Description

Technical Field

[0001] The utility model relates to the field of metal cutting and fixing, in particular to a locking clamp. Background Art

[0002] Cutting is a processing method that uses cutting tools to cut off the excess material layer on the blank or workpiece to obtain the specified geometric shape, size and surface quality of the workpiece. Among them, the cutting plane refers to the plane that passes through a selected point of the cutting edge of the tool and is tangent to the workpiece processing surface.

[0003] A milling machine mainly refers to a machine tool that uses a milling cutter to process various surfaces of a workpiece. Usually, the rotation of the milling cutter is the main motion, and the movement of the workpiece and the milling cutter is the feed motion. It can process planes, grooves, various curved surfaces, gears, etc.

[0004] In the process of plane cutting, a clamp is usually used to fix the workpiece, but the existing clamp only clamps the workpiece by two clamping blocks. When the workpiece is tubular or has a smooth surface, it is easy to slip and loosen during the cutting process, which is dangerous and easily causes damage to the workpiece. Utility Model Content

DETAILED DESCRIPTION

[0031] The present invention provides a locking fixture for fixing and locking the gear rod, thereby improving the accuracy and convenience of gear rod cutting.

[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0033] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product, or server that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or modules that are not clearly listed or inherent to these processes, methods, products, or devices.

[0034] Reference Figure 1 A locking clamp of this embodiment includes a platform 1 and a fastener 2 disposed on the platform 1. The fastener 2 includes a plurality of positioning blocks 21 that fix the gear rod in pairs, a connecting rod 22 that passes through the plurality of positioning blocks 21, and a first fixing member 23 and a second fixing member 24 disposed at both ends of the connecting rod 22. The first fixing member 23 and the second fixing member 24 move toward the positioning blocks 21 to force the gear rod to be fixed between the two positioning blocks 21.

[0035] In the embodiment of the present application, three positioning blocks 21 are provided, and the gear rod is provided between two adjacent positioning blocks 21. The positioning blocks 21 are close to each other and abut against the gear rod to form a fixation; then the three positioning blocks 21 are passed through the connecting rod 22, and the first fixing member 23 and the second fixing member 24 are brought close to each other to force each positioning block 21 to abut against the gear rod, and further fix and lock the gear rod. This solution is simple to operate, and the gear rod is firmly fixed, which is convenient for workers to perform heavy cutting.

[0036] Specifically, the corresponding positioning blocks 21 are provided with fixing grooves 25 for fixing the gear rod on the abutting surfaces facing the gear rod, and the groove surfaces of the fixing grooves 25 are in close contact with the peripheral side surfaces of the gear rod, thereby facilitating the pre-positioning of the gear rod and accelerating the locking and fixing of the gear rod.

[0037] At the same time, a limiting groove 26 is formed between two adjacent positioning blocks 21, and the limiting groove 26 communicates with the fixing groove 25. Since the types of the gear rods may be slightly different, the width of the limiting groove 26 can be limited according to the diameter of the gear rod, so as to facilitate locking of gear rods of different types.

[0038] Furthermore, the limiting groove 26 extends in the direction of the platform 1 to form a clearance groove 27, which is in communication with the limiting groove 26. In addition, the chamber of the clearance groove 27 is larger than the chamber of the limiting groove 26. In this embodiment, the opening of the clearance groove 27 can not only improve the toughness of the three positioning blocks 21, but also reduce the risk of bending or breaking of the positioning blocks 21 during heavy cutting; at the same time, the clearance groove 27 has the function of liquid diversion, and cutting fluid will be added during heavy cutting (cutting fluid helps lubrication, cooling, cleaning, rust prevention, etc. during cutting), and the clearance groove 27 helps to discharge liquids such as cutting fluid, thereby improving the cutting effect of the gear rod.

[0039] Combination Figure 2 The positioning block 21 is integrally extended with the length direction of the gear rod and has a positioning piece 3 for positioning and abutting one end of the gear rod. Furthermore, the positioning piece 3 includes a connecting block 31 connected to the positioning block 21 and a positioning block 32 abutting the gear rod, and the positioning block 32 is integrally arranged on both sides of the connecting block 31. The positioning piece 3 can pre-position the gear rod in another direction; since the position of the positioning piece 3 is fixed, the cutting part is in the same place during heavy cutting, which improves the cutting accuracy and facilitates the operation of the workers.

[0040] Reference Figure 3 , one end of the connecting rod 22 is integrally provided with the first fixing member 23, and the other end of the connecting rod 22 is provided with a thread and is threadedly connected with the second fixing member 24. Among them, in the application embodiment, the first fixing member 23 is integrally formed with the connecting rod 22 as a screw rod, and the second fixing member is a nut that is rotatably matched and tightened with the screw rod. The second fixing member 24 is matched with the connecting rod 22 through a threaded connection, so that the first fixing member 23 and the second fixing member 24 move toward the positioning block 21 so that the gear rod can be fixed, which not only facilitates the locking of the gear rod but also improves the stability of the gear rod locking.

[0041] Specifically, a buffer ring is provided on one side of the first fixing member close to the positioning block and on one side of the second fixing member close to the positioning block. The buffer ring can be a metal or rubber gasket. The function of the buffer ring is to reduce the wear of the first fixing member and the second fixing member on the positioning block when the first fixing member and the second fixing member are close to the positioning block and tightly abut the positioning block.
