Description

Technical Field

[0001] The present invention relates to a glove mold ring sleeve surface polishing device and method based on a clamping and positioning structure. Background Art

[0002] The glove mold ring sleeve belongs to one of the components in the glove mold. The glove mold can be divided into a plastic mold and an alloy mold according to the material. The common one is the aluminum alloy glove mold. The aluminum alloy glove mold has stronger hardness, more subtle thermal expansion, and longer service life, so it is more widely used.

[0003] Under the process requirements of lightweight design and material saving, the aluminum alloy glove mold generally adopts a hollow structure; in the actual glove forming production process of the internally hollow aluminum alloy mold, in order to prevent the molten flowable plastic material from entering the inside of the aluminum alloy glove mold, it generally needs to be sealed; industrially, it is generally sealed by installing a sealing plug at the port of the mold, and the seal is fixed by the ring sleeve.

[0004] In order to ensure that the ring sleeve matches the port size of the aluminum alloy glove mold, during the production process of the ring sleeve, the size needs to be accurately grasped. And in order to ensure that the ring sleeve can be completely fitted with the rubber part without gaps, the surface of the ring sleeve also needs to be smooth.

Specific implementation manner

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] In addition, an element in the present invention is referred to as being "fixed to" or "disposed on" another element, and it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0030] Please refer to Figures 1 - 9 , in the embodiment of the present invention, a glove mold ring sleeve surface polishing device based on a clamping and positioning structure includes a base 1 and a first vertical plate 2 and a second vertical plate 15 installed on the base 1, and further includes: A clamping and positioning structure, with one set provided on each of the base 1 and the first vertical plate 2, for clamping and fixing the parts to be processed, and the two sets of clamping and positioning structures are connected to a spacing adjustment mechanism installed between the base 1 and the first vertical plate 2; A power mechanism, installed between the base 1 and the second vertical plate 15 and connected to the two sets of clamping and positioning structures, and the power mechanism can drive the two sets of clamping and positioning structures to drive the parts to be processed to rotate; There are two arc-shaped abrasive sheets 32 movably arranged on the base 1, and the two arc-shaped abrasive sheets 32 are connected to a bidirectional driving mechanism installed on the base 1. The bidirectional driving mechanism is connected to a unidirectional triggering mechanism arranged on the side of the second vertical plate 15, and the unidirectional triggering mechanism cooperates with the power mechanism; When the unidirectional triggering mechanism cooperates with and triggers the power mechanism, it can drive the bidirectional driving mechanism to drive the two arc-shaped abrasive sheets 32 to move away from each other, so as to change the position of the arc-shaped abrasive sheets 32 for polishing the surface of the part.

[0031] In actual processing, the parts to be processed are clamped and fixed by two groups of the clamping and positioning structures. Subsequently, the power mechanism works to drive the two groups of the clamping and positioning structures to drive the parts to be processed to rotate. Thus, the two arc-shaped abrasive sheets 32 can smoothly polish the surface of the parts. When the power mechanism cooperates with the unidirectional triggering mechanism, the unidirectional triggering mechanism will drive the bidirectional driving mechanism to move, and the bidirectional driving mechanism will drive the two arc-shaped abrasive sheets 32 to move away from each other. In this way, the cycle is repeated, and the processing position of the arc-shaped abrasive sheets 32 on the part surface is changed; In summary, through the mutual cooperation between various mechanisms and components, two groups of the clamping and positioning structures are used to fix the parts to be processed, and the change of the processing position is realized through the cooperation between the power mechanism and the unidirectional triggering mechanism. Therefore, the effective automatic processing function of the part surface is realized, which greatly reduces the burden of the staff and is suitable for popularization and use.

[0032] Please refer to again Figure 2 、 Figure 3 、 Figure 5 and Figure 6 , a rotating shaft 11 is rotatably installed on each of the base 1 and the first vertical plate 2. The two rotating shafts 11 are connected to the power mechanism. The clamping and positioning structure includes a sleeve 6 slidably sleeved on the rotating shaft 11 and connected to the spacing adjustment mechanism, and an assembly plate 7 fixed to the sleeve 6. The assembly plate 7 is arranged in a "cross" shape, and a plurality of sets of threaded fasteners are equidistantly arranged on the circumference thereof.

