During the processing of titanium rods, different processing procedures will be adopted according to the number of processing.

In large-scale production, special fixtures are usually set up to open holes to accommodate the workpieces and fasteners are used to clamp and fix the titanium rods.

[0003] However, in the existing titanium rod clamps, the installation and removal process of the fasteners that abut the titanium rod is relatively difficult. Flat head screws are usually used for clamping and fixing. The contact area between the flat head screws and the titanium rod is small, which can easily exert a large pressure on the surface of the titanium rod and damage the surface of the titanium rod.

[0029] Titanium rods are common workpieces in the industrial field and have a wide range of usage scenarios. During the processing of titanium rods, different processing procedures will be adopted according to the number of processing. For example, in small-batch production, manual clamping and subsequent processing are performed through marking, drilling, adjusting positioning, etc. The positioning accuracy is low and the operation is time-consuming. In large-scale production, special fixtures are usually set up to open holes to accommodate the workpieces and fasteners are used to clamp and fix the titanium rods.

[0030] However, in the existing titanium rod clamps, the installation and removal process of the fasteners that abut the titanium rod is relatively difficult. Flat head screws are usually used for clamping and fixing. The contact area between the flat head screws and the titanium rod is small, which can easily exert a large pressure on the surface of the titanium rod and damage the surface of the titanium rod. Alternatively, a flat base is additionally machined on the titanium rod for clamping, which is a cumbersome process and increases production costs.

[0031] Compared with the prior art, the titanium rod clamp provided in the embodiment of the present application has the following beneficial effects:

[0032] The clamping plate is provided with pressure by the fastener, and the titanium rod is clamped by the V-shaped clamping surface and the locking hole of the clamping plate, thereby avoiding damage to the surface of the titanium rod and improving the working stability of the titanium rod clamp.

[0033] The following will be combined Figures 1 to 5, the titanium rod clamp and titanium rod processing system provided in the embodiments of the present application are described in detail through specific examples.

[0034] Please also read Figures 1 to 5 , Figure 1 A schematic diagram of a partial structure of a titanium rod processing system and a titanium rod provided in an embodiment of the present application; Figure 2 A schematic diagram of the explosion structure of the titanium rod fixture and the titanium rod provided in the embodiment of the present application; Figure 3 A schematic diagram of the structure of a titanium rod clamp provided in an embodiment of the present application; Figure 4 for Figure 3 A schematic structural diagram of the titanium rod fixture from another angle shown; Figure 5 for Figure 3 The cross-sectional structure diagram of the titanium rod clamp is shown. One embodiment of the present invention provides a titanium rod clamp 100 for processing a titanium rod 500 , comprising a fixing seat 10 , a clamping plate 30 and a fastener 50 . The fixing seat 10 is provided with a locking hole 11 along the first direction. The locking hole 11 is arranged in the middle of the fixing seat 10, and its shape and size correspond to the titanium rod 500. The outer peripheral surface of the fixing seat 10 is provided with abutment holes 13 and positioning grooves 15 in sequence along the second direction toward the locking hole 11. The second direction is perpendicular to the first direction. The abutment holes 13, the positioning grooves 15 and the locking hole 11 are connected in sequence; the clamping plate 30 is arranged in the positioning groove 15, and the clamping plate 30 is concavely provided with a clamping surface 31 on the side close to the locking hole 11, and the cross-sectional profile of the clamping surface 31 along the first direction is V-shaped; the fastener 50 is passed through the abutment hole 13 and movably abuts against the wall of the clamping plate 30 on the side away from the end face, so as to push the clamping plate 30 and make the clamping surface 31 abut against the titanium rod 500.

