DETAILED DESCRIPTION

[0023] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0024] In the present disclosure, unless otherwise stated, directional words such as "top, bottom", "left, right", "up, down", "front, back" are used based on the orientation of related parts when used in combination, and specifically based on the orientation of the auxiliary mounting device when used. For example: the "bottom" of the crystal fixture is provided with a long strip of slide groove, and the "bottom" here refers to the side of the crystal fixture facing the bearing part, and when it is installed on the bearing part, it refers to the side facing the ground; and is used to drive the bearing part to move in the "up and down" direction relative to the mounting frame, and the "up and down" here refers to the direction perpendicular to the ground, that is, the height direction; and is used to drive the bearing part to move in the "left and right direction" relative to the mounting frame, and the "left and right" here refers to the left and right sides when the operator pushes the mounting frame to move; accordingly, the "front and back" in the present disclosure refer to the front and back sides when the operator pushes the mounting frame, for example, the bearing part is installed on the "front side" of two vertical parts, and the "front side" here refers to the side of the vertical part away from the operator. In the present disclosure, reference can also be made to "front and back, left and right, up and down" Figure 1 The direction of the arrow is shown in .

[0025] In the present disclosure, the terms "first", "second", etc. are used to distinguish one element from another element, and do not have order and importance. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0026] Reference Figure 1-Figure 3 The present disclosure exemplarily shows an auxiliary mounting device for a crystal fixture, wherein a long strip-shaped slide groove 110 is provided at the bottom of the crystal fixture 100, and the auxiliary mounting device comprises a mounting frame 200 with wheels 600 at the bottom, a bearing part 300 mounted on the mounting frame 200, a first driving part 400 mounted on the mounting frame 200 and used to drive the bearing part 300 to move in the up-down direction relative to the mounting frame 200, and a second driving part 500 mounted on the mounting frame 200 and used to drive the bearing part 300 to move in the left-right direction relative to the mounting frame 200. A slide bar 310 cooperating with the slide groove 110 is provided on the upper surface of the bearing part 300, so that the crystal fixture 100 can slide relative to the bearing part 300 along the length direction of the slide bar 310.

[0027] The present disclosure does not limit the specific structure of the mounting frame 200, as long as it is equipped with wheels 600 and is used to mount the bearing part 300, it mainly realizes the role of a "trolley", that is, the mounting frame 200 pushes the crystal fixture 100 mounted on the bearing part 300 to move and send it to the wire cutting device. It can include the vertical part and the horizontal part mentioned below, and the specific structure of the mounting frame 200 will be introduced below.

[0028] The bearing part 300 may be a plate-like structure, or a long arm structure, or an irregular structure, as long as it can form a protruding slide bar 310 on the surface and can be installed with the crystal fixture 100, and the present disclosure does not limit this. In addition, in some embodiments, in order to extend into the wire cutting chamber, the bearing part 300 may be constructed as a cantilever structure protruding forward, and may be provided with a positioning structure that cooperates with the entrance position of the wire cutting device.

[0029] In the embodiment of the present disclosure, the bearing part 300 may be provided with a positioning structure for cooperating with the wire cutting device, so as to ensure that after the bearing part 300 is moved into place, the crystal fixture 100 can be accurately moved to the installation position through the slide bar 310, thereby improving the installation efficiency.

[0030] Reference Figure 1-Figure 3 In the embodiment of the present disclosure, the cross section of the slide groove 110 may be a dovetail structure, and the slide bar 310 may be configured as a dovetail shape matching therewith, so as to prevent the crystal fixture 100 from being separated from the bearing portion 300. In addition, in some other embodiments, the cross sections of the slide groove 110 and the slide bar 310 may be regular rectangles.

[0031] The specific structures of the first driving part 400 and the second driving part 500 will be described below, and the present disclosure does not impose any limitation thereto, as long as they can achieve the corresponding functions.

