[0071] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0072] The terms "first," "second," etc., used in this embodiment of the invention are used to distinguish similar objects, not to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that the embodiments of the invention can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same class, without limiting the number of objects; for example, the first object can be one or more. Furthermore, in this embodiment of the invention, "or" indicates at least one of the connected objects. For example, "A or B" covers three scenarios: Scenario 1: including A but not B; Scenario 2: including B but not A; Scenario 3: including both A and B. The character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0073] In the technical solutions of this utility model embodiment, terms such as "connection," "coupling," or "linked" are not limited to physical or mechanical connections, but can include electrical connections.

[0074] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0075] This utility model embodiment provides a workbench for a tire changing and mounting machine; see [link / reference]. Figure 1 As shown, the workbench of the tire changer includes:

[0076] The first slide rail 1 extends in the left-right direction;

[0077] The base 2 is mounted on the first slide rail 1 and can slide along the first slide rail 1;

[0078] Mounting column 3 is provided on base 2 and extends in the vertical direction. Mounting column 3 has a second slide rail 31 extending in the vertical direction on one side in the front-back direction.

[0079] The sliding seat 4 is disposed on the second slide rail 31 and can slide along the second slide rail 31;

[0080] Tire mounting and dismounting mechanism 5 is located on sliding seat 4.

[0081] When tire removal is required, the user uses a clamping device to hold the wheel hub (on which the tire to be removed is mounted) and then operates the base 2 to slide along the first slide rail 1 to the wheel hub. Further, the user operates the sliding seat 4 to move the tire removal mechanism 5 to the junction of the wheel hub and the tire, and then uses the tire removal mechanism 5 to remove the tire from the wheel hub.

[0082] When tire loading is required, the user uses a clamping device to hold the wheel hub. Then, the user operates the base 2 to slide along the first slide rail 1 to the wheel hub. Further, the user moves the tire to the wheel hub, and then operates the sliding seat 4 to move the tire loading / unloading mechanism 5 between the wheel hub and the tire, using the tire loading / unloading mechanism 5 to load the tire onto the wheel hub.

[0083] In this embodiment of the utility model, the workbench includes a first slide rail 1 extending in the left-right direction; a base 2 disposed on the first slide rail 1 and capable of sliding along the first slide rail 1; a mounting column 3 disposed on the base 2 and extending in the up-down direction, and the mounting column 3 having a second slide rail 31 extending in the up-down direction on one side in the front-back direction; a sliding seat 4 disposed on the second slide rail 31 and capable of sliding along the second slide rail 31; and a tire removal and installation mechanism 5 disposed on the sliding seat 4, so that the tire removal and installation mechanism 5 in this embodiment of the utility model can realize displacement in the left-right and up-down directions, improving the convenience of tire removal and installation operations and helping to improve the efficiency of tire removal and installation operations.

[0084] In some embodiments of this utility model, optionally, the tire removal and installation mechanism 5, see [link to relevant documentation]. Figure 1 , 3 As shown in 4 and 5, it includes:

[0085] The fixed frame 51 is rotatably mounted on the sliding seat 4 about the rotating shaft a extending in the vertical direction;

[0086] The mounting tube 52 has one end connected to the fixing bracket 51 and the other end provided with a mounting plate 53;

[0087] The push rod shaft 54 ​​is located in the cavity of the mounting tube 52 and can slide along the length of the mounting tube 52;

[0088] Drive assembly 55 is used to drive push rod shaft 54 ​​to slide along the length direction of mounting tube 52;

[0089] The first end of the push rod shaft 54 ​​located on the side of the mounting plate 53 is provided with a tire removal hook assembly, and the second end of the push rod shaft 54 ​​located on the side of the fixing frame 51 is connected to the drive assembly 55 in a driving manner.

[0090] When tire removal or installation is required, the user can operate the fixing frame 51 to rotate around the pivot a in a direction away from the sliding seat 4, so as to facilitate the tire to be removed or installed into the removal / installation station. After the tire to be removed or installed enters the removal / installation station, the user can operate the fixing frame 51 to rotate around the pivot a in a direction closer to the sliding seat 4 until the fixing frame 51 is in the working position against the sliding seat 4. In this case, the user can further use the tire removal / installation mechanism 5 to remove or install the tire.