[0033] The threaded fastener includes a second bidirectional lead screw 8 rotatably installed on the assembly plate 7 and two sliders 9 symmetrically arranged on the second bidirectional lead screw 8. The two sliders 9 are threadedly connected to the second bidirectional lead screw 8, slidably connected to the assembly plate 7, and a clamping plate 10 is further arranged on the slider 9.

[0034] The spacing adjustment mechanism includes a first bidirectional lead screw 3 rotatably installed between the base 1 and the first vertical plate 2, and two threaded sleeves 4 symmetrically arranged on the first bidirectional lead screw 3. Both of the two threaded sleeves 4 are threadedly connected to the first bidirectional lead screw 3. A cross plate 5 is further provided on the threaded sleeve 4, and the cross plate 5 is rotatably connected to the sleeve 6.

[0035] During use, the staff places the part to be processed between the two assembly plates 7. Subsequently, the first bidirectional lead screw 3 is rotated, and the two threaded sleeves 4 simultaneously perform threaded engagement with the first bidirectional lead screw 3 and move closer to each other until the clamping plate 10 moves to a position suitable for clamping the part. Subsequently, the second bidirectional lead screw 8 is rotated, and the two sliders 9 simultaneously perform threaded engagement with the second bidirectional lead screw 8 and move closer to each other. Thus, the two clamping plates 10 can complete the fixation of the part, ensuring the smooth progress of subsequent processing.

[0036] Please refer to again Figure 1 , the power mechanism includes a one-way lead screw 12 rotatably installed between the base 1 and the second vertical plate 15, a lifting tube 16 sleeved on the one-way lead screw 12 and threadedly connected to the one-way lead screw 12, and a driving motor 13 installed on the second vertical plate 15. One end of the one-way lead screw 12 away from the base 1 is connected to the output end of the driving motor 13; Wherein, a guide wheel 1601 is further provided on the lifting tube 16, and the guide wheel 1601 is in rolling fit with the second vertical plate 15. The one-way lead screw 12 is also connected to the two rotating shafts 11 through two first transmission belts 14 respectively. Two strip-shaped protrusions are provided on the outer wall of the rotating shaft 11, and two strip-shaped grooves adapted to the strip-shaped protrusions are opened on the inner wall of the sleeve 6.

[0037] During operation, the driving motor 13 drives the one-way lead screw 12 to rotate forward. At this time, the one-way lead screw 12 drives the rotating shaft 11 to rotate through the first transmission belt 14. Thus, the rotating shaft 11 drives the sleeve 6 to rotate through the strip-shaped protrusions on its outer wall and the strip-shaped grooves on the inner wall of the sleeve 6. Thus, the assembly plate 7 drives the part to rotate, enabling the arc-shaped abrasive sheet 32 to polish the surface of the part; Meanwhile, under the guiding action of the guide wheel 1601, the lifting tube 16 performs threaded engagement with the one-way lead screw 12 and gradually moves downward, causing the one-way trigger mechanism to be triggered multiple times. Each time the one-way trigger mechanism is triggered, it can drive the bidirectional drive mechanism to drive the two arc-shaped abrasive sheets 32 to move away from each other by a certain distance, realizing the change of the polishing position.

[0038] Please refer to again Figure 4The bidirectional driving mechanism includes a third bidirectional screw rod 29 rotatably mounted on the base 1 and two lifting plates 28 symmetrically arranged on the third bidirectional screw rod 29, and the third bidirectional screw rod 29 is connected to the unidirectional trigger mechanism; Among them, a cylinder 31 is installed on each of the two lifting plates 28, and the two arc-shaped sand pieces 32 are respectively fixed to the movable ends of the two cylinders 31. A column 30 is also provided on the base 1, and the column 30 passes through the two lifting plates 28. The two lifting plates 28 are slidably connected to the column 30.

