Description

Technical Field

[0001] This utility model relates to the field of processing technology for opening molds of composite floor slabs, specifically a welding fixture for opening molds of composite floor slabs. Background Technology

[0002] In the processing of composite floor slab opening molds, appropriate furniture is needed to clamp the molds to facilitate welding. Referring to the welding fixture for composite floor slab opening molds disclosed in CN221313056U, it includes a base, a first clamping mechanism, and a second clamping mechanism. By placing one set of plates between the first clamping plate and the back plate, and abutting against one side of the back plate, with the lower end of the plate in contact with the base, the plates are ensured to be perpendicular to each other during welding, avoiding misalignment. This facilitates welding and improves production efficiency. As described in the aforementioned patent, existing composite floor slab opening mold welding typically involves workers supporting the two sets of plates before welding. However, existing welding fixtures for composite floor slab opening molds usually only limit the plates in one direction, making it difficult to limit and clamp the non-moving ends of the plates in both directions without interference at the clamping ends. This easily causes unidirectional displacement of the plates, leading to misalignment. Furthermore, the device cannot promptly detect the thickness and width of the plates, easily affecting subsequent welding accuracy due to mismatched plate dimensions. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a welding fixture for the opening mold of composite floor slabs, which solves the problem of the single limiting direction of the clamping end of the device, which easily causes the plate to shift and affects subsequent welding.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a welding fixture for a composite floor slab opening mold, comprising a base, wherein a fixture assembly for welding composite floor slab opening molds is connected to the upper end of the base, the fixture assembly comprising:

[0005] The first adjusting component, installed on the base, is used for preventing and limiting the deviation of a set of plates. The first adjusting component includes a support frame installed on the base for providing support for the vertical limiting end. The support frame is connected to clamping components for clamping the front, rear, and top sides of the plate. The clamping component includes a one-way screw threaded to the middle of the support frame for adjusting the height of the vertical clamping end. The bottom of the one-way screw is rotatably connected to a limiting plate that is slidably connected to the support frame and is used to provide vertical limiting for the plate. The limiting plate is slidably connected to a set of limiting frames for horizontally clamping the plate at both ends near the inner side of the support frame. The base is rotatably connected along the Y-axis to a two-way screw that is threaded to the two sets of limiting frames and is used to adjust the distance between the two sets of limiting frames.

[0006] The frame is vertically mounted on the upper right side of the base;

[0007] The second adjusting component is installed on the upper left side of the frame to limit the movement of another set of plates.

[0008] Preferably, the clamping member further includes a first handwheel coaxially fixedly connected to the top of the one-way screw; the front and rear sides of the limiting frame are both provided with a first sliding groove that is slidably connected to the support frame; the inner sides of both sets of limiting frames are provided with a second sliding groove that is slidably connected to the limiting plate; the front sides of both sets of limiting frames are provided with a first scale bar for judging the vertical height of the limiting plate; and a detection bar for reading is installed on the front side of the limiting plate near the front side of the first scale bar.

[0009] Preferably, the clamping member further includes a vernier on the left side of the two sets of limiting frames, and the first adjusting member further includes a second scale bar for judging the distance between the two sets of limiting frames. The second scale bar is disposed on the base and located below the two sets of verniers. The base is provided with a moving groove along the Y-axis near the lower side of the two sets of limiting frames. The end of the base near the moving groove is equipped with a slide rod that is slidably connected to the bottom ends of the two sets of limiting frames respectively. The front side of the base is provided with a positioning member for adjusting the rotation of the bidirectional screw.

[0010] Preferably, the positioning component includes a second handwheel installed on the front side of the bidirectional screw, a threaded rod is threadedly connected to the upper side of the base near the second handwheel, an array of actuating rods for rotating the threaded rod is installed on the top edge of the threaded rod, a positioning pin for locking the second handwheel is fixedly connected to the bottom of the threaded rod, and a plurality of positioning grooves are provided on the side of the second handwheel corresponding to the positioning pin.