[0091] In some optional embodiments, the tire mounting / removing mechanism 5 further includes a locking mechanism for locking the mounting bracket 51 in the working position. For an example, see [link to documentation]. Figure 1 and Figure 2 As shown, the locking mechanism includes a locking hook 512 rotatably mounted on a fixed frame 51 about a pivot b in the vertical direction, and a boss 513 on a sliding seat 4. When the fixed frame 51 is in the working position against the sliding seat 4, the user can operate the locking hook 512 to rotate about the pivot b towards the sliding seat 4 until the locking hook 512 engages with the boss 513, thus locking the fixed frame 51 in the working position. It should be noted that there are numerous examples of locking mechanisms in the art, too many to list. This application... Figure 1 and Figure 2 The locking mechanism shown is merely exemplary and not restrictive. In practical applications, those skilled in the art, guided by the teachings of this application, can create many other locking mechanisms without departing from the spirit and scope of the claims, all of which fall within the protection scope of this application.

[0092] In this embodiment of the invention, when the position of the tire removal hook assembly needs to be adjusted, the user can operate the drive assembly 55 to drive the push rod shaft 54 ​​to slide along the length direction of the mounting tube 52, thereby displacing the tire removal hook assembly. Based on the workbench of this embodiment of the invention, the user can adjust the position of the tire removal hook assembly relative to the contact point between the tire and the wheel rim according to the actual tire removal needs (e.g., different tire sizes and different wheel rim sizes), thereby improving the efficiency of tire removal operations.

[0093] In some embodiments of this utility model, optionally, see [reference needed]. Figures 3 to 5 As shown, the push rod shaft 54 ​​includes a first shaft segment 541 and a second shaft segment 542. The first end is located in the first shaft segment 541 and the second end is located in the second shaft segment 542. The first shaft segment 541 can rotate relative to the second shaft segment 542 about the axis of the mounting tube 52.

[0094] The mounting plate 53 can rotate around the axis of the mounting tube 52;

[0095] Tire hook assembly includes:

[0096] The tire removal hook 56 has a hook body 561, a support part 562 and an adapter part 563, and the support part 562 is located between the hook body 561 and the adapter part 563 in the length direction of the tire removal hook 56; the support part 562 is rotatably connected to the mounting plate 53 via a first pin 101.

[0097] The first connecting rod 57 has one end rotatably connected to the adapter 563 via the second pin 102, and the other end rotatably connected to the first end via the third pin 103.

[0098] The axes of the first pin 101, the second pin 102, and the third pin 103 are parallel to each other.

[0099] In this embodiment of the invention, when it is necessary to adjust the tilt angle of the tire removal hook 56 in the left-right direction, taking increasing the tilt angle to the left as an example, see [reference needed]. Figure 3 and Figure 4 As shown, the user-operable drive assembly 55 drives the push rod shaft 54 ​​to slide along the mounting tube 52 toward the fixing bracket 51, causing the tire removal hook 56 to rotate clockwise (from the perspective of viewing from front to back) around the first pin shaft 101, increasing the tilt angle of the tire removal hook 56 to the left. Increasing the tilt angle to the right is based on the same principle as increasing the tilt angle to the left, only in the opposite direction, and will not be described further here.

[0100] In this embodiment of the invention, the first shaft segment 541 can rotate relative to the second shaft segment 542 around the axis of the mounting tube 52. One end of the first connecting rod 57 is rotatably connected to the adapter 563 via the second pin 102, and the other end is rotatably connected to the first end via the third pin 103. Furthermore, the support part 562 is rotatably connected to the mounting plate 53 via the first pin 101. Thus, the user can operate the mounting plate 53 to rotate around the axis of the mounting tube 52, thereby driving the tire removal hook 56 to rotate around the axis of the mounting tube 52. This allows for convenient and flexible adjustment of the tilt angle of the tire removal hook 56 in the front-back direction, improving the convenience and efficiency of tire removal operations in this embodiment of the invention.

