Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a rail longitudinal cutting fixture. Background Technology

[0002] Because of its good strength, the rail can be used as the blank material for the parking device support beam. That is, the rail head is cut off, and the remaining part becomes the T-shaped parking device support beam. However, the rail head is narrow and the rail base is wide, and the rail lies on the saw table at an angle, making it impossible to process. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a rail longitudinal cutting clamp that is easy to process.

[0004] To achieve the above objectives, the technical solution adopted by this utility model rail longitudinal cutting clamp is as follows:

[0005] A rail longitudinal cutting fixture includes a strip-shaped positioning block located on one side of the saw blade clearance groove. The strip-shaped positioning block is fixed to the saw table by bolts and fastening nuts. The back surface of the strip-shaped positioning block is parallel to the saw blade clearance groove. Several first pads are provided between the strip-shaped positioning block and the saw blade clearance groove to support the rail web in a horizontal state. A clamping mechanism is provided on the same side of the first pads to press the rail against the top surface of the first pads.

[0006] Preferably, the clamping mechanism includes a pressure plate sleeved on the outside of the bolt, a pressure head is provided between the bottom of one side of the pressure plate and the rail web, a second pad is provided between the bottom of the other side of the pressure plate and the saw table, and a locking nut that is threadedly connected to the bolt is provided above the pressure plate.

[0007] Preferably, the clamping mechanism includes a base fixed to the saw table, a mounting plate hinged to the bottom outer side of the base, a cylinder fixed to the mounting plate, an adapter fixed to the telescopic rod of the cylinder, a pressure arm hinged to the adapter, the side of the pressure arm adjacent to the cylinder being hinged to the base via an H-shaped bracket, and a pressure block for clamping the rail web provided on the side of the pressure arm away from the cylinder.

[0008] Preferably, it also includes a third pad for supporting the rail head.

[0009] Compared with the prior art, this utility model has the following advantages:

[0010] The first pad supports the rail web, making the rail web horizontal. The strip positioning block quickly positions the cutting position of the rail, and then the rail is fixed by the clamping mechanism in cooperation with the first pad, thus facilitating the cutting of the rail head by the saw.

Detailed Implementation

[0016] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.

[0017] Example 1, as Figure 1-4 As shown, a rail longitudinal cutting fixture includes a third pad 2 located to the left of the saw blade clearance groove 1 and a strip-shaped positioning block 3 located to the right of the saw blade clearance groove. The third pad is used to support the rail head and prevent it from falling and damaging the sawing machine table after cutting. The front and rear sides of the strip-shaped positioning block are fixed to the sawing machine table by bolts 4 and fastening nuts 5, respectively. The back surface of the strip-shaped positioning block is parallel to the saw blade clearance groove. Two first pads 6 are placed between the strip-shaped positioning block and the saw blade clearance groove to support the rail web in a horizontal state. The position of the first pads is... Corresponding to the bolt position, a clamping mechanism is installed on the same side of the first pad. The clamping mechanism presses the rail against the top surface of the first pad. The clamping mechanism includes a pressure plate 71 sleeved on the outside of the bolt. A pressure head 72 is placed between the bottom left side of the pressure plate and the rail web. A second pad 73 is placed between the bottom right side of the pressure plate and the saw table. The pressure plate, pressure head, and second pad can also be connected as a whole. However, the weight of the whole after connection is large and it is inconvenient to pick up and put down. Therefore, it is better to separate them. A locking nut 74 that is threadedly connected to the bolt is arranged above the pressure plate.

[0018] The specific working process and principle of Example 1: The bottom of the rail is placed against the back surface of the strip positioning block. The first pad supports the rail web, and the third pad supports the rail head. A pressure head is placed above the rail web, with the pressure head corresponding to the position of the first pad. During placement, the pressure plate can be inserted from the top of the bolt guided by the bolt. The left bottom surface of the pressure plate rests on the top surface of the pressure head, and the right bottom surface of the pressure plate rests on the top surface of the second pad. Tightening the lock nut presses the rail firmly against the top surface of the first pad, thus facilitating the cutting of the rail head by the saw.

[0019] Example 2, as Figure 1-4 As shown, a rail longitudinal cutting fixture includes a third pad 2 located on the left side of the saw blade clearance groove 1 and a strip-shaped positioning block 3 located on the right side of the saw blade clearance groove. The third pad is used to support the rail head and prevent it from falling and damaging the sawing machine table after cutting. The front and rear sides of the strip-shaped positioning block are fixed to the sawing machine table by bolts 4 and fastening nuts 5, respectively. The back surface of the strip-shaped positioning block is parallel to the saw blade clearance groove. Two first pads are placed between the strip-shaped positioning block and the saw blade clearance groove to support the rail web in a horizontal state. 6. The position of the first pad corresponds to the position of the bolt. A clamping mechanism is installed on the same side of the first pad. The clamping mechanism presses the rail against the top surface of the first pad. The clamping mechanism includes a base 81 fixed to the saw table. A mounting plate 82 is hinged to the bottom of the outer side of the base. A cylinder 83 is fixed to the mounting plate. An adapter 84 is fixed to the telescopic rod of the cylinder. A pressure arm 85 is hinged to the adapter. The side of the pressure arm adjacent to the cylinder is hinged to the base through an H-shaped bracket 86. A pressure block 87 for clamping the rail web is fixed to the side of the pressure arm away from the cylinder.

[0020] The specific working process and principle of Example 2: The bottom of the rail is placed against the back surface of the strip positioning block, the first pad supports the rail web, the third pad supports the rail head, the cylinder is started, the cylinder extension rod extends, the pressure arm rotates, and the pressure head presses the rail firmly against the top surface of the first pad, thereby facilitating the sawing machine to cut off the rail head.
