Abstract
Description
Technical Field
[0001] This utility model relates to the field of foam processing technology, and in particular to a clamping device for foam processing. Background Technology
[0002] Foam materials, such as polystyrene foam (EPS) and polyurethane foam (PU), are widely used in many fields, including construction, packaging, transportation, and home appliance manufacturing, due to their excellent properties such as light weight, heat insulation, sound insulation, and good cushioning. With the continued development of these downstream industries, the foam processing industry is also experiencing vigorous growth, with the market size constantly expanding and the requirements for the quantity and quality of foam products increasing daily.
[0003] Foam processing involves multiple steps, including cutting, carving, bonding, and coating. To ensure processing accuracy and product quality, these steps typically require stable and reliable clamping of the foam material to prevent movement, shaking, or deformation during processing, thus guaranteeing smooth operation and accurate results. However, due to the diversity of foam material shapes, sizes, and textures, different processing steps have varying requirements for clamping methods and forces. Existing clamping equipment mostly uses fixed fixtures with low flexibility, only adapting to the clamping needs of foam materials with specific shapes, sizes, or processing methods. For example, some clamping equipment is only suitable for clamping regular rectangular foam boards, and cannot effectively clamp irregularly shaped foam products; or some clamping equipment can only meet the clamping requirements of specific processing steps, requiring replacement when the processing steps change. This not only increases equipment procurement costs but also reduces production efficiency. Therefore, this application provides a clamping device for foam processing to meet these needs. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a clamping device for foam processing to solve the problem that existing foam clamps are difficult to effectively clamp foam materials of different shapes and sizes.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] A clamping device for foam processing includes a clamping table, a slide rail on the top of the clamping table, a pair of vertical arms on the slide rail, the pair of vertical arms being able to move horizontally along the length of the slide rail, and a drive mechanism on the slide rail for driving the pair of vertical arms to move closer together and separate; a crossbar is provided on the vertical arm, and an electric push rod is mounted on the end of the crossbar away from the vertical arm, and a clamp is provided on the telescopic end of the electric push rod.
[0007] Optionally, the slide rail is located on one side of the top of the clamping platform and is distributed along the length of the clamping platform. A pair of slide seats are slidably mounted on the slide rail. The vertical arm is vertically fixed on the slide seats, and the horizontal bar is horizontally fixed on the top of the vertical arm facing the middle of the clamping platform.
[0008] Optionally, the clamp includes a clamping rod fixed to the telescopic end of the electric push rod and a clamping block fixed to the end of the clamping rod.
[0009] Optionally, a reinforcing plate is fixed between the side wall of the vertical arm and the upper surface of the slide block, and a reinforcing strip is obliquely fixed between the side wall of the vertical arm and the bottom of the crossbar.
[0010] Optionally, the clamping platform has side plates that are bent vertically downwards at both ends, and mounting holes are provided at the bottom of the side plates.
[0011] Optionally, a pair of sliders are slidably embedded in the slide rail, and a guide groove is provided on the upper surface of the slide rail. The pair of sliders pass through the guide groove and are respectively connected to a pair of slide blocks.
[0012] Optionally, the driving mechanism includes a bidirectional lead screw rotatably mounted in the slide rail and a motor mounted at the end of the slide rail for driving the bidirectional lead screw to rotate, and a pair of sliders are symmetrically threaded onto the bidirectional lead screw.
[0013] Optionally, a pull rod is movably inserted inside the crossbar, and an end block is connected to one end of the pull rod away from the vertical arm. The electric push rod is mounted on the end block, and the other end of the pull rod passes through the vertical arm and is threaded with a sleeve.
[0014] Optionally, a positioning plate is fixed to the end of the crossbar away from the vertical arm. The positioning plate has multiple positioning holes arranged in a ring. A positioning post is provided on the side of the end block facing the crossbar, and the positioning post is inserted into the positioning hole.
[0015] Optionally, the two sides of the slide block are bent downwards and slidably fit against the side wall of the slide rail.
[0016] Compared with the prior art, this utility model has at least the following beneficial effects:
[0017] In the above scheme, the structure of the pull rod moving through the crossbar allows the end block to be rotated to adjust the tilt angle of the electric push rod after the end block is loosened and pulled to disengage the positioning pin from the positioning hole. The end block is then pushed to insert the positioning pin into the corresponding positioning hole on the positioning plate. Tightening the end block uses the pull rod to force the end block to abut against the positioning plate, thus positioning the tilt angle of the electric push rod. When the electric push rod is adjusted to a vertical or tilted state, a pair of electric push rods push the chuck down, which can fix the foam workpiece on the clamping table. When the electric push rod is adjusted to a horizontal state, a pair of electric push rods push the chuck to move towards the opposite side, which can horizontally clamp the foam workpiece above the clamping table. Through the setting of the slide rail and drive mechanism, a pair of vertical arms and crossbars can be driven to move closer or apart. The distance between the pair of electric push rods can be adjusted. Combined with the adjustment of the rotation angle of the electric push rods, foam workpieces of different sizes and structures can be clamped and fixed, which has high flexibility and adaptability.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of this utility model provides a clamping device for foam processing, including a clamping table 1. A slide rail 2 is provided on the top of the clamping table 1, and a pair of vertical arms 4 are provided on the slide rail 2. The pair of vertical arms 4 can move horizontally along the length direction of the slide rail 2. A drive mechanism is provided on the slide rail 2 for driving the pair of vertical arms 4 to move closer together and separate. A crossbar 5 is provided on the vertical arm 4. An electric push rod 6 is mounted on the end of the crossbar 5 away from the vertical arm 4. A chuck 7 is provided on the telescopic end of the electric push rod 6. The chuck 7 includes a clamping rod 15 fixed to the telescopic end of the electric push rod 6 and a clamping block 16 fixed to the end of the clamping rod 15. With this structure, the electric push rod 6 is activated to push the clamping rod 15 and the clamping block 16 down, which can clamp and fix the foam workpiece on the clamping table 1 to facilitate the processing operation of the foam workpiece. The drive mechanism drives the pair of vertical arms 4 to move closer together or separate, which can adjust the distance between the pair of electric push rods 6 to adapt to the clamping and fixing of foam workpieces of different sizes.