[0101] Understandably, the adjustment of the tilt angle of the tire removal hook 56 in the front-back direction will not interfere with the adjustment of the tilt angle of the tire removal hook 56 in the left-right direction. The two can be implemented independently, further improving the convenience of tire removal operations and increasing the efficiency of tire removal operations in this embodiment of the present invention.

[0102] In some embodiments of this utility model, optionally, see [reference needed]. Figure 1 , Figure 3 and Figure 5 As shown, the workbench of the tire changer also includes: a tire separation pressure plate 6 and a tire mounting assembly 7.

[0103] The tire separation pressure plate 6 and the tire mounting assembly 7 are disposed on the peripheral outer wall of the mounting plate 53 at intervals.

[0104] In practical applications, when switching tools according to the needs of tire removal and installation, the user can operate the mounting plate 53 to rotate around the axis of the mounting tube 52, thereby switching any one of the tools—the tire removal hook assembly, the tire separation pressure plate 6, and the tire installation assembly 7—to be opposite the tire being removed or installed (which has entered the removal / installation station). Specifically, in this embodiment of the invention, the tool is switched to face downwards, making tool switching convenient and quick. There is no need to remove the tire from the tire changer and then load it into the removal / installation station after switching tools; this embodiment of the invention improves tire removal and installation efficiency.

[0105] In some optional embodiments, the tire removal hook assembly (tire removal hook 56), tire separation pressure plate 6, and tire mounting assembly 7 all extend radially along the mounting plate 53. Each of the three is orthographically projected relative to the plane d containing the opening of the mounting plate 53. The angle between the orthographic projections of any two adjacent components is approximately 120°, and the sum of all three angles between any two components is 360°. In some optional embodiments, "approximately" may mean an error range of 10°, i.e., 110° ≤ the angle value ≤ 130°. This arrangement effectively avoids interference between the tire removal hook assembly, tire separation pressure plate 6, and tire mounting assembly 7, reducing the failure rate of this embodiment.

[0106] In some embodiments of this utility model, optionally, see [reference needed]. Figures 3 to 5 As shown, the drive component 55 includes:

[0107] The drive cylinder 551 is fixedly mounted on the fixed frame 51 and has a piston rod 5511 that can slide and extend along the inner cavity of the cylinder.

[0108] Support base 552 is mounted on fixed frame 51;

[0109] The second link 553 has a first slot 501 and a second slot 502 at its two ends along its length, and both the first slot 501 and the second slot 502 extend along the length of the second link 553; the second link 553 also has a connecting hole 503 located between the first slot 501 and the second slot 502.

[0110] By providing a fourth pin 104 between the first slot 501 and the second end, the second connecting rod 553 is rotatably connected to the second end; and the fourth pin 104 can both rotate relative to the first slot 501 and slide relative to the first slot 501 along the length direction of the first slot 501.

[0111] By providing a fifth pin 105 between the second slot 502 and the piston rod 5511, the second connecting rod 553 is rotatably connected to the piston rod 5511; and the fifth pin 105 can both rotate relative to the second slot 502 and slide relative to the second slot 502 along the length direction of the second slot 502.

[0112] By setting a sixth pin 106 between the connecting hole 503 and the support base 552, the second connecting rod 553 is rotatably connected to the support base 552;

[0113] The axes of the fourth pin 104, the fifth pin 105, and the sixth pin 106 are parallel to each other.

[0114] When it is necessary to adjust the tilt angle of the tire hook 56 in the left and right directions, taking increasing the tilt angle to the left as an example, see [link to relevant documentation]. Figure 3 and Figure 4 As shown, the user can operate the drive assembly 55 to slide and retract the piston rod 5511 into the inner cavity 551a of the drive cylinder 551, causing the second connecting rod 553 to rotate clockwise (from a front-to-back viewpoint) around the sixth pin 106. The second connecting rod 553 pulls the push rod shaft 54 ​​along the mounting tube 52 towards the fixing bracket 51, causing the tire removal hook 56 to rotate clockwise (from a front-to-back viewpoint) around the first pin 101, increasing the tilt angle of the tire removal hook 56 to the left. Increasing the tilt angle to the right is based on the same principle as increasing the tilt angle to the left, only in the opposite direction, and will not be described further here.