[0032] By using the above technical solution, when it is necessary to install the crystal on the wire cutting device, the crystal can be first installed on the crystal fixture 100, and then the first driving part 400 is used to control the bearing part 300 to descend to a height convenient for installing the crystal fixture 100, and then the slide groove 110 and the slide bar 310 are used to cooperate to install the crystal fixture 100 on the bearing part 300, and then the bearing part 300 is pushed into the wire cutting device through the mounting frame 200, and the position of the crystal fixture 100 (up and down direction and left and right direction) is adjusted by the first driving part 400 and the second driving part 500 to align it with the positioning structure of the wire cutting device, and then the crystal fixture 100 is pushed into the wire cutting chamber of the wire cutting device along the length direction of the slide bar 310, and then the mounting frame 200 is withdrawn. With such a design, the operation process does not require manual long-term lifting and moving, manual alignment and installation of the crystal fixture 100 with the positioning structure of the wire cutting device, and the operator does not need to directly enter the wire cutting device, and the operation process saves time and effort, and is safe and fast.

[0033] Reference Figure 1-Figure 2In an embodiment of the present disclosure, the mounting frame 200 may include two L-shaped structural frames parallel to each other and a support plate 230 connected between the two L-shaped structural frames. The support plate 230 and the L-shaped structural frame may be made of metal material to have sufficient strength. The L-shaped structural frame may include a horizontal portion 220 and a vertical portion 210 connected to the rear end of the horizontal portion 220 and extending upward. Here, the horizontal portion 220 refers to a position that is generally parallel to the ground, and the vertical portion 210 refers to a position that is generally perpendicular to the horizontal portion 220. The support plate 230 may be connected to a position between the two horizontal portions 220 near the rear side, and the bearing portion 300 may be installed on the front side of the two vertical portions 210. The front side here refers to the entirety of the bearing portion 300 being located on the front side of the two vertical portions 210, and not all of it needs to be located on the front side. With such a design, an escape space can be formed between the two L-shaped structural frames. When the mounting frame 200 is pushed to the wire cutting device, the two horizontal parts 220 can "clamp" the outer shell of the wire cutting device from both sides, that is, the mounting frame 200 can make the bearing part 300 more fully extend into the wire cutting device (the mounting frame 200 is closer to the wire cutting device), avoiding the interference between the horizontal part 220 and the wire cutting device, resulting in the bearing part 300 being unable to extend into the opening of the wire cutting device, and thus making it impossible for the crystal fixture 100 to be aligned with the positioning structure of the wire cutting device, or causing the crystal fixture 100 to be unable to move into the cutting chamber of the wire cutting device. In addition, the space between the two vertical parts 210 can be used for operators to observe the front side situation, and for arranging related components, such as the first driving part 400 and the second driving part 500.

[0034] It should be noted that, in the embodiment of the present disclosure, the two L-shaped structural frames and the support plate 230 may be integrally formed. In addition, in some other embodiments, the two L-shaped structural frames and the support plate 230 may be welded to each other.

[0035] Reference Figure 1-Figure 2 In the embodiment of the present disclosure, the wheels 600 may include two universal wheels 601 installed on the rear side of the two vertical parts 210, and two unidirectional wheels 602 installed near the front end of the two horizontal parts 220. With such a design, when the mounting frame 200 is pushed to move, the two universal wheels 601 can be used to change direction, thereby improving the flexibility of the mounting frame 200. In addition, in some other embodiments, all wheels 600 may be universal wheels 601.

[0036] When the mounting frame 200 moves to the position and the crystal fixture 100 is aligned with the positioning structure of the wire cutting device, in order to ensure that the crystal fixture 100 can accurately slide along the slide bar 310 into the cutting chamber of the wire cutting device, in the embodiment of the present disclosure, the universal wheel 601 can be provided with a locking device. The locking device can ensure that the universal wheel 601 cannot rotate, thereby ensuring that the mounting frame 200 is stationary during the sliding process of the crystal fixture 100, thereby improving the installation rate of the crystal fixture 100.

[0037] Reference Figure 1-Figure 2 In the embodiment of the present disclosure, the mounting frame 200 may further include two handles 201 installed on the rear side surfaces of the two vertical portions 210. Specifically, the two handles 201 are respectively disposed on the rear side surfaces of the vertical portions 210 close to the upper side in the up-down direction, so that the user can control the movement of the mounting frame 200 by holding the two handles 201. In addition, in some other embodiments, the mounting frame 200 may further include a straight rod connected to the rear side surfaces of the two vertical portions 210 and extending in the left-right direction, with both ends of the straight rod respectively bent toward the vertical portions 210 and connected to the vertical portions 210, and the straight rod may play the role of the aforementioned handles 201.