[0039] Whenever the one-way trigger mechanism moves, it will drive the third two-way screw rod 29 to rotate, so that the column 30 guides the two lifting plates 28, so that the two lifting plates 28 are simultaneously threadedly engaged with the third two-way screw rod 29 and move away from each other, automatically changing the position of the arc-shaped sand piece 32 for surface treatment of the part.

[0040] Please refer again Figure 1 , Figure 4 , Figure 7 , Figure 8 as well as Figure 9 The one-way trigger mechanism includes a transmission plate 21 movably arranged on the side of the second vertical plate 15 away from the lifting tube 16, and a plurality of sets of elastic telescopic components are arranged between the transmission plate 21 and the second vertical plate 15, and a transmission structure is arranged between the transmission plate 21 and the third bidirectional screw rod 29.

[0041] The elastic telescopic assembly includes a guide cylinder 17 fixed on the second vertical plate 15, a telescopic rod 18 slidably disposed in the guide cylinder 17 and fixed to the transmission plate 21, and a cylindrical spring 20 disposed in the guide cylinder 17; A boss 19 is provided at one end of the telescopic rod 18 away from the transmission plate 21, and the cylindrical spring 20 is sleeved on the outer periphery of the telescopic rod 18, and the two ends are respectively connected to the boss 19 and the inner wall of the guide cylinder 17; A plurality of driven blocks 22 are evenly installed on one side of the transmission plate 21 . The driven blocks 22 are provided with inclined surfaces and cooperate with the driving wheels 1602 installed on the lifting tube 16 .

[0042] The transmission structure includes a fixed frame 23 fixed on the transmission plate 21 and a ratchet 24 rotatably mounted on the base 1. The rotating shaft of the ratchet 24 is connected to a transmission shaft 26 rotatably mounted on the base 1 through a bevel gear set 25. The transmission shaft 26 is connected to the third bidirectional screw rod 29 through a second transmission belt 27. A plurality of inclined grooves are equidistantly provided at the bottom of the fixed frame 23, and a pawl cooperating with the ratchet 24 is hinged in each of the inclined grooves.

[0043] Specifically, the bevel gear set 25 includes a first bevel gear coaxially installed with the ratchet wheel 24 and a second bevel gear installed on the transmission shaft 26, and the second bevel gear meshes with the first bevel gear.

[0044] During the downward movement of the lifting pipe 16, when the driving wheel 1602 passes through the inclined surface on the driven block 22, the driven block 22 will be displaced. Thus, the driven block 22 drives the transmission plate 21 to move away from the second vertical plate 15. Correspondingly, the telescopic rod 18 slides outward relative to the guide cylinder 17, and the cylindrical spring 20 is compressed. During this process, the pawl at the bottom of the fixed frame 23 cannot rotate when passing through the ratchet wheel 24, resulting in the rotation of the ratchet wheel 24. The rotating shaft of the ratchet wheel 24 drives the transmission shaft 26 to rotate through the bevel gear set 25. The transmission shaft 26 drives the third bidirectional lead screw 29 to rotate through the second transmission belt 27, so that the two arc-shaped abrasive sheets 32 move away from each other to change the polishing position. When the driving wheel 1602 is separated from the driven block 22, the cylindrical spring 20 rebounds and all components return to their original positions. During this process, the pawl at the bottom of the fixed frame 23 will rotate when passing through the ratchet wheel 24, and the ratchet wheel 24 does not rotate.

[0045] As another embodiment of the present invention, a part processing method is also proposed. Using the glove mold ring sleeve surface polishing device based on the clamping and positioning structure described above, it includes the following steps: Step 1, clamping and fixing the part to be processed through the two groups of clamping and positioning structures and the spacing adjustment mechanism; Step 2, adjusting the positions of the arc-shaped abrasive sheets 32 to ensure that the two arc-shaped abrasive sheets 32 are in contact with the surface of the part; Step 3, starting the power mechanism, driving the two groups of clamping and positioning structures by the power mechanism to drive the part to rotate, and the power mechanism cooperates with the unidirectional trigger mechanism; Step 4, the unidirectional trigger mechanism moves, driving the bidirectional driving mechanism to move, so that the bidirectional driving mechanism drives the two arc-shaped abrasive sheets 32 to move away from each other to change the processing position.