[0115] In this embodiment of the invention, the drive component 55 has a simple structure and high reliability during long-term use.

[0116] In some embodiments of this utility model, optionally, see [reference needed]. Figure 1 As shown, drive cylinder 551 is a hydraulic cylinder;

[0117] The mounting column 3 is equipped with a hydraulic oil pump 81 and a first controller 82 on the other side in the front-rear direction;

[0118] The hydraulic oil pump 81 has a hydraulic oil inlet / outlet port (not shown in the figure) connected to the hydraulic oil inlet / outlet port of the hydraulic cylinder. The hydraulic oil pump 81 is used to push the piston rod 5511 to extend or pull the piston rod 5511 to retract by adding hydraulic oil under the control of the extension signal or retraction signal.

[0119] Specifically, see Figures 3 to 5 As shown, the hydraulic oil inlet and outlet ports of the hydraulic cylinder include: a first inlet / outlet port 100 and a second inlet / outlet port 200. The first inlet / outlet port 100 and the second inlet / outlet port 200 are spaced apart on the drive cylinder 551, one on the left and one on the right, and both are connected to the inner cavity 551a of the cylinder body.

[0120] When the hydraulic pump 81 receives an extension signal, it injects hydraulic oil into the cylinder cavity 551a through the first inlet / outlet port 100. The injected hydraulic oil enters the cylinder cavity 551a located to the left of the piston 300, pushing the piston 300 to the right, thereby driving the piston rod 5511 to extend. During the extension of the piston rod 5511, the rightward movement of the piston 300 compresses the hydraulic oil in the cylinder cavity 551a located to the right of the piston 300, causing this portion of the hydraulic oil to flow back to the hydraulic pump 81 through the second inlet / outlet port 200.

[0121] When the hydraulic pump 81 receives a contraction signal, it injects hydraulic oil into the cylinder cavity 551a through the second inlet / outlet port 200. The injected hydraulic oil enters the cylinder cavity 551a located to the right of the piston 300, pushing the piston 300 to the left, thereby driving the piston rod 5511 to contract. During the contraction of the piston rod 5511, the leftward-moving piston 300 compresses the hydraulic oil in the cylinder cavity 551a located to the left of the piston 300, causing this portion of the hydraulic oil to flow back to the hydraulic pump 81 through the first inlet / outlet port 100.

[0122] It should be noted that the hydraulic oil pump 81 adds hydraulic oil to the cylinder cavity 551a through the first inlet / outlet port 100 or through the second inlet / outlet port 200. The switching between the two inlet / outlet ports is not achieved by a program, but by a directional valve, and is the subject of protection of a utility model patent.

[0123] The first control port of the first controller 82 is electrically connected to the hydraulic oil pump 81. The first control port is also connected to the interactive terminal associated with the user. The first control port is used to receive the extension signal or retraction signal sent by the interactive terminal and forward the extension signal or retraction signal to the hydraulic oil pump 81.

[0124] In this embodiment of the invention, hydraulic oil is added to the hydraulic cylinder, causing the piston rod 5511 to slide out of the inner cavity 551a of the drive cylinder 551. Hydraulic oil is then withdrawn from the hydraulic cylinder, causing the piston rod 5511 to slide and retract into the inner cavity 551a of the drive cylinder 551.

[0125] In some embodiments of this utility model, optionally, see [reference needed]. Figure 1 As shown, drive cylinder 551 is a pneumatic cylinder;

[0126] The mounting column 3 is equipped with an air pump 91 and a second controller 92 on the other side in the front-rear direction;

[0127] The gas inlet / outlet port of the air pump 91 (not shown in the figure) is connected to the gas inlet / outlet port of the cylinder (not shown in the figure). The air pump 91 is used to charge or exhaust the cylinder under the control of a charging signal or an exhaust signal.
