Description

Technical Field

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

[0002] A woodworking band saw truck is a machine used for processing wood.

[0003] A search revealed a woodworking band saw carriage (publication number: CN219466388U), comprising a carriage body and two brackets slidably mounted on the carriage body. A bidirectional screw is rotatably mounted inside the carriage body. A first motor for driving the bidirectional screw is fixedly mounted at one end of the carriage body. The two brackets are threaded onto both ends of the bidirectional screw. A transverse screw is rotatably mounted inside each bracket. A second motor for driving the transverse screw is fixedly mounted at one end of each bracket. A limit frame is threaded onto the transverse screw. A vertical screw is rotatably mounted inside the limit frame. A third motor for driving the vertical screw is fixedly mounted at the top of the limit frame. A clamping plate is threaded onto the vertical screw.

[0004] In existing technologies, two clamping plates are mainly driven by a lead screw to adjust the locking position of the wood. However, the number of clamping plates is fixed, which makes the number of fixing points on the wood unadjustable. Secondly, the two clamping plates move synchronously, which has certain drawbacks in actual production and processing. For example, it is difficult to adjust the clamping position of only one clamping plate on the wood. There is room for optimization.

[0005] Therefore, we propose a woodworking band saw carriage. Utility Model Content

[0006] The present invention mainly solves the technical problems of fixed number of clamping plates and unfavorable adjustment synchronization in actual processing, and provides a woodworking band saw carriage.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a woodworking band saw carriage, comprising:

[0008] The sports car body has two parallel guide rails fixedly installed on its top. A slide table is slidably mounted on the guide rails, and a crossbeam is fixedly installed on one side of the slide table.

[0009] A limiting structure is detachably mounted on the crossbeam for limiting the wood. The limiting structure includes a first card seat, an adjusting screw, a flipping block, and locking teeth. The flipping block is rotatably connected to the first card seat, and the flipping block and the first card seat together form a C-shaped locking ring. The locking ring can slide radially along the crossbeam. Several locking teeth are fixedly provided at the bottom of the first card seat, and the locking teeth can engage with the crossbeam. The adjusting screw is threadedly connected to the first card seat.

[0010] In a preferred embodiment of this utility model, the crossbeam is a rectangular rod, and the bottom of the crossbeam is evenly provided with teeth, which are used in conjunction with the locking teeth.

[0011] In a preferred embodiment of this utility model, the first card holder is an L-shaped folding rod, the flipping block is rotatably disposed at one end of the first card holder, and the distance between the top and bottom surfaces of the first card holder is greater than the height of the crossbeam.

[0012] In a preferred embodiment of this utility model, the flipping block is a rectangular prism, the length of the flipping block is less than the height of the first card seat, a rotating shaft is fixedly installed on one side of the flipping block, the first card seat has a shaft hole, and the rotating shaft is rotatably installed in the shaft hole.

[0013] In a preferred embodiment of this utility model, an ear plate is fixedly installed on one side of the first card holder, and a nut is fixedly provided on the ear plate. The adjusting screw is threadedly connected to the nut.

[0014] As a preferred embodiment of this utility model, the limiting structure further includes a base plate and claws. The base plate is rotatably disposed at the lower end of the adjusting screw. Several claws are fixedly installed on the bottom of the base plate. The claws are symmetrical in pairs and form a group. The two claws in the same group are distributed in an inward V-shape.

[0015] In a preferred embodiment of this utility model, a limiting block is fixedly installed at the bottom of the slide table. The limiting block is slidably connected to the guide rail, and a lead screw is rotatably connected to the guide rail. The lead screw is threadedly connected to the limiting block.

[0016] This utility model provides a woodworking band saw carriage. It has the following beneficial effects:

[0017] 1. This woodworking band saw carriage, by rotating the adjusting screw, applies downward pressure to the wood at its lower end. Simultaneously, the wood exerts a reaction force on the adjusting screw, causing the first clamping seat to move upward. The teeth at the bottom of the first clamping seat engage with the teeth at the bottom of the crossbeam, thereby achieving radial limiting of the first clamping seat. At this time, the first clamping seat and the adjusting screw can stably provide downward pressure to the wood to achieve limiting. When the adjusting screw is loosened, the adjusting screw separates from the wood, and the first clamping seat falls under the action of gravity. The bottom surface of the flipping block separates from the bottom of the crossbeam, and the upper end of the first clamping seat fits against the top surface of the crossbeam. The first clamping seat can be pushed to adjust the downward pressure position of the adjusting screw on the wood. It has the characteristics of flexible adjustment and self-locking, making it convenient to adjust the position of the adjusting screw according to the cutting position.

[0018] 2. This woodworking band saw carriage rotates a flip block, causing its lower end to rotate above a first clamping seat, thus exposing the notch of the first clamping seat. By aligning the crossbeam with the notch of the first clamping seat and inserting it, and then flipping the flip block back to its original position, the first clamping seat and the flip block form a C-shaped ring. The number of clamping rings formed by the first clamping seat and the flip block can be adjusted by changing the number of clamping rings on the crossbeam, thus adjusting the number of fixed positions of the wood. Adding or removing the number of clamping rings is simple and easy to operate, providing better flexibility.

[0019] 3. This type of woodworking band saw carriage, by rotating the adjusting screw, pushes the base plate down, and the wood is limited by multiple claws on the bottom of the base plate. The symmetrically distributed claws can inhibit the rolling and slippage of the wood, which is conducive to the precise cutting of the wood. Attached Figure Description

[0026] A type of woodworking band saw trolley, such as Figure 1 and Figure 2 As shown, it includes:

[0027] The sports car body 10 has two parallel guide rails 11 fixedly installed on its top. A slide table 12 is slidably mounted on the guide rails 11, and a crossbeam 13 is fixedly installed on one side of the slide table 12.