[0038] The present disclosure does not limit the specific structure of the first driving unit 400. Figure 1-Figure 2 In the embodiment of the present disclosure, the auxiliary mounting device of the crystal fixture may further include an adapter 700 disposed between the two vertical parts 210, and the bearing part 300 may be mounted on the adapter 700. Among them, the first driving part 400 may include a hydraulic cylinder 410 disposed on the support plate 230, and the hydraulic cylinder 410 may be used to drive the adapter 700 to move in the up and down direction. In this design, the hydraulic cylinder 410 can drive the adapter 700 to drive the bearing part 300 installed on the adapter 700 to move in the up and down direction to complete the adjustment in the up and down direction. In addition, in some other embodiments, the first driving part 400 may also include a screw nut mechanism, a crank slider mechanism, a chain mechanism, etc., and its power may be generated by manual or motor, as long as it can achieve driving the adapter 700 to move in the up and down direction. In addition, in some other embodiments, the adapter 700 may also be disposed on the front side of the two vertical parts 210. Or part of it is located between the two vertical parts 210 and part of it extends to the front side of the two vertical parts 210.

[0039] Reference Figure 1-Figure 2In the embodiment of the present disclosure, the first driving unit 400 may further include a pressure rod 420 for controlling the lifting and lowering of the hydraulic cylinder 410, and one end of the pressure rod 420 may extend to the rear side of the vertical portion 210. With such a design, the operator can lift and lower the hydraulic cylinder 410 at any time by means of the pressure rod 420 when pushing the mounting frame 200, and the operation is convenient and quick. The lifting and lowering of the hydraulic cylinder 410 by means of the pressure rod 420 is well known to those skilled in the art, and will not be explained in detail here. For reference, the structure and working principle of the common pressure rod hydraulic cylinder on the market can be referred.

[0040] Specifically, in the embodiment of the present disclosure, in addition to the hydraulic cylinder 410, the first driving unit 400 may also include components such as a hydraulic pump, a hydraulic oil tank, and a hydraulic pipeline. The hydraulic pump is responsible for extracting the hydraulic oil from the oil tank and delivering it to the hydraulic cylinder 410 through the pipeline. The hydraulic cylinder 410 receives the hydraulic oil pressure from the hydraulic pump and converts it into mechanical energy, thereby raising or lowering the adapter 700. In the case where the first driving unit 400 has the above-mentioned pressure rod 420, its role is the same as that of the hydraulic pump, and it is also used to pump the hydraulic oil to the hydraulic cylinder 410.

[0041] It should be noted that in order to improve the lifting capacity of the hydraulic cylinder 410 and the stability of the lifting of the adapter 700, in some embodiments, the number of hydraulic cylinders 410 can be multiple and evenly supported on the lower side of the adapter 700. In this case, the lifting and lowering of multiple hydraulic cylinders 410 can be controlled by a pressure rod 420.

[0042] When the first driving part 400 is a chain mechanism, the two vertical parts 210 can be respectively provided with chains and sprockets, and the sprockets of the two vertical parts 210 can be respectively connected to the same motor to drive the sprockets on both sides to rotate synchronously when the motor is started, thereby driving the chain to move. In this case, the adapter 700 can be respectively connected to the chains on both sides to be able to move up and down with the chain. Its specific structure can refer to the common forklift fork arm lifting structure, and will not be described in detail here.

[0043] In order to ensure that the movement of the adapter 700 in the height direction is reliable and stable, and to prevent the adapter 700 from tipping forward due to excessive weight after the front end of the adapter 700 is installed with the bearing part 300 and the crystal fixture, in the embodiment of the present disclosure, the left and right ends of the adapter 700 can extend to the corresponding vertical parts 210 respectively, wherein the sides of the two vertical parts 210 facing the adapter 700 can be respectively provided with grooves 211 extending in the up-down direction, and the left and right ends of the adapter 700 are respectively provided with protrusions 701 extending into the corresponding grooves 211. By designing the matching of the grooves 211 and the protrusions 701, the movement of the adapter 700 can be guided and limited, and when the adapter 700 is subjected to a forward tipping force, the protrusions 701 and the grooves 211 can provide a certain reverse force to overcome the tipping, which can protect the auxiliary installation equipment.

[0044] In order to install the adapter 700 between the two vertical parts 210, in some embodiments, the groove can extend upward to the upper end of the vertical part 210. During installation, the adapter 700 can be installed from the upper end of the vertical part 210 so that the protrusion 701 can extend into the groove 211.

