[0003] Since the blow molding process needs to be kept closed and leak-free, the end surface finish of the neck hoop is required to be high, and no sand holes, pits, or burrs are allowed. Generally, the neck hoop can be formed by casting, and after forming, the circumferential surface and end surface of the neck hoop are finely processed by lathes, milling machines, and boring machines.

[0004] Although the roughness is improved after fine machining, it still cannot meet the surface requirements of blow molding. Therefore, it needs to be further processed to further improve its finish, roughness and smoothness. Generally, grinding and polishing are often used to ensure its finish.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0027] See also Figure 1-Figure 7 In an embodiment of the present invention, a double-end-face switching and locking hand-form neck hoop end surface finish processing device comprises a base 1 and a vertical plate 2 vertically mounted on the base 1, and also comprises: A horizontal plate 5 is movably arranged on the vertical plate 2 and connected to a pneumatic lifting mechanism installed on the vertical plate 2. A grinding wheel 10 is movably arranged below the horizontal plate 5 through a radial movable mechanism. The radial movable mechanism can drive the grinding wheel 10 to make a circular motion and move in a horizontal direction, so that the position of the grinding wheel 10 for polishing the end surface of the neck hoop can be changed; Two second assembly plates 15 are rotatably mounted on the base 1, and the two second assembly plates 15 are arranged opposite to each other, and each of them is provided with a group of stable clamping mechanisms for fixing the neck hoop to be processed. The rotating shaft of the second assembly plate 15 is connected to the locking mechanism arranged on the base 1, and is also connected to a one-way transmission mechanism, and the one-way transmission mechanism cooperates with the pneumatic lifting mechanism.

[0028] In actual use, the neck hoop to be processed is placed in the two groups of the stable clamping mechanisms, and the neck hoop is fixed by the two groups of the stable clamping mechanisms to ensure that the neck hoop can remain stable during the subsequent processing, thereby ensuring the smooth processing; Subsequently, the pneumatic lifting mechanism drives the horizontal plate 5 to descend until the grinding wheel 10 contacts the end face of the neck hoop. Subsequently, the radial movable mechanism works to drive the grinding wheel 10 to perform circular motion on the end face of the neck hoop to achieve annular polishing. During the circular motion, the grinding wheel 10 can move along the radial direction of its circular motion to automatically change the polishing position. This reciprocating process achieves comprehensive processing of the end face of the neck hoop. When one end surface of the neck hoop is processed, the pneumatic lifting mechanism drives the horizontal plate 5 and the grinding wheel 10 to rise, and in the latter part of the rising stroke of the grinding wheel 10, the one-way transmission mechanism is triggered to drive the second assembly plate 15 to rotate 180°, so that the neck hoop is turned over, and finally the turned neck hoop is processed; In summary, through the mutual cooperation between various mechanisms and components, the effective processing function of the neck hoop end face is realized, and through the cooperation of the pneumatic lifting mechanism and the one-way transmission mechanism, the automatic switching of the neck hoop end face is realized, which greatly improves the degree of automation of processing, can effectively improve processing efficiency, reduce labor burden, and is suitable for popularization and use.

[0029] Please refer again Figure 6 The radial movable mechanism includes a circumferential drive assembly installed on the transverse plate 5 and a threaded drive structure connected to the circumferential drive assembly. The circumferential drive assembly is used to drive the grinding wheel 10 to perform circular motion, and the threaded drive mechanism is intermittently triggered during the circular motion of the grinding wheel 10.

[0030] The circular drive assembly includes a first assembly plate 6 rotatably mounted on the bottom of the horizontal plate 5 and a first drive motor 7 arranged on the upper part of the horizontal plate 5, and the rotating shaft of the first assembly plate 6 is connected to the output end of the first drive motor 7, and the threaded drive structure can drive the grinding wheel 10 to move along the length direction of the first assembly plate 6.

[0031] The thread drive structure includes a one-way screw 8 rotatably mounted on the bottom of the first assembly plate 6 and a transverse plate 9 provided on the one-way screw 8 and threadedly connected to the one-way screw 8. A second drive motor 11 is installed at the bottom of the transverse plate 9. The grinding wheel 10 is fixed to the output shaft of the second drive motor 11. A guide rod is also provided at the bottom of the first assembly plate 6. The guide rod passes through the transverse plate 9 and is slidably connected thereto. A driven collar 12 is rotatably mounted on one side of the first assembly plate 6 , the rotating shaft of the driven collar 12 is connected to the one-way screw 8 via a first transmission belt 13 , and an arc-shaped toothed plate 14 cooperating with the driven collar 12 is fixedly provided at the bottom of the cross plate 5 .

[0032] When the pneumatic lifting mechanism drives the transverse plate 5 to descend and makes the grinding wheel 10 contact with the end face of the neck hoop, the first drive motor 7 and the second drive motor 11, so that the first drive motor 7 drives the first assembly plate 6 to rotate, the second drive motor 11 drives the grinding wheel 10 to rotate, and the grinding wheel 10 makes a circular motion on the end face of the neck hoop, when the driven neck hoop 12 is engaged with the arc-shaped tooth plate 14, the driven neck hoop 12 will rotate, and its rotating shaft drives the one-way screw 8 to rotate through the first transmission belt 13, under the guiding action of the guide rod (not shown in the figure), the transverse plate 9 and the one-way screw 8 are threadedly matched and move along the length direction of the first assembly plate 6, so as to achieve the effect of automatically changing the polishing position.

