[0001] This utility model relates to the field of positioning fixture technology, and in particular to a slide rail type clamp assembly with an adjustable structure. Background Technology

[0002] CNC is a type of computer numerical control machine tool. A computer numerical control machine tool is an automated machine tool equipped with a program control system. CNC machining refers to machining carried out using CNC machine tool machining equipment. This control system can logically process programs with control codes or other symbolic instructions, decode them, and thus enable the machine tool to move and machine parts. Therefore, CNC machining has the advantages of stable machining quality, high machining precision, ability to machine complex surfaces, and high machining efficiency.

[0003] Currently, with the increasing maturity of laser welding technology, handheld laser welding equipment is being widely used in various industries. In the production of laser guns, the galvanometer cavity is generally machined from aluminum profiles using a high-precision and high-efficiency CNC lathe. Due to the small size of the galvanometer cavity, in order to ensure processing and handling efficiency, there are existing jig structures that can support multiple components at once. However, the clamping position of the existing jig is fixed, and when the position of the clamping position needs to be adjusted, another jig assembly must be replaced. This greatly extends the processing time and is not conducive to improving production efficiency. Therefore, it is necessary to design a new jig to meet daily production needs. Utility Model Content

Obviously, the described embodiments are some, but not all, embodiments of this utility model. 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.

[0027] The preferred embodiment of this utility model is a slide rail type clamp assembly with an adjustable structure, such as... Figure 1-5 As shown, the system includes a rectangular base plate 10, a slide rail 20 disposed on the upper surface of the base plate 10, two parallel side plates 30 fixed to the upper surface of the base plate 10 at both ends of the slide rail 20, a plurality of clamping seats 40 slidably disposed on the slide rail 20, and an adjustment module 50 for adjusting the distance between adjacent clamping seats 40. The two side plates 30 are fixedly connected to each other by tie rods 60. Two slide rails 20 are arranged side-by-side, and the two slide rails 20 and the plurality of clamping seats 40 form a unit. This unit has two sets arranged side-by-side on the base plate 10 to further improve processing efficiency. Furthermore, each clamping seat 40 has a clamping part at both its left and right ends for clamping and positioning the workpiece 200. Before processing, the workpiece 200 is positioned... The 0 is placed between two clamping parts for initial positioning. Specifically, the adjustment module 50 includes an adjustment shaft 51 parallel to the slide rail 20 and a turntable 52 for adjusting the rotation of the adjustment shaft 51. The adjustment shaft 51 is located below the clamping seat 40 and its two ends are rotatably connected to the two side upright plates 30 through bearings. Multiple movable seats 70 are threaded on the adjustment shaft 51 corresponding to multiple clamping seats 40. The movable seats 70 are fixed to the bottom of the clamping seat 40. When it is necessary to adjust the position of multiple clamping seats 40, rotating the turntable 52 causes the adjustment shaft 51 to move the movable seats 70, thereby realizing the synchronous adjustment of the position of multiple clamping seats 40. The operation is simple and convenient, greatly reducing the operation time caused by changing another set of fixtures.

[0028] In this embodiment, the clamping seat 40 includes a rectangular fixing plate 41 arranged in the front-to-back direction, and a clamping seat 42 disposed on the upper surface of the fixing plate 41. The clamping seat 42 is specifically a cuboid structure with its bottom four sides aligned with the four sides of the fixing plate 41. The two ends of the fixing plate 41 are respectively provided with two sliders 80 that are slidably connected to the two slide rails 20. The adjusting shaft 51 is located below the fixing plate 41. The upper ends of the left and right side walls of the clamping seat 42 are recessed with positioning steps 421 for positioning the workpiece 200, which are used to position the left and right ends of the workpiece 200. Specifically, the front and rear ends of the clamping seat 42 are detachably provided with mounting seats 90 by bolts. The upper surface of the mounting seat 90 is provided with a plane, and vertical ribs 100 are provided on the plane along the left and right directions. One end of the vertical rib 100 is aligned with the edge of the positioning step 421. The positioning step 421, the plane, and the vertical rib 100 form a clamping part. The two vertical ribs 100 can further improve the positioning stability of the workpiece 200 and ensure that it does not shift in the front-to-back direction.