[0045] The present disclosure does not limit the specific structure of the second driving part 500. In the embodiment of the present disclosure, the second driving part 500 may include a lead screw 510 rotatably mounted on the adapter 700, the lead screw 510 extends along the left-right direction, and the bearing part 300 may be threadedly connected to the lead screw 510 so as to move along the left-right direction when the lead screw 510 rotates. With such a design, when the lead screw 510 rotates, the bearing part 300 may be driven to move along the left-right direction to adjust the position of the crystal fixture in the left-right direction.

[0046] In some embodiments, the second driving unit 500 may further include a nut (not shown in the figure), which is screwed on the lead screw 510 so as to move in the left and right directions when the lead screw 510 rotates, wherein the bearing unit 300 may be mounted on the nut (indirectly threadedly connected to the lead screw 510). In addition, in some embodiments, for example Figure 1 and Figure 2 In the illustrated embodiment, the bearing part 300 may be directly provided with a threaded hole, that is, the bearing part 300 may be directly screwed onto the lead screw 510 to drive the bearing part 300 to move in the left and right direction (directly threadedly connected to the lead screw 510 ) when the lead screw 510 rotates.

[0047] In the embodiment of the present disclosure, the lead screw 510 can be rotatably mounted on the adapter 700 through a bearing seat, so that the lead screw 510 can rotate relative to the adapter 700. The lead screw 510 can be specifically mounted on the inner side of the adapter 700 (the adapter 700 is a frame structure), or can also be mounted on the front side of the adapter 700, and the present disclosure does not limit this.

[0048] Reference Figure 1-Figure 2 In some embodiments, a guide rod 520 may be provided in the adapter 700, and the bearing part 300 may be provided with a guide hole that cooperates with the guide rod 520. In this case, in addition to playing a guiding and supporting role, the guide rod 520 can also limit the rotational movement of the bearing part 300, so that it can only move in the left and right directions under the rotation of the screw 510.

[0049] The present disclosure does not limit the specific structure of the adapter 700, which may be a frame structure or a solid seat structure, as long as it can follow the first drive unit 400 to move in the up and down directions and can provide an installation space for the second drive unit 500 (such as the lead screw 510) so that the second drive unit 500 can drive the bearing unit 300 to move in the left and right directions.

[0050] In some other embodiments, the second driving unit 500 may also be implemented by a crank slider, a hydraulic cylinder or other structures.

[0051] The present disclosure does not limit how to drive the lead screw 510 to rotate. In the embodiment of the present disclosure, the second driving part 500 may also include a rocker (not shown in the figure) connected to the shaft end of the lead screw 510 for driving the lead screw 510 to rotate. In this case, a space for installing the rocker needs to be reserved at the end of the lead screw 510. For example, the lead screw 510 can be arranged on the front side of the adapter 700. When the lead screw 510 needs to rotate, the bearing part 300 can be moved in the left and right directions by simply shaking the rocker. In addition, in some other embodiments, the lead screw 510 can also be driven to rotate by adding a motor.

[0052] In order to prevent the auxiliary mounting device from being easily overturned due to the heavy weight after the crystal fixture 100 is mounted on the bearing part 300, in the embodiment of the present disclosure, the mounting frame 200 can be made of a solid metal frame with a large mass.

[0053] In order to facilitate the understanding of this solution, its specific working process is described here, specifically:

[0054] First, the first driving part 400 drives the adapter 700 to drive the bearing part 300 to move to a height convenient for installing the crystal fixture 100, then lift the crystal fixture to the bearing part 300 and align the slide groove 110 with the slide bar 310, then push the mounting frame 200 to the vicinity of the wire cutting device through the wheel 600, drive the bearing part 300 to a mounting position slightly higher than the wire cutting device through the first driving part 400 (for example, the pressure rod 420), and then drive the lead screw 510 to rotate through the second driving part 500, for example, by shaking the rocker so that the nut drives the bearing part to move in the left and right directions to face the cutting chamber entrance of the wire cutting device, then push the mounting frame 200, push the bearing part 300 into the cutting chamber, and then slightly lower the height of the bearing part 300 to the positioning position through the first driving part 400, then fix the universal wheel 601, push the crystal fixture 100 into the cutting device through the slide bar 310 and the slide groove 110, and then withdraw the mounting frame 200.

[0055] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0056] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0057] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