[0011] Preferably, the lower side of the frame is provided with a slot for providing space for welding, and the internal structure of the second adjusting member is the same as that of the first adjusting member, which is used to prevent deviation and limit the position of the other set of plates on both sides.

[0012] Preferably, the base has a square groove near the second scale bar to protect the second scale bar, and the second scale bar is disposed in the square groove.

[0013] This utility model provides a welding fixture for the opening mold of composite floor slabs. Compared with the prior art, it has the following advantages:

[0014] (1) The welding fixture for the opening mold of the composite floor slab, by setting two sets of adjusting components in the device, allows the support frame, one-way screw, first handwheel, limit plate, detection strip, limit frame and first scale strip to cooperate with each other to achieve vertical limiting of the horizontal plate and timely obtain the plate thickness. The second handwheel, two-way screw, two sets of limit frames, vernier and second scale strip cooperate with each other to achieve limiting clamping of the front and rear ends of the horizontal plate and obtain the plate width. Under the condition that the clamping ends do not affect each other, the plate can be limited in two directions, improving the anti-deviation accuracy. Since the internal structure of the second adjusting component is the same as that of the first adjusting component, the second adjusting component cooperates with the frame to achieve limiting clamping and reading of the vertical plate, so that the two sets of plates can be accurately spliced, which helps to accurately weld in the future.

[0015] (2) The welding fixture for the opening mold of the composite floor slab has a square groove on the base. This setting, through the height difference, avoids scratching the scale end caused by the friction between the second scale strip and the plate when the plate slides along the upper surface of the base, reduces the impact on the plate width detection, and extends the service life of the second scale strip.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] refer to Figure 1-4 This utility model provides the following two technical solutions:

[0023] First embodiment: A welding fixture for the opening mold of a composite floor slab, comprising a base 1, wherein a fixture assembly for welding the opening mold of the composite floor slab is connected to the upper end of the base 1, the fixture assembly comprising:

[0024] The first adjusting component 2 is installed on the base 1 for preventing and limiting the deviation of a set of plates. The first adjusting component 2 includes a support frame 21 installed on the base 1 for providing support for the vertical limiting end. The support frame 21 is connected to a clamping component 22 for clamping the front, rear and top sides of the plate. The clamping component 22 includes a one-way screw 221 threadedly connected to the middle of the support frame 21 for adjusting the height of the vertical clamping end. The bottom of the one-way screw 221 is rotatably connected to a limiting plate 223 that is slidably connected to the support frame 21 and is used to provide vertical limiting for the plate. The limiting plate 223 is slidably connected to a set of limiting frames 225 for horizontally clamping the plate at both ends near the inner side of the support frame 21. The base 1 is rotatably connected along the Y-axis to a two-way screw 228 that is threadedly connected to the two sets of limiting frames 225 and is used to adjust the distance between the two sets of limiting frames 225.

[0025] The frame 3 is vertically mounted on the upper right side of the base 1; the second adjusting component 4 is mounted on the upper left side of the frame 3 for limiting the position of another set of plates; the clamping component 22 also includes a first handwheel 222 coaxially fixedly connected to the top of the one-way screw 221; the front and rear sides of the limiting frame 225 are vertically provided with a first sliding groove that slides through the support frame 21; the inner sides of both sets of limiting frames 225 are provided with a second sliding groove that slides through the limiting plate 223; the front of both sets of limiting frames 225 is provided with a first scale bar 226 for judging the vertical height of the limiting plate 223; the front of the limiting plate 223 is close to the first scale bar. A detection strip 224 for reading is installed on the front side of the strip 226; the clamping member 22 also includes a vernier 227 disposed on the left side of the two sets of limit frames 225; the first adjusting member 2 also includes a second scale strip 23 for judging the distance between the two sets of limit frames 225; the second scale strip 23 is disposed on the base 1 and located below the two sets of vernier 227; the base 1 is provided with a moving groove along the Y-axis near the lower side of the two sets of limit frames 225; a slide rod is installed on the base 1 near the moving groove end, which is slidably connected to the bottom ends of the two sets of limit frames 225 respectively; a positioning member 229 for adjusting the rotation of the bidirectional screw 228 is provided on the front side of the base 1;

