host on a machine tool, the resin fiber tube is clamped by a three-jaw chuck and driven to rotate. The outer circle grinding mechanism located on one side of the first rotary host grinds the outer circle wall of the resin fiber tube. At the same time, the second rotary host is driven to move by the ball screw mechanism integrated inside the machine tool. While driving the grinding rod and the inner circle grinding head to rotate, it moves into the resin fiber tube and simultaneously achieves the grinding of the inner circle wall.
[0017] Thus, the outer and inner circular walls are polished simultaneously during the rotation of the resin fiber tube, which can be completed in one polishing stroke, improving efficiency. Furthermore, the position of the resin fiber tube does not need to be adjusted during the polishing process; it only needs to be clamped and driven to rotate, reducing the degree of manual intervention and further improving polishing efficiency.

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0026] See Figures 1-5As shown in the figure, an automatic resin fiber tube polishing device is proposed in this embodiment of the present invention, including a machine tool 1 and a sliding guide rail 2 mounted on the machine tool 1. A first rotating host 3 is provided on one side of the sliding guide rail 2. The first rotating host 3 is fixed on the machine tool 1 and is generally composed of a motor, reducer, etc., mainly to realize the rotation action. A three-jaw chuck 4 for clamping the resin fiber tube is installed on the first rotating host 3. After the resin fiber tube is clamped by the three-jaw chuck 4, it rotates along with the first rotating host 3. Thus, during the polishing process, the resin fiber tube only needs to rotate and does not need to be switched in position. At the same time, a positioning seat 5 for supporting the end of the resin fiber tube is installed on the sliding guide rail 2. After the end of the resin fiber tube is supported by the positioning seat 5, the stability can be maintained during the rotation of the resin fiber tube and the tail of the end can be avoided, ensuring good coaxiality of rotation during subsequent polishing.
[0027] An outer circle grinding mechanism 6 is installed on the machine tool 1, located on one side of the first rotating host 3. The outer circle grinding mechanism 6 is used to grind the outer circle wall of the resin fiber tube. Specifically, the external cylindrical grinding mechanism 6 includes a support frame 61 mounted on the machine tool 1. The support frame 61 is provided with a transverse guide rail 62 and a longitudinal guide rail 63 slidably mounted on the transverse guide rail 62. A grinding base 64 is mounted on the longitudinal guide rail 63. A precision reducer 65 is mounted on the grinding base 64. A grinding head base 66 is mounted on the output shaft of the precision reducer 65. A plurality of external cylindrical grinding heads 67 are evenly distributed circumferentially on the grinding head base 66. At the same time, an anti-rotation wedge block 68 is provided on the support frame 61 to limit the rotation of the grinding head base 66. According to the grinding roughness requirements, the position of the external cylindrical grinding head 67 is changed by adjusting the position of the die head base through the precision reducer 65. The anti-rotation wedge block 68 limits the position of the die head base after adjustment, and the position of the external cylindrical grinding head 67 cannot be changed during the grinding process. The entire grinding base 64 can be positioned by the longitudinal guide rail 63 and the transverse guide rail 62. The longitudinal guide rail 63 is for manually adjusting the position of the grinding base 64 to match the center position of the outer cylindrical grinding head 67 after each installation of the resin fiber tube. The transverse guide rail 62 also includes a lead screw mechanism to enable the outer cylindrical grinding head 67 to move along the axis of the resin fiber tube during the grinding process, thereby completing the grinding of the entire outer cylindrical wall in one movement.
[0028] Meanwhile, a second rotary host 7 is slidably mounted on the sliding guide rail 2. A pneumatic chuck 8 is mounted on the second rotary host 7. The first rotary host 3 is generally composed of a motor, reducer, etc. The pneumatic chuck 8 achieves clamping by rotating an angle. Specifically, a grinding rod 9 is clamped on the pneumatic chuck 8. An inner grinding head 10 is mounted on the end of the grinding rod 9. The inner grinding head 10 is used to grind the inner wall of the resin fiber tube. At the same time, a ball screw mechanism is provided in the machine tool 1 to drive the second rotary host 7 to move relative to the sliding guide rail 2. Under the action of the ball screw mechanism, the entire second rotary host 7 is pulled to slide on the sliding guide rail 2, thereby moving the grinding rod 9 and the inner grinding head 10 into the resin fiber tube. The second rotary host 7 drives the grinding rod 9 and the inner grinding head 10 to rotate, completing the grinding of the entire inner wall in one movement.
