Description

Technical Field

[0001] This utility model relates to the field of band saw carriage technology, and in particular to a wood clamping device for automatic woodworking carriages. Background Technology

[0002] Woodworking automatic trolleys (such as band saw trolleys, multi-blade saw trolleys, etc.) are automated devices used for efficient and precise transportation and fixing of wood. Their core function is to clamp the wood and move it stably during processing.

[0003] Existing technologies have the following problems:

[0004] Extensive research revealed that existing wood clamping devices are typically installed on platforms that directly support the wood and are driven by pneumatic or hydraulic power. These methods of clamping wood rely on external energy, have complex structures, and high maintenance costs, making them unsuitable for the basic clamping needs of small and medium-sized wood processing.

[0005] To address these shortcomings, we proposed a wood clamping device for automatic woodworking carriages. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a wood clamping device for automatic woodworking trolleys.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a wood clamping device for an automatic woodworking carriage, comprising a support platform, guide rods symmetrically distributed on both sides of the top surface of the support platform, and guide blocks slidably connected to each guide rod, a support frame welded between the two guide blocks, and a movable gripper fixedly installed on one side of the support frame, a fixed gripper corresponding to the movable gripper provided on one side of the top surface of the support platform, a support plate welded to one side of the top surface of the support platform, and a screw used in conjunction with the surface of the support plate, with a handle installed at one end of the screw, and a rotating component installed at the other end of the screw, the rotating component abutting against the support frame, and a return spring fixedly installed between the support frame and the support plate.

[0008] Preferably, the opposing surfaces of the fixed gripper and the movable gripper are each bonded with a hook and loop fastener, and the opposing surfaces of the two hook and loop fasteners are each bonded with a loop fastener, and the other side surface of the two loop fasteners is fitted with an anti-slip pad.

[0009] Preferably, the guide rod is arranged along the width direction of the support platform.

[0010] Preferably, the fixed gripper and the movable gripper are used in combination.

[0011] Preferably, the anti-slip pad has the same surface area as the fixed gripper and the movable gripper.

[0012] Preferably, the length of the support frame is greater than the length of the movable gripper.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, the user pre-pushes the movable gripper to the approximate position according to the width of the wood, then places the wood between the fixed gripper and the movable gripper, and then manually rotates the screw to push the movable gripper closer to the fixed gripper until the wood is pressed. When released, the screw is rotated in the opposite direction, and the spring pulls the movable gripper back to its original position, away from the fixed gripper. It is driven on only one side, avoiding complex linkage mechanisms, reducing costs, simplifying operation, and making it suitable for non-precision scenarios. It eliminates the need for a synchronization mechanism, double screws or linkage components, and significantly reduces material and processing costs.

[0015] 2. This utility model increases friction and protects the wood surface by setting a removable and replaceable anti-slip pad, reducing the risk of damage to the wood surface. It is also convenient and labor-saving to replace, with low maintenance costs and strong practicality, making it worthy of promotion. Attached Figure Description

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0025] Please refer to Figure 1-4 A wood clamping device for an automatic woodworking carriage includes a support platform 1. Guide rods 2 are symmetrically distributed on both sides of the top surface of the support platform 1, and guide blocks 3 are slidably connected to each of the two guide rods 2. A support frame 4 is welded between the two guide blocks 3, and a movable gripper 5 is fixedly installed on one side of the support frame 4. A fixed gripper 6 corresponding to the movable gripper 5 is provided on one side of the top surface of the support platform 1. A support plate 7 is welded to one side of the top surface of the support platform 1, and a screw 8 is fitted on the surface of the support plate 7. A handle 9 is installed at one end of the screw 8, and a rotating part 10 is installed at the other end of the screw 8. The rotating part 10 abuts against the support frame 4. A return spring 11 is fixedly installed between the support frame 4 and the support plate 7.

[0026] In this embodiment: the opposite sides of the fixed gripper 6 and the movable gripper 5 are both bonded with hook and loop fasteners 12, and the opposite sides of the two hook and loop fasteners 12 are both bonded with hook and loop fasteners 13, and the other side surface of the two hook and loop fasteners 13 is equipped with an anti-slip pad 14.

[0027] Specifically, the user pre-pushes the movable jaw 5 to its approximate position based on the width of the wood, then places the wood between the fixed jaw 5 and the movable jaw 6. Next, the user manually rotates the screw 8 to push the movable jaw 5 closer to the fixed jaw 6 until the wood is clamped. To release, the user rotates the screw 8 in the opposite direction, and the return spring 11 pulls the movable jaw 5 back to its original position, moving it away from the fixed jaw 6. This single-sided drive avoids complex linkage mechanisms, reduces costs, simplifies operation, and is suitable for non-precision applications. It eliminates the need for synchronization mechanisms, double threaded rods, or linkage components, significantly reducing material and processing costs. The removable and replaceable anti-slip pad 14 increases friction and protects the wood surface, reducing the risk of damage. It is also easy and labor-saving to replace, with low maintenance costs and strong practicality, making it worthy of promotion. This design, by returning to basic mechanical principles (screw 8 + guide rod 2 + return spring 11), significantly simplifies the structure and reduces costs while ensuring functionality. Its core value lies in: practicality: meeting the basic clamping needs of small and medium-sized wood processing; universality: suitable for environments with limited resources, promoting the inclusiveness of technology; sustainability: low energy consumption, easy maintenance, and in line with the concept of green manufacturing.

[0028] In this implementation scheme: the guide rod 2 is set along the width direction of the bearing platform 1.

[0029] Specifically, this allows the movable gripper 5 to move in the width direction of the support platform 1, thereby clamping the wood.

[0030] In this implementation scheme: the fixed gripper 6 and the movable gripper 5 are used together.

[0031] Specifically, when used together, the two can clamp the wood.

[0032] In this implementation scheme: the anti-slip pad 14 has the same surface area as the fixed gripper 6 and the movable gripper 5.

[0033] Specifically, this prevents the wood from directly contacting the fixed gripper 6 and the movable gripper 5, thus avoiding damage to the surface of the wood.

[0034] In this implementation scheme: the length of the support frame 4 is greater than the length of the movable gripper 5.

[0035] Specifically, ensure that the movable gripper 5 can be installed on the support frame 4.

[0036] Working principle: During use, the user pre-pushes the movable jaw 5 to the approximate position according to the width of the wood, then places the wood between the fixed jaw 5 and the movable jaw 6. Next, the user manually rotates the screw 8 to push the movable jaw 5 closer to the fixed jaw 6 until the wood is clamped. To release, the user rotates the screw 8 in the opposite direction, and the return spring 11 pulls the movable jaw 5 back to its original position, away from the fixed jaw 6. This single-sided drive avoids complex linkage mechanisms, reduces costs, simplifies operation, and is suitable for non-precision applications. It eliminates the need for a synchronization mechanism, double threaded rods, or linkage components, significantly reducing material and processing costs. By incorporating a removable and replaceable anti-slip pad 14, friction is increased and the wood surface is protected, reducing the risk of damage. Replacement is convenient and labor-saving, maintenance costs are low, and practicality is strong, making it worthy of promotion. This design, by returning to basic mechanical principles (screw 8 + guide rod 2 + return spring 11), significantly simplifies the structure and reduces costs while ensuring functionality. Its core value lies in: practicality: meeting the basic clamping needs of small and medium-sized wood processing; universality: suitable for resource-limited environments, promoting the widespread adoption of technology; sustainability: low energy consumption, easy maintenance, and in line with the concept of green manufacturing.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
