Description

Technical Field

[0001] This utility model belongs to the field of production equipment technology, and in particular relates to a positioning device on a sawing machine and a sawing machine. Background Technology

[0002] In the field of metal processing, sawing is a crucial step in sample preparation. Sawing not only saves raw materials and reduces secondary processing, but also significantly improves production efficiency. Especially in sheet metal processing, double-column horizontal band saws are widely used due to their near-absence of heat-affected zones and work-hardening zones. However, in practice, existing positioning methods have some shortcomings, affecting processing accuracy and efficiency.

[0003] Traditionally, there are two main methods for positioning band saws: one is to use a light source to align the shadow line formed by the light shining on the saw blade with the pre-drawn cutting position line of the sample to be cut; the other is to use a ruler to measure the distance parallel to the shadow line to determine the size of the sample. These two methods are relatively effective when processing single or small numbers of samples, but they reveal significant problems when dealing with batches of stacked blanks or when processing samples of various sizes. First, the shadow line and the pre-drawn line may not align perfectly due to roughness, leading to inaccurate positioning. Second, to ensure cutting accuracy, it is often necessary to repeatedly confirm the sample size, which is not only time-consuming but may also result in material waste. Furthermore, these traditional positioning methods are not flexible enough for rapidly changing production demands and cannot meet the requirements of efficient production and diverse product specifications. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a device capable of positioning batches of billets.

[0005] The objective of this utility model can be achieved through the following technical solution: a positioning device for a sawing machine, comprising:

[0006] Two mounting brackets are used to fix the saw to the machine.

[0007] A connecting rod, which is mounted between the two fixed seats;

[0008] The abutment unit includes an abutment block disposed on the connecting rod, the abutment block extending at an adjustable distance relative to the connecting rod in a horizontal plane and in a direction perpendicular to the extension direction of the connecting rod.

[0009] In the positioning device for a sawing machine described above, there are two abutment blocks, and the two abutment blocks are distributed along the length direction of the connecting rod.

[0010] In the above-mentioned positioning device for a sawing machine, a connecting seat is mounted on the connecting rod, and an abutment block is disposed on the connecting seat. The abutment block can slide relative to the connecting seat, and the position of the connecting seat on the connecting rod is adjustable along the length direction of the connecting rod.

[0011] In the above-mentioned positioning device for a sawing machine, a connecting frame is fixedly provided on the connecting seat, a connecting cavity is provided on the connecting frame, the connecting rod passes through the connecting cavity, and a locking member is provided on the connecting frame to abut against the connecting rod, thereby achieving relative fixation between the connecting frame and the connecting rod, and making the position of the connecting frame on the connecting rod adjustable.

[0012] In the positioning device for a sawing machine described above, a sliding groove is provided on the connecting seat, and a connecting slider is fixedly provided at the end of the abutment block. The connecting slider extends into the sliding groove and slides in cooperation with the sliding groove.

[0013] In the positioning device for a sawing machine described above, the connecting seat is provided with a scale along the extension adjustment direction of the abutment block.

[0014] In the positioning device for a sawing machine described above, a locking element is provided on the connecting seat. The locking element is fixed to the abutment block, and the two can be separated.

[0015] In the positioning device for a sawing machine described above, an adjusting screw is screwed onto the connecting frame, one end of the adjusting screw is the operating end, and the other end of the adjusting screw is rotatably connected to the abutment block.

[0016] In the positioning device for a sawing machine described above, the operating end of the adjusting screw is fixedly provided with an operating part.

[0017] A saw includes the aforementioned positioning device for the saw.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting two fixed seats to be firmly connected to the mounting base of the band saw, the stability of the entire positioning device is ensured; the connecting rod is mounted between the two fixed seats, providing a reliable support foundation for the abutment unit. In particular, the abutment block in the abutment unit can adjust the extension distance relative to the connecting rod on the horizontal plane in a direction perpendicular to the extension direction of the connecting rod. This not only adapts to the processing needs of samples of different sizes, but also greatly reduces the need to repeatedly confirm the size of the sample to be sawed, and enhances the versatility and flexibility of the equipment.

Detailed Implementation

[0023] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0024] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0025] like Figures 1-3 As shown, a positioning device for a saw includes:

[0026] Two mounting brackets 100 are used to fix the saw to the saw.

[0027] The connecting rod 101 is mounted between two fixed seats 100;

[0028] The abutment unit includes an abutment block 200 disposed on the connecting rod 101. The abutment block 200 extends at an adjustable distance relative to the connecting rod 101 on a horizontal plane and in a direction perpendicular to the extension direction of the connecting rod 101.

[0029] In this embodiment, the positioning device for the band saw is securely connected to the mounting base of the band saw by two fixed seats 100, ensuring the stability of the entire positioning device. The connecting rod 101 is mounted between the two fixed seats 100, providing a reliable support foundation for the abutment unit. In particular, the abutment block 200 in the abutment unit can be adjusted in the horizontal plane along a direction perpendicular to the extension direction of the connecting rod 101. This not only adapts to the processing requirements of samples of different sizes, but also greatly reduces the need to repeatedly confirm the size of the sample to be sawed, and enhances the versatility and flexibility of the equipment.

[0030] When using this positioning device for sawing operations, the extension distance of the abutment block 200 is first adjusted to ensure precise alignment and contact with the side of the sample to be sawed. The abutment block 200 plays a crucial role in pre-positioning, ensuring the consistency and accuracy of each cut. Once the abutment block 200 is in contact with and fixed to the sample block, the clamping mechanism on the band saw can be used for secondary clamping and reinforcement of the sample. This device adapts to the processing needs of various sample specifications and types, increasing the application range and flexibility of the equipment.

[0031] It is worth mentioning that the fixed base and the mounting base of the saw are detachably connected.

