Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a welding equipment with a positioning structure. Background Technology

[0002] The stainless steel cup body formed by stamping needs to be sealed by welding to make it into a thermos. The purpose of welding is mainly to ensure the airtightness of the cup body and prevent water and air leakage. Therefore, the welding process and precision requirements are high.

[0003] When welding thermos cups, they need to be fixed first. However, traditional welding equipment generally has the problem of low positioning accuracy when processing positioning components for products such as thermos cups. This may lead to poor welding process and problems such as water leakage and air leakage in the long-term use of thermos cups. Based on this, a welding equipment with a positioning structure is proposed. Utility Model Content

[0004] To solve the technical problem of positioning during welding of thermos cups, this utility model provides a welding device with a positioning structure.

[0005] This utility model is achieved using the following technical solution: a welding device with a positioning structure, including a welding worktable, an mounting plate fixedly connected to the upper side of the welding worktable, a first limiting platform fixedly connected to the upper side of the mounting plate, a plurality of first slots provided on the first limiting platform, the plurality of first slots being arranged in a circumferential array, a first block slidably connected to the inner side of each first slot, a clamping arm fixedly connected to each first block, a clamping block fixedly connected to the upper side of each clamping arm, the plurality of clamping blocks being used to limit and fix the thermos cup body from the side, a clamping block driving mechanism being provided inside the first limiting platform to make the plurality of clamping blocks approach or separate from each other, and a laser welding mechanism being provided above the clamping blocks.

[0006] As a further improvement to the above solution, the clamping block driving mechanism includes a second clamping block that is fixedly connected to the side of the first clamping block near the center of the first limiting platform. The multiple second clamping blocks are arranged in a circumferential array, and a wedge-shaped pushing mechanism is provided at the center of the circumferential area formed by the multiple second clamping blocks.

[0007] As a further improvement to the above solution, the wedge-shaped pushing mechanism includes a second limiting platform that is slidably connected to the inner side of the first limiting platform. The second limiting platform is provided with multiple second slots, which are opened at an angle in the vertical direction. The multiple second slots are distributed in a circumferential array. Each second block is slidably connected to the inner side of each second slot. The lower side of the mounting plate is provided with a lifting drive mechanism that causes the second limiting platform to slide up and down reciprocally along the inner side of the first limiting platform.

[0008] As a further improvement to the above solution, the lifting drive mechanism includes a servo motor fixedly connected to the lower side of the mounting plate. The output end of the servo motor is fixedly connected to a threaded rod, which extends upward and is threadedly connected to the second limiting platform. A thermos cup placement mechanism is provided at the upper end of the threaded rod.

[0009] As a further improvement to the above solution, the thermos cup placement mechanism includes a placement plate rotatably connected to the upper end of the threaded rod, and the upper side of the placement plate is used to place the blank thermos cup to be welded.

[0010] As a further improvement to the above solution, the laser welding mechanism includes a laser welding unit fixedly connected to the upper side of the welding worktable.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. The No. 2 clamping block and the No. 2 clamping slot of this utility model are driven by a wedge-shaped push. When the No. 2 limiting platform rises or falls, it will drive the No. 1 clamping block to move forward or backward inside the No. 1 clamping slot, so as to achieve the opening and closing effect of the clamping block. The sliding motion mode inside the groove has the advantages of high precision, accurate positioning and small system error.