[0028] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a limiting structure is detachably mounted on the crossbeam 13 for limiting the wood. The limiting structure includes a first locking seat 20, an adjusting screw 21, a flipping block 22, and locking teeth 23. The flipping block 22 is rotatably connected to the first locking seat 20, and the flipping block 22 and the first locking seat 20 together form a C-shaped locking ring that can slide radially along the crossbeam 13. Several locking teeth 23 are fixedly provided at the bottom of the first locking seat 20, and the locking teeth 23 can engage with the crossbeam 13. The adjusting screw 21 is threadedly connected to the first locking seat 20. The crossbeam 13 is a rectangular rod, and the bottom of the crossbeam 13 is evenly open. The device is equipped with teeth that cooperate with the locking teeth 23. The first locking seat 20 is an L-shaped folding rod. The flipping block 22 is rotatably set at one end of the first locking seat 20. The distance between the top and bottom surfaces of the first locking seat 20 is greater than the height of the crossbeam 13. The flipping block 22 is a rectangular prism. The length of the flipping block 22 is less than the height of the first locking seat 20. A rotating shaft is fixedly installed on one side of the flipping block 22. The first locking seat 20 has a shaft hole. The rotating shaft is rotatably set in the shaft hole. An ear plate is fixedly installed on one side of the first locking seat 20. A nut is fixedly installed on the ear plate. The adjusting screw 21 is threadedly connected to the nut.

[0029] In this design, to flexibly adjust the clamping position of the wood, the adjusting screw 21 is rotated. The lower end of the adjusting screw 21 applies downward pressure to the wood, while the wood exerts a reaction force on the adjusting screw 21, causing the first clamp 20 to move upward. The clamping teeth 23 at the bottom of the first clamp 20 engage with the teeth at the bottom of the crossbeam 13, thereby achieving radial limiting of the first clamp 20. At this time, the first clamp 20 and the adjusting screw 21 can stably provide downward pressure to the wood to achieve limiting. After loosening the adjusting screw 21, the adjusting screw 21 separates from the wood, and the first clamp 20 falls under the action of gravity. The bottom surface of the flipping block 22 separates from the bottom of the crossbeam 13, and the upper end of the first clamp 20 fits against the top surface of the crossbeam 13. Pushing the first clamp 20 adjusts the downward pressure position of the adjusting screw 21 on the wood. This design has the characteristics of flexible adjustment and self-locking, making it convenient to adjust the position of the adjusting screw 21 according to the cutting position.

[0030] To facilitate the installation of the first card holder 20, the flip block 22 is rotated so that its lower end is above the first card holder 20, thus exposing the notch of the first card holder 20. The crossbeam 13 is aligned with the notch of the first card holder 20 and inserted. Then, the flip block 22 is flipped back to its original position so that the first card holder 20 and the flip block 22 form a C-shaped ring. The number of retaining rings formed by the first card holder 20 and the flip block 22 can be adjusted by adjusting the number of retaining rings on the crossbeam 13 to adjust the number of fixed positions of the wood. The addition or subtraction of the number of retaining rings is simple and easy to operate, and has better flexibility.

[0031] like Figure 5As shown, the limiting structure also includes a base plate 24 and claws 25. The base plate 24 is rotatably mounted at the lower end of the adjusting screw 21. Several claws 25 are fixedly installed on the bottom of the base plate 24. The claws 25 are symmetrical in pairs and form a group. The two claws 25 in the same group are distributed in an inward V-shape. A limiting block 14 is fixedly installed on the bottom of the slide table 12. The limiting block 14 is slidably connected to the guide rail 11. The guide rail 11 is rotatably connected to a lead screw, and the lead screw is threadedly connected to the limiting block 14.

[0032] In this solution, by rotating the adjusting screw 21, the adjusting screw 21 pushes the base plate 24 down. Multiple claws 25 on the bottom of the base plate 24 contact the wood to limit the wood. The symmetrically distributed claws 25 can suppress the rolling and slippage of the wood, which is beneficial to the precise cutting of the wood.

[0033] The working principle of this utility model is as follows: Rotating the flipping block 22 causes its lower end to rotate above the first card seat 20, thus exposing the notch of the first card seat 20. The crossbeam 13 is aligned with and inserted into the notch of the first card seat 20. Then, the flipping block 22 is flipped back to its original position, forming a C-shaped ring between the first card seat 20 and the flipping block 22. The number of retaining rings formed by the first card seat 20 and the flipping block 22 can be adjusted by changing the number of retaining rings on the crossbeam 13 to regulate the number of fixed positions of the wood. Rotating the adjusting screw 21 applies downward pressure to the wood, and the wood simultaneously exerts a reaction force on the adjusting screw 21, causing the first card seat 20 to move upward. The retaining teeth 23 at the bottom of the first card seat 20 engage with the teeth at the bottom of the crossbeam 13. The first locking seat 20 is engaged, thereby achieving radial limiting of the first locking seat 20. At this time, the first locking seat 20 and the adjusting screw 21 can stably provide downward pressure to the wood to achieve limiting. After the adjusting screw 21 is loosened, the adjusting screw 21 separates from the wood, and the first locking seat 20 falls under the action of gravity. The bottom surface of the flipping block 22 separates from the bottom of the crossbeam 13, and the upper end of the first locking seat 20 is attached to the top surface of the crossbeam 13. The first locking seat 20 can be pushed to adjust the downward pressure position of the adjusting screw 21 on the wood. The adjusting screw 21 pushes the base plate 24 down. The multiple claws 25 at the bottom of the base plate 24 contact the wood to achieve limiting of the wood. The symmetrically distributed claws 25 can inhibit the rolling and sliding of the wood, thereby achieving locking and limiting of the wood.