[0033] like Figure 1 , Figure 3 and Figure 4 As shown, the slide rail 2 is located on one side of the top of the clamping platform 1, and the slide rail 2 is distributed along the length of the clamping platform 1. A pair of slide seats 3 are slidably fitted on the slide rail 2. The vertical arm 4 is vertically fixed on the slide seat 3, and the horizontal bar 5 is horizontally fixed on the top of the vertical arm 4 facing the middle of the clamping platform 1. This facilitates the clamping and fixing of foam on the clamping platform 1 for processing operations. A reinforcing plate 17 is fixed between the side wall of the vertical arm 4 and the upper surface of the slide seat 3, and a reinforcing strip 14 is obliquely fixed between the side wall of the vertical arm 4 and the bottom of the horizontal bar 5. The reinforcing plate 17 and the reinforcing strip 14 are used to improve the structural strength of the vertical arm 4 and the horizontal bar 5. Side plates 8 are vertically bent downward at both ends of the clamping platform 1. The bottom end of the side plate 8 is provided with mounting holes 9. The two sides of the slide seat 3 are bent downward and slide against the side wall of the slide rail 2.
[0034] like Figure 2 , Figure 3 and Figure 4As shown, a pair of sliders 13 are slidably embedded in the slide rail 2. A guide groove 10 is provided on the upper surface of the slide rail 2. The pair of sliders 13 pass through the guide groove 10 and are respectively connected to a pair of slide blocks 3. The driving mechanism includes a bidirectional lead screw 12 rotatably installed in the slide rail 2 and a motor 11 installed at the end of the slide rail 2 for driving the bidirectional lead screw 12 to rotate. The pair of sliders 13 are symmetrically threaded on the bidirectional lead screw 12. When the motor 11 is started, it drives the bidirectional lead screw 12 to rotate, causing the pair of sliders 13 to move closer or further apart, thereby driving a pair of vertical arms 4 and horizontal bars 5 to move closer or separate, thus achieving the purpose of adjusting the distance between a pair of electric push rods 6.
[0035] like Figure 1 , Figure 3 and Figure 5 As shown, a pull rod 22 is movably inserted into the crossbar 5. One end of the pull rod 22, away from the vertical arm 4, is connected to an end block 20. An electric push rod 6 is mounted on the end block 20. The other end of the pull rod 22 passes through the vertical arm 4 and is threaded with a threaded sleeve 23. A positioning plate 18 is fixed to the end of the crossbar 5 away from the vertical arm 4. Multiple positioning holes 19 are provided on the positioning plate 18, arranged in a ring. A positioning post 21 is provided on the side of the end block 20 facing the crossbar 5. The positioning post 21 is inserted into the positioning hole 19. Through this structural design, after loosening the threaded sleeve 23 and pulling the end block 20 to disengage the positioning post 21 from the positioning hole 19, the end block 20 can be rotated to adjust the electric push rod 6. By tilting the end block 20, the positioning pin 21 is inserted into the corresponding positioning hole 19 on the positioning plate 18. Tightening the screw sleeve 23 forces the end block 20 to abut against the positioning plate 18 using the pull rod 22. This allows for positioning of the tilt angle of the electric push rod 6. When the electric push rod 6 is adjusted to a vertical or tilted state, activating a pair of electric push rods 6 pushes the chuck 7 to fix the foam workpiece on the clamping table 1. When the electric push rod 6 is adjusted to a horizontal state, a pair of electric push rods 6 push the chuck 7 to move towards the opposite side, which can horizontally clamp the foam workpiece above the clamping table 1. This allows for clamping and fixing of the foam workpiece at multiple angles, suitable for clamping and fixing foam workpieces of different structural shapes.
[0036] The workflow of the technical solution provided by this utility model is as follows:
[0037] In use, after loosening the sleeve 23 and pulling the end block 20 to disengage the positioning pin 21 from the positioning hole 19, the end block 20 can be rotated to adjust the tilt angle of the electric push rod 6. Pushing the end block 20 will cause the positioning pin 21 to engage with the corresponding positioning hole 19 on the positioning plate 18. Tightening the sleeve 23 will force the end block 20 to abut against the positioning plate 18 using the pull rod 22. This allows for positioning of the tilt angle of the electric push rod 6. When the electric push rod 6 is adjusted to a vertical or tilted position, activating a pair of electric push rods 6 will push the clamping rod 15 and clamping block 16 downwards, thus fixing the foam workpiece in the clamping position. On platform 1, when the electric push rods 6 are adjusted to a horizontal position, a pair of electric push rods 6 push the clamping rods 15 and clamping blocks 16 to move towards opposite sides, which can horizontally clamp the foam workpiece above the clamping platform 1. Furthermore, the start motor 11 drives the bidirectional lead screw 12 to rotate, causing a pair of sliders 13 to move closer or separate, and causing a pair of vertical arms 4 and horizontal bars 5 to move closer or separate. The distance between the pair of electric push rods 6 can be adjusted. Combined with the adjustment of the rotation angle of the electric push rods 6, foam workpieces of different sizes and structures can be clamped and fixed, which has high flexibility and adaptability.