[0033] It should be noted that the first drive motor 7 is a servo motor with bidirectional drive at the output end, and this application does not make any specific restrictions on its specific model.

[0034] Please refer again Figure 2 The pneumatic lifting mechanism includes a cylinder 3 installed on the base 1 and a sleeve plate 4 slidably arranged on the vertical plate 2. One side of the sleeve plate 4 is fixed to the movable end of the cylinder 3, and the other side is fixed to the horizontal plate 5.

[0035] Furthermore, in actual use, the cylinder 3 can also be replaced by an electric telescopic rod or a hydraulic cylinder. This application does not make any specific restrictions on this and can be selected according to actual needs.

[0036] Please refer again Figure 5 The stable clamping mechanism includes a bidirectional screw rod 16 rotatably mounted on the second assembly plate 15, a fixed rod 17 fixed to the second assembly plate 15, and two movable plates 18 symmetrically arranged on the bidirectional screw rod 16 and threadedly connected to the bidirectional screw rod 16; The fixing rod 17 passes through the two movable plates 18 , and the two movable plates 18 are slidably connected to the fixing rod 17 . A clamping member 19 arranged in an arc shape is respectively arranged on one side of the two movable plates 18 away from the second assembly plate 15 .

[0037] When in use, the neck hoop to be processed is placed between the two clamping members 19, and then the bidirectional screw rod 16 is rotated, and the fixed rod 17 guides the two movable plates 18, so that the two movable plates 18 will simultaneously engage with the bidirectional screw rod 16 through threads and move toward each other, and finally, the two clamping members 19 will complete the fixed clamping of the neck hoop (the two clamping members 19 clamp the teeth on the neck hoop to avoid covering the end surface of the neck hoop).

[0038] Please refer again Figure 5 and Figure 6 The one-way transmission mechanism includes a ratchet 21 rotatably mounted on the base 1 and a movable arm 20 fixed to the side of the sleeve plate 4, and the rotation axes of the ratchet 21 and the second assembly plate 15 are connected by a second transmission belt 22. The movable arm 20 is provided with a plurality of inclined grooves equidistantly on one side facing the ratchet 21, and a ratchet pawl cooperating with the ratchet 21 is rotatably mounted in each of the inclined grooves.

[0039] When the cylinder 3 drives the sleeve plate 4 to slide downward on the vertical plate 2, the pawl on the movable arm 20 will be deflected when passing the ratchet 21, and the ratchet 21 will not rotate. After one end face of the neck hoop is processed, when the cylinder 3 drives the sleeve plate 4 to rise, the inclined groove limits the pawl when passing the ratchet 21, so that the pawl cannot rotate. Then, the pawl will cooperate with the ratchet 21 and rotate the ratchet 21. Correspondingly, the rotating shaft of the ratchet 21 will drive the second assembly plate 15 to rotate 180° through the second transmission belt 22, so that the neck hoop located between the two second assembly plates 15 will flip 180°, realizing the end face automatic switching function.

[0040] Please refer again Figure 4 and Figure 7 The locking mechanism comprises a ring body 28 mounted on the base 1, and two oppositely disposed recessed portions 30 are formed on the inner wall of the ring body 28; A rotating plate 23 is provided on the rotating shaft of the second assembly plate 15, and a column 25 is provided on the rotating plate 23 through a protruding block 24, a slider 26 is slidably provided on the column 25, and a pulley 29 abutting against the inner wall of the ring body 28 is rotatably installed on the slider 26; A cylindrical spring 27 is sleeved on the outer circumference of the column 25 , and two ends of the cylindrical spring 27 are respectively connected to the slider 26 and the protruding block 24 .

[0041] It should be emphasized that the elastic potential energy of the cylindrical spring 27 is relatively large. In this way, when the grinding wheel 10 processes the end face of the neck hoop, the pulley 29 is in the recessed portion 30, which can prevent the second assembly plate 15 from accidentally tilting, thereby realizing the locking function and ensuring the uniformity of the grinding wheel 10 polishing the end face of the neck hoop.

[0042] As another embodiment of the present invention, a method for processing the end surface finish of a hand mold neck hoop is also proposed, using the processing device, comprising the following steps: Step 1: placing the neck band to be processed between the two second assembly plates 15, and clamping and fixing the neck band by two sets of the stable clamping mechanisms; Step 2: After clamping is completed, the pneumatic lifting mechanism drives the horizontal plate 5 to descend until the grinding wheel 10 contacts the end surface of the neck hoop; Step 3: The radial movable mechanism works to drive the grinding wheel 10 to make a circular motion on the end surface of the neck hoop, and makes the grinding wheel 10 move intermittently along the radial direction of its circular motion to change the processing position; Step 4: After one end surface of the neck band is processed, the pneumatic lifting mechanism drives the horizontal plate 5 to rise, so that the one-way transmission mechanism is triggered, and the one-way transmission mechanism prompts the second assembly plate 15 to drive the neck band to flip half a circle; Step 5: After the end face of the neck hoop is switched, repeat the above steps 2 and 5 to complete the process.

[0043] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0044] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