[0026] Positioning component 229 includes a second handwheel 2294 installed on the front side of the bidirectional screw 228. A threaded rod 2291 is threadedly connected to the upper side of the base 1 near the second handwheel 2294. An array of levers 2292 for rotating the threaded rod 2291 are installed on the top edge of the threaded rod 2291. A positioning pin 2293 for locking the second handwheel 2294 is fixedly connected to the bottom of the threaded rod 2291. Several positioning grooves are provided on the side of the second handwheel 2294 corresponding to the positioning pins 2293. A slot is provided on the lower side of the frame 3 to provide space for welding. The internal structure of the second adjusting component 4 is the same as that of the first adjusting component 2, used for anti-deviation and limiting treatment of the two sides of another set of plates. The support frame 21, unidirectional screw 221, first handwheel 222, limiting plate 223, detection strip 224, and limiting... The frame 225 and the first scale bar 226 work together to achieve vertical positioning of the horizontal plate and timely obtain the plate thickness. The second handwheel 2294, the bidirectional screw 228, the two sets of limiting frames 225, the vernier 227, and the second scale bar 23 work together to achieve limiting clamping of the front and rear ends of the horizontal plate and obtain the plate width. Since the internal structure of the second adjusting component 4 is the same as that of the first adjusting component 2, the second adjusting component 4 works with the frame 3 to achieve limiting clamping and reading processing of the vertical plate, so that the two sets of plates can be accurately spliced. After the second handwheel 2294 has rotated, the threaded rod 2291 is rotated by the toggle lever 2292, so that the threaded rod 2291 drives the positioning pin 2293 to be inserted into the positioning groove on the side of the second handwheel 2294, thereby locking the second handwheel 2294.

[0027] The main difference between the second implementation method and the first implementation method is that:

[0028] The base 1 has a square groove near the second scale bar 23 to protect the second scale bar 23. The second scale bar 23 is set in the square groove, and the top of the second scale bar 23 is lower than the height of the upper surface of the base 1. This setting, through the height difference, avoids scratching the scale end due to friction between the second scale bar 23 and the plate when the plate slides along the upper surface of the base 1 for adjustment.

[0029] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0030] In use, the user places the plate to be welded on the upper side of the base 1, so that the plate passes through the first adjusting piece 2 and the end to be welded faces the frame 3. The user then rotates the second handwheel 2294. The second handwheel 2294 drives the two sets of limiting frames 225 to move along the base 1 towards the front and rear sides of the plate through the bidirectional screw 228. After the two sets of limiting frames 225 clamp the front and rear sides of the plate respectively, the user stops rotating the second handwheel 2294. During this process, the limiting frames 225 drive the vernier 227 to move. The width of the plate is obtained by the cooperation of the two sets of vernier 227 and the second scale bar 23.

[0031] Rotate the first handwheel 222, which drives the one-way screw 221 to rotate. The one-way screw 221 drives the limiting plate 223 and the detection strip 224 to slide vertically along the inner side of the two sets of limiting frames 225 and the support frame 21. After the bottom of the limiting plate 223 is in contact with the upper surface of the plate, the plate thickness is obtained by the cooperation of the detection strip 224 and the first scale strip 226, thus achieving the vertical and horizontal limiting of the plate. The other set of plates is placed between the frame 3 and the second adjusting member 4. The base 1 provides support for the bottom of the modified set of plates. Repeat the above limiting operation to achieve the limiting of both sides of the set of plates. Fine-tune the position of the two sets of plates so that the ends of the two sets of plates to be welded are spliced. Weld the two sets of plates through the slot on the lower side of the frame 3.