[0029] In this embodiment, the vertical rib 100 is provided with an adjustment screw hole corresponding to the positioning step 421 on its longitudinal end, so as to facilitate the installation of positioning bolts for pressing the workpiece 200 from the front and back, and further enhance the clamping stability of the workpiece 200; in addition, in the actual processing, hydraulic columns are generally provided through the outer walls of the two side walls to assist in pressing the multiple clamping seats 40 towards the middle.

[0030] In this embodiment, the adjusting shaft 51 includes multiple sub-shafts 511 corresponding one-to-one with multiple movable seats 70, and a connecting assembly 512 connecting two adjacent sub-shafts 511; wherein, the connecting assembly 512 includes an outer sleeve a1 coaxially sleeved on the sub-shaft 511, the inner sidewall of the outer sleeve a1 is provided with a first protrusion 110 and a second protrusion 120 at both ends, and the sidewalls of two adjacent sub-shafts 511 are provided with a positioning groove 130 and an annular clearance groove 140 corresponding to the first protrusion 110 and the second protrusion 120, respectively. The positioning groove 130 is elongated and axially arranged, and the annular clearance groove 140 is coaxial with the sub-shaft 511. The sidewall of the annular clearance groove 140 away from the positioning groove 130 is axially provided with a slot 150 for the second protrusion 120 to be inserted. In the initial state, the second protrusion 120 is located in the slot 150. In step 50, when the turntable 52 rotates, the rotational torque can be transmitted sequentially to the last sub-shaft 511 through the adjacent sub-shaft 511 and the outer sleeve a1, thereby synchronously driving all the clamping seats 40 to move together, so as to realize the position adjustment of all the clamping seats 40; when only the distance between two adjacent clamping seats 40 needs to be adjusted, the outer sleeve a1 is slid in the opposite direction so that the second protrusion 120 enters the annular relief groove 140. At this time, the connection between the two adjacent sub-shafts 511 is broken. Further rotation of the outer sleeve a1 can drive the corresponding sub-shaft 511 to rotate, thereby moving the clamping seat above the rotating sub-shaft 511, and finally realizing the left and right position adjustment of the clamping seat 40. After the adjustment is completed, sliding the outer sleeve a1 to reset can realize the connection of the two sub-shafts 511.

[0031] In order to ensure the stability of the transmission of the sub-shaft 511 in the initial state, the outer sleeve a1 and the sub-shaft 511 maintain damped sliding. Alternatively, a spring can be provided on the end of the outer sleeve a1 away from the annular relief groove 140 and fitted onto the sub-shaft 511, or a tension spring can be provided on the other end, so as to achieve the purpose of automatic reset after adjustment and maintaining the connection between the two sub-shafts 511 in the initial state.

[0032] In this embodiment, the first protrusion 110 is radially detachably connected to the outer sleeve a1. One end of the back ion shaft 511 of the first protrusion 110 extends out of the outer sleeve a1. The first protrusion 110 and the outer sleeve a1 can be threaded or tightly fitted and separable interference fit. Preferably, this solution uses a threaded connection, while the first protrusion 110 is implemented with a bolt to facilitate disassembly and installation using tools.

[0033] In this embodiment, the outer sleeve a1 includes a first half-shell a11 and a second half-shell a12 that surrounds it to form a cylindrical structure. The first half-shell a11 and the second half-shell a12 are hinged together and open in the circumferential direction. The ends of the first half-shell a11 and the second half-shell a12 that are away from the hinge are detachably connected, which facilitates installation and disassembly. The specific connection method between the two can be bolted, snap-fitted, or directly connected by drilling holes and inserting wires, or directly fixed with a hoop to ensure that the first half-shell a11 and the second half-shell a12 do not easily open during rotation.

[0034] In this embodiment, the connecting component 512 further includes a positioning shaft a2 and a matching movable groove a3. On the adjacent ends of two adjacent sub-shafts 511, one is coaxially provided with a positioning shaft a2 and the other is provided with a movable groove a3. Through the cooperation of the positioning shaft a2 and the movable groove a3, the stability of the connection between the two sub-shafts 511 can be further enhanced, and the concentricity of the two sub-shafts 511 can be guaranteed.

[0035] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