[0029] Thus, the resin fiber tube is rotated by the first rotating host 3, and the outer cylindrical wall is polished by the outer cylindrical polishing mechanism 6 integrated on the machine tool 1. Meanwhile, the movable second rotating host 7 rotates the polishing rod 9 and the inner cylindrical polishing head 10, and the whole is pulled and moved to achieve the polishing of the outer cylindrical wall. Therefore, the inner and outer cylindrical walls are polished at the same time, which improves the polishing efficiency and eliminates the need to adjust the position of the resin fiber tube.
[0030] The precision reducer 65, longitudinal guide rail 63, transverse guide rail 62, lead screw mechanism, and ball screw mechanism mentioned above can all be installed and used using mature products, which are all mature technologies commonly used in the machine tool field.
[0031] Specifically, there are four external cylindrical grinding heads 67, each with a different grinding roughness. Adjacent external cylindrical grinding heads 67 are spaced 90° apart to ensure that the switching angle is more accurate when the precision reducer 65 rotates and switches between the external cylindrical grinding heads 67.
[0032] When the positioning seat 5 supports the resin fiber tube, it also ensures that the resin fiber tube can rotate flexibly. Specifically, the positioning seat 5 includes a slide seat 51 slidably mounted on the sliding guide rail 2. The slide seat 51 has a placement notch 52. Three limiting frames are evenly distributed around the placement notch 52 on the slide seat 51. Each limiting frame is rotatably mounted with a positioning roller 54. The slide seat 51 is adjusted according to the length of the resin fiber tube to allow the end of the resin fiber tube to extend into the placement notch 52 and be positioned at three points by the three positioning rollers 54. The positioning rollers 54 themselves can rotate, which allows the resin fiber tube to rotate flexibly while supported. At the same time, the placement notch 52 also facilitates the grinding of the supported part by the external cylindrical grinding head 67.
[0033] Specifically, the internal grinding head 10 also needs to be replaced according to the roughness requirements. In order to facilitate the replacement and placement of the internal grinding head 10, a stand 11 is installed on the support frame 61. Four consumable cylinders 12 are installed at intervals on the stand 11, and each consumable cylinder 12 contains an internal grinding head 10 with different grinding roughness.
[0034] Meanwhile, an opening notch 120 is provided on the consumable material cylinder 12, and a cylinder 13 corresponding to the top of each consumable material cylinder 12 is installed on the upright frame 11. Under the action of the opening notch 120, the consumable material cylinder 12 has a certain deformation effect, which makes it easier to insert and place the inner cylindrical grinding head 10. The cylinder 13 can apply force to push the inner cylindrical grinding head 10 out of the consumable material cylinder 12. Generally speaking, the inner cylindrical grinding head 10 is inserted from the bottom of the consumable material cylinder 12, and the elastic force of the consumable material cylinder 12 holds the inner cylindrical grinding head 10 tightly so that it will not fall off when placed.
[0035] Meanwhile, a receiving hopper 14 located below the three-jaw chuck 4 is installed on the machine tool 1. A negative pressure dust suction pump connected to the outlet of the receiving hopper 14 is installed inside the machine tool 1. A dust collection bag is installed at the outlet of the negative pressure dust suction pump. During the grinding process, dust will fall. After the dust is collected and recycled by the receiving hopper 14, the dust is accelerated to the bottom by the action of the internal negative pressure dust suction pump and collected by the dust collection bag, reducing the accumulation of dust at the grinding position.
[0036] Meanwhile, a PLC control module and a touch control screen are integrated inside the casing of the first rotating host 3. The PLC control module and the touch control screen that implement the corresponding control are existing technologies. This embodiment does not involve the specific circuit control part of each device.