[0032] More preferably, there are two abutment blocks 200, and the two abutment blocks 200 are distributed along the length direction of the connecting rod 101.

[0033] In this embodiment, when the number of abutment blocks 200 is set to two and distributed along the length direction of the connecting rod 101, the positioning device can achieve a more stable and reliable bidirectional limiting function during use. The two abutment blocks 200 act on the two ends or sides of the sample respectively, which can not only accurately limit the starting position of the sample in the sawing direction, but also effectively prevent the sample from shifting or rotating during clamping and sawing, thereby further improving the cutting accuracy and operational safety.

[0034] It is worth mentioning that the abutting end of the abutting block 200 is a plane. The plane structure of the abutting end can achieve a larger area of ​​stable contact with the sample surface, avoiding the positioning instability or slippage that may be caused by point contact or line contact, thereby further improving the reliability of positioning and the accuracy of sawing.

[0035] Preferably, a connecting seat 201 is mounted on the connecting rod 101, and an abutment block 200 is disposed on the connecting seat 201. The abutment block 200 can slide relative to the connecting seat 201. The position of the connecting seat 201 on the connecting rod 101 is adjustable along the length direction of the connecting rod 101.

[0036] In this embodiment, by setting the abutment block 200 on the connecting seat 201 and allowing the abutment block 200 to slide and adjust relative to the connecting seat 201, precise positioning of samples of different widths or lengths can be easily achieved without moving the entire positioning device. The position of the connecting seat 201 is adjustable along the length of the connecting rod 101, which means that the user can flexibly adjust the distance between the two abutment blocks 200 according to actual needs to adapt to different sample sizes.

[0037] More preferably, a connecting frame 202 is fixedly provided on the connecting seat 201, and a connecting cavity 203 is provided on the connecting frame 202. The connecting rod 101 passes through the connecting cavity 203, and a locking member 204 is provided on the connecting frame 202 to abut against the connecting rod 101, so as to achieve relative fixation between the connecting frame 202 and the connecting rod 101, and make the position of the connecting frame 202 on the connecting rod 101 adjustable.

[0038] In this embodiment, the connecting frame 202 can slide freely on the connecting rod 101, allowing the user to quickly adjust the distance between the two abutment blocks 200 according to the size of the sample, thereby adapting to the processing needs of samples of different specifications without reconfiguration or equipment replacement; the tight abutment between the locking member 204 and the connecting rod 101 ensures that once adjusted and locked, the connecting frame 202 will not move unexpectedly during the sawing process, thus ensuring the safety of operation and cutting accuracy.

[0039] As an alternative, the locking component 204 includes a locking handle, which is screwed to the connecting frame 202. The locking handle passes through the connecting frame 202 and abuts against the connecting rod 101 to fix the relative position of the connecting frame 202 and the connecting rod 101.

[0040] More preferably, the connecting seat 201 is provided with a sliding groove, and the end of the abutment block 200 is fixedly provided with a connecting slider 210, which extends into the sliding groove and slides with the sliding groove.

[0041] In this embodiment, the design of the groove and connecting slider 210 allows the abutment block 200 to move precisely and smoothly in a specific direction (typically perpendicular to the connecting rod 101). This structure ensures high accuracy when adjusting the sample size and facilitates more precise positioning. The sliding fit between the connecting slider 210 and the groove provides additional support points, increasing the stability of the abutment block 200 during operation. This effectively prevents displacement due to vibration or external forces during sawing, ensuring the accuracy and consistency of the cut.

[0042] It is worth mentioning that the connecting slider 210 is T-shaped. When used in conjunction with the corresponding groove, the connecting slider 210 provides stronger stability and anti-displacement capability. The T-shaped design increases the contact area between the slider and the groove, effectively preventing the slider from tilting or coming off during operation, and ensuring the stability of the abutment block 200 during adjustment and operation.

[0043] Preferably, the connecting seat 201 is provided with a scale 205 along the extension adjustment direction of the abutment block 200. Specifically, the scale 205 is marked on the side of the connecting seat 201. The scale 205 allows the operator to intuitively read the extension distance of the abutment block 200, thereby achieving precise control of the sample size. This is more scientific and reliable, significantly improving the consistency and accuracy of the sawing position.

[0044] In a further preferred embodiment, the connecting seat 201 is provided with a guide ring 206, the abutment ring extends through the guide ring 206, and the guide ring 206 is provided with a locking member 207, which is fixed to the abutment block 200 and the two can be separated.

[0045] In this embodiment, when adjustments are needed based on different sample sizes, the abutment block 200 can be easily moved to the desired position by unlocking the locking member 207, and then relocked to fix the position of the abutment block 200. The presence of the locking member 207 ensures the stability of the abutment block 200 during the sawing process, preventing it from shifting or loosening due to external forces, thereby ensuring cutting accuracy and operational safety.

[0046] Specifically, the locking component 207 is a locking handle, which is screwed to the guide ring 206. The locking handle passes through the guide ring 206 and abuts against the abutment block 200 to lock the abutment block 200, while also making the two separable.

[0047] like Figure 3 As shown, preferably, an adjusting screw 208 is screwed onto the connecting frame 202. One end of the adjusting screw 208 is the operating end, and the other end of the adjusting screw 208 is rotatably connected to the abutment block 200.

[0048] In a further preferred embodiment, the operating end of the adjusting screw 208 is fixedly provided with an operating part 209.

[0049] In this embodiment, fine-tuning using the adjusting screw 208 allows for very precise position adjustments, ensuring the height accuracy of the sample positioning. Operating the adjusting screw 208 via the control unit 209 (such as a handwheel or knob) makes even very minor adjustments simple and easy. Operators can achieve accurate positioning without applying excessive force, improving work efficiency.