[0013] 2. This utility model uses the sliding of the first card block inside the first card slot and the sliding of the second card block inside the second card slot to drive the clamping blocks to open and close, which has the advantages of wear resistance and long service life.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] Example:

[0023] Please combine Figure 1 - Figure 5 This embodiment of a welding device with a positioning structure includes a welding worktable 1. A mounting plate 2 is fixedly connected to the upper side of the welding worktable 1. A first limiting platform 3 is fixedly connected to the upper side of the mounting plate 2. The first limiting platform 3 has a hollow frustum-shaped structure and three first slots 14 are T-shaped slots arranged in a circular array. A first locking block 10 is slidably connected to the inner side of each first slot 14. It has a T-shaped clamping block structure. Each clamping block 10 is fixedly connected to a clamping arm 9. The clamping arm 9 is a straight plate structure. Each clamping arm 9 is fixedly connected to a clamping block 8 on its upper side. The clamping block 8 is a fan-shaped frustum structure. Its inner wall can switch with the outer surface of the thermos cup. It is a detachable design. The three clamping blocks 8 are used to limit and fix the thermos cup body from the side. The first limiting platform 3 is equipped with a clamping block driving mechanism that makes the multiple clamping blocks 8 approach or separate from each other. A laser welding mechanism is set above the clamping blocks 8.

[0024] Please combine Figure 4 As shown, the clamping block driving mechanism includes a second clamping block 13 that is fixedly connected to one of the three first clamping blocks 10 near the center of the first limiting platform 3. The second clamping block 13 has an inclined structure design. Please refer to... Figure 5 As shown, the second card block 13 and the second card slot 11 are tilted and matched to form a wedge-shaped pushing relationship. The three second card blocks 13 are arranged in a circular array, and a wedge-shaped pushing mechanism is set at the center of the circular area formed by the three second card blocks 13.

[0025] Please combine Figure 4 As shown, the wedge-shaped pushing mechanism includes a second limiting platform 12 that is slidably connected inside the first limiting platform 3. The second limiting platform 12 has a frustum-shaped structure with an internal threaded sleeve at its center. Three second-level slots 11 are provided on the second limiting platform 12. The internal structure of the second-level slots 11 is described in conjunction with... Figure 5As shown, the second slot 11 is opened at an angle in the vertical direction, and the three second slots 11 are arranged in a circular array. Each second card block 13 is slidably connected to the inside of each second slot 11. The lower side of the mounting plate 2 is provided with a lifting drive mechanism that allows the second limiting platform 12 to slide up and down along the inside of the first limiting platform 3.

[0026] Please combine Figure 4 As shown, the lifting drive mechanism includes a servo motor 15 fixedly connected to the lower side of the mounting plate 2. The servo motor 15 can rotate forward and reverse, driving the second limit platform 12 to rise or fall. The output end of the servo motor 15 is fixedly connected to a threaded rod 4, which extends upward and is threadedly connected to the second limit platform 12. The upper end of the threaded rod 4 is provided with a thermos cup placement mechanism.

[0027] Please combine Figure 4 As shown, the thermos cup placement mechanism includes a placement plate 5 rotatably connected to the upper end of the threaded rod 4. The upper side of the placement plate 5 is used to place the blank thermos cup to be welded. When multiple clamping blocks 8 position and clamp the thermos cup, the placement plate 5 and the threaded rod 4 rotate.

[0028] Please combine Figure 1 As shown in the figure, the laser welding mechanism includes a laser welding unit 7 fixedly connected to the upper side of the welding worktable 1. The laser welding unit 7 has a vertical movement function unit and a forward and backward movement function unit, which makes it easy to approach the thermos cup body.

[0029] The implementation principle of a welding device with a positioning structure in this application embodiment is as follows: The thermos cup body to be welded is placed on the upper side of the placement plate 5. The servo motor 15 is started, which drives the threaded rod 4 to rotate for a certain period of time. Since the second card block 13 is limited and locked by the second card slot 11 in the second limiting platform 12, when the threaded rod 4, which is threadedly connected to the second limiting platform 12, rotates, the second limiting platform 12 descends. Since the second card block 13 and the second card slot 11 opened in the second limiting platform 12 are wedge-shaped structures, the descent of the second limiting platform 12 will inevitably pull the second card block 13 closer to each other, thereby driving the first card block 10 distributed in the circle to move closer to each other. The clamping arm 9 drives the clamping blocks 8 to move closer to each other to form a clamping and positioning effect.

[0030] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
