[0048] 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.

[0049] Please see Figures 1-4 The rear box horizontal clamp proposed in this embodiment includes a clamp body 1, a clamping member 2 and a bracket 3.

[0050] like Figure 1 As shown, the fixture body 1 includes a support base 11, a vertical plate 12, and a slide rail 13. The support base 11 is used for supporting and positioning the fixture. The vertical plate 12 is vertically mounted on the support base and is used to install the rear box. The slide rail 13 is mounted on the support base 11. The clamping member 2 is mounted on the vertical plate 12 and is used for clamping and positioning the rear box. The bracket 3 is horizontally mounted on the slide rail 13 of the support base 11 and is slidably connected to it. It is used to transport the rear box placed on the bracket 3 to the vertical plate 12 for clamping and positioning.

[0051] Specifically, the clamping component 2 is mounted on the upright plate 12, and its main function is to clamp and position the rear box. In practical applications, the clamping component 2 can take various forms, such as hydraulic clamping devices or mechanical clamping devices. When the rear box is transported to the upright plate 12, the clamping component 2 firmly clamps the rear box onto the upright plate 12 through its clamping force, ensuring that the rear box will not shift or vibrate during processing, thereby guaranteeing processing accuracy.

[0052] The bracket 3 is one of the key components of this fixture. It is horizontally mounted on the slide rail 13 of the support base 11 and slidably connected to the slide rail 13. The main function of the bracket 3 is to transport the rear box placed on it to the upright plate 12 for clamping and positioning. When clamping the rear box, first place the rear box on the bracket 3, and then push or pull the bracket 3 to slide it along the slide rail 13 to transport the rear box to the upright plate 12. This horizontal clamping method, compared with the traditional vertical plate clamping method, greatly improves the convenience of clamping, reduces labor intensity, and also reduces the risk of processing errors caused by improper clamping.

[0053] In some embodiments, such as Figures 2-3 As shown, the bracket 3 includes a tray 31 and a slider 32. The tray 31 is horizontally arranged on the upper side of the slide rail 13 for placing the rear box. The slider 32 is fixedly arranged on the lower side of the tray 31 and slidably connected to the slide rail 13. The clamp body 1 also includes a stop 14, which is arranged at the end of the slide rail 13 for limiting the slider 32.

[0054] Specifically, the structure of the bracket 3 and the fixture body 1 have been further refined. The design of the tray 31 changes the traditional vertical clamping method to a horizontal clamping method, greatly improving clamping convenience, reducing labor intensity, and minimizing the risk of processing errors due to improper clamping. The sliding mechanism of the slider 32, which cooperates with the slide rail 13, ensures that the bracket 3 can slide smoothly and steadily along the slide rail 13, thereby ensuring a more stable and accurate transport process for the rear box. Of course, this sliding method is not the only option.

[0055] Meanwhile, a stop 14 is provided at the end of the slide rail 13 of the fixture body 1. The function of the stop 14 is to limit the slider 32. When the bracket 3 slides along the slide rail 13, the stop 14 can effectively prevent the slider 32 from sliding out of the slide rail 13, thereby preventing the bracket 3 from detaching from the fixture body 1 and improving the safety and reliability of the fixture.

[0056] In some embodiments, such as Figures 2-3 As shown, the bracket 3 also includes a support member 33 and a limiting member 34. The support member 33 is located on the upper side of the tray 31 corresponding to the bottom of the rear box, and is used to support the rear box. The limiting member 34 is located on the upper side of the tray 31 corresponding to the outer periphery of the bottom of the rear box, and is used to limit the outer periphery of the bottom of the rear box.

[0057] Specifically, the support member 33 is located on the upper side of the pallet 31 corresponding to the bottom of the rear box, and is used to support the rear box. The shape and height of the support member 33 can be adjusted according to the structure of the rear box to provide stable support for the rear box while ensuring that it corresponds to the installation position of the upright plate 12. With the setting of the limiting member 34, the position of the rear box on the pallet 31 can be restricted to prevent the rear box from shifting or shaking during the conveying process. This ensures that the position of the rear box placed on the bracket 3 is consistent with the clamping position when it is conveyed to the upright plate 12, which facilitates the accurate and stable clamping of the rear box on the upright plate 12 after the rear box is conveyed, and further improves the clamping accuracy and stability of the fixture.

[0058] The support member 33 includes a support block 331 and an adjusting nut 332. The support block 331 is fixedly mounted on the upper side of the support plate 31. The adjusting nut 332 is threadedly connected to the top of the support block 331 and is used to adjust the support height.

[0059] Specifically, the support block 331 is fixedly installed on the upper side of the pallet 31. Its shape and size should match the bottom of the rear box to ensure stable and reliable support for the rear box. The adjusting nut 332 is threaded onto the top of the support block 331. By rotating the adjusting nut 332, the height of the support block 331 can be adjusted to match the clamping position of the upright plate 12. At the same time, it can adapt to rear boxes of different heights or shapes, improving the versatility and flexibility of the clamp, meeting the clamping requirements of various specifications of rear boxes, and further expanding the applicability and practicality of the clamp.

[0060] In some embodiments, such as Figures 3-4 As shown, a rear box horizontal clamping fixture also includes a positioning structure 4 and a positioning block 5. The positioning structure 4 is located at the bottom of the bracket 3; the positioning block 5 is located on the support base 11 and is correspondingly arranged with the positioning structure 4. A positioning hole 501 is opened on the side of the positioning block 5 corresponding to the positioning structure 4 for positioning the positioning structure 4.

[0061] Specifically, a positioning structure 4 and a positioning block 5 are added to the fixture. During use, when the bracket 3 slides to the designated position, the positioning structure 4 engages with the positioning hole 501 on the positioning block 5 to achieve precise positioning of the bracket 3. The positioning hole 501 can be located where the bracket 3 reaches the mounting point of the upright plate 12, or when the bracket 3 is pulled out to the outside. The positioning hole 501 is located where the bracket 3 reaches the mounting point of the upright plate 12 to ensure accurate stopping when the bracket 3 is pulled out to the outside or reaches the upright plate 12. The positioning hole 501 is located when the bracket 3 is pulled out to the outside to provide a stable and precise reference when the rear box is placed on the bracket 3 and when the rear box is clamped, thereby ensuring machining accuracy and fixture reliability, and further improving fixture performance and machining quality.

[0062] In some embodiments, such as Figures 3-4 As shown, the positioning structure 4 includes a V-shaped member 41, a pull rod 42, an insert rod 43, a first guide block 44, and a second guide block 45. The V-shaped member 41 is rotatably mounted on the bottom of the bracket 3 via a pin. One end of the pull rod 42 is hinged to one end of the V-shaped member 41, and the other end of the pull rod 42 extends to the outside of the bracket 3. One end of the insert rod 43 is hinged to the other end of the V-shaped member 41, and the other end of the insert rod 43 is positioned towards the positioning hole 501 for insertion into the positioning hole 501. The first guide block 44 is located at the bottom of the bracket 3 corresponding to the pull rod 42, and the pull rod 42 passes through the first guide block 44 and is slidably connected to it. The second guide block 45 is located at the bottom of the bracket 3 corresponding to the insert rod 43, and the insert rod 43 passes through the second guide block 45 and is slidably connected to it.

[0063] Specifically, during use, pulling the pull rod 42, in conjunction with the first guide block 44 located at the pull rod 42 and the second guide block 45 located at the insertion rod 43, drives the V-shaped part 41 to rotate around the pin, thereby allowing the insertion rod 43 to insert into or exit the positioning hole 501, achieving the positioning or unlocking of the bracket 3. This facilitates positioning and unlocking while ensuring convenient operation and accurate positioning, effectively improving the positioning accuracy and reliability of the fixture and further optimizing its performance.

[0064] In some embodiments, such as Figure 4 As shown, the insertion rod 43 includes a rod body 431, an insertion head 432, and a spring 433. One end of the rod body 431 is hinged to the other end of the V-shaped member 41, and the other end of the rod body 431 is positioned towards the positioning hole 501. The insertion head 432 is located at the end of the rod body 431 facing the positioning hole 501, and the outer diameter of the insertion head 432 is larger than that of the rod body 431. The spring 433 is sleeved on the rod body 431.

[0065] Specifically, the structure of the insertion rod 43 is further refined. This design allows the insertion head 432 of the insertion rod 43 to better insert into the positioning hole 501, improving the stability and reliability of the positioning. A spring 433 is sleeved on the rod body 431. The function of the spring 433 is to provide a certain elastic buffering force when the insertion rod 43 is inserted into the positioning hole 501, and to automatically reset when the insertion rod 43 is withdrawn from the positioning hole 501. This makes the insertion and withdrawal of the insertion rod 43 smoother, further improving the operational convenience and reliability of the positioning structure 4.

[0066] In some embodiments, such as Figure 4 As shown, the positioning structure 4 includes a handle 46 and a pull plate 47. The handle 46 is located on the side wall of the bracket 3 and corresponds to one end of the pull rod 42 that extends to the outside of the bracket 3. The pull plate 47 is located at one end of the pull rod 42 that extends to the outside of the bracket 3 and is used to assist in pulling the pull rod 42.

[0067] Specifically, the handle 46 and the lever 42 are designed so that the operator can simultaneously grasp or release the lever 42 and the handle 46 to insert or remove the insertion rod 43 from the positioning hole 501. This makes it easier for the operator to pull the lever 42, further improving the ease of operation of the positioning structure 4, reducing the difficulty of operation, making the use of the fixture more user-friendly, and further optimizing the overall performance and user experience of the fixture.