[0035] It can be understood that the locking hole 11 is used to accommodate the titanium rod 500 to be processed. Specifically, the cross-sectional shape and size of the locking hole 11 along the first direction are set corresponding to the titanium rod 500. In this way, during the operation of the titanium rod clamp 100, the titanium rod 500 to be processed can be inserted into the locking hole 11 along the first direction, so that the titanium rod 500 has a relatively fixed positional relationship with the fixing seat 10 of the titanium rod clamp 100. The fixing seat 10 is also formed with a positioning groove 15 for accommodating the clamping plate 30 and a corresponding abutment hole 13 extending from the outer peripheral surface of the fixing seat 10 along the second direction toward the positioning groove 15. The abutment hole 13 is used to flexibly connect the fastener 50 and guide the moving direction of the fastener 50 during the active connection process. Specifically, the abutment hole 13, the positioning groove 15 and the locking hole 11 are connected, so that at least a portion of the end surface of the clamping plate 30 arranged in the positioning groove 15 is exposed at the connection between the positioning groove 15 and the locking hole 11, that is, the clamping surface 31 recessed on the side of the clamping plate 30 close to the locking hole 11 is at least partially exposed there. During the operation of the titanium rod clamp 100, the clamping surface 31 is used to abut against the outer circumferential surface of the columnar workpiece to be processed. The fastener 50 in the abutment hole 13 is at least partially able to movably abut the clamping surface 31 of the clamping plate 30. The profile of the cross section of the clamping surface 31 along the first direction is V-shaped. In this way, the relatively inclined end surfaces on both sides provide relative support force for the fastener 50 and together with the end surface of the locking hole 11, enclose and limit the position of the titanium rod 500, thereby realizing the clamping process of the titanium rod 500 to be processed, so that the fastener 50, the clamping plate 30 and the titanium rod 500 have a relatively stable positional relationship. While ensuring the supporting effect of the titanium rod 500 by the titanium rod clamp 100, the clamping plate 30 further increases the contact area with the titanium rod 500, thereby reducing the pressure on the titanium rod 500 per unit area, avoiding the damage of the end surface of the titanium rod 500 caused by excessive local pressure, and further improving the clamping effect and working stability of the titanium rod clamp 100.

[0036] As a possible implementation, please also refer to Figures 1 to 4 The fixing seat 10 is also formed with a first positioning hole 17, which is extended along the second direction and is arranged at intervals with the abutment hole 13. The titanium rod clamp 100 also includes a first positioning column 70, which is passed through the first positioning hole 17 and fixedly connected to the clamping plate 30.

[0037] It is understandable that the first positioning column 70 passing through the first positioning hole 17 further stabilizes the relative position relationship between the clamping plate 30 and the fixing seat 10. The connection method between the first positioning column 70 and the first positioning hole 17 can be a pin connection, a clamping connection, an elastic connection or a threaded connection, etc., which is not specifically limited in this application. The clamping plate 30 disposed in the positioning groove 15 has a tendency to move along the first direction and / or the second direction. Its activity tendency along the second direction is limited by the fasteners 50 on both sides of the positioning groove 15 or the side wall surface of the positioning groove 15, while the movement tendency along the first direction is limited by the first positioning column 70 fixedly connected to the clamping plate 30 in the first positioning hole 17. Specifically, when the clamping plate 30 has a tendency to move along the first direction, the static pressure generated is transmitted to the first positioning column 70 to which it is fixed, and is offset by the pressure applied by the inner wall of the first positioning hole 17 toward the first positioning column 70. In this way, the relative position relationship between the clamping plate 30 and the positioning groove 15 is further improved, so that the clamping plate 30 has a relatively stable position relationship, that is, the use stability of the titanium rod clamp 100 is further improved.

[0038] As a possible implementation, see Figures 1 to 4 The number of positioning holes is at least two, at least two first positioning holes 17 are symmetrically arranged on both sides of the abutment hole 13 along the axis of the extension direction of the abutment hole 13, and the titanium rod clamp 100 includes at least two first positioning columns 70, and at least two first positioning columns 70 are respectively passed through a first positioning hole 17 and fixedly connected to the clamping plate 30.

[0039] It can be understood that at least two first positioning holes 17 are symmetrically arranged on both sides of the abutment hole 13. In this way, at least two first positioning columns 70 are respectively fixedly connected to the clamping plate 30 at the positions on both sides of the abutment hole 13, thereby limiting the possible movement tendency of the clamping plate 30 along the first direction. The component force that is not parallel to the extension direction will be equal in size and opposite in direction on both sides along the axis of the extension direction of the abutment hole 13 and offset each other, further ensuring the stable position relationship of the clamping plate 30 in the positioning groove 15, that is, further improving the working stability and clamping accuracy of the titanium rod clamp 100.

[0040] As a possible implementation, see Figure 2 , Figure 3 and Figure 5 At least two avoidance holes 14 are recessed on the inner wall surface of the positioning groove 15 near the positioning hole. The avoidance holes 14 are opened toward the clamping plate 30 . The at least two avoidance holes 14 are arranged at intervals along the extending direction of the first positioning hole 17 .

[0041] It can be understood that the avoidance hole 14 recessed in the inner wall of the positioning groove 15 can provide a certain space margin for the movement or adjustment process of the clamping plate 30 in the positioning groove 15. During the operation of the titanium rod clamp 100, it can ensure that the size of the clamping plate 30 is not much different from that of the positioning groove 15. While having better space utilization, it can also avoid the collision or damage that may be caused by the clamping plate 30 with the inner wall of the positioning groove 15 during the process of being installed in the positioning groove 15 or being removed from the positioning groove 15, thereby further improving the working stability and service life of the clamping plate 30 and the titanium rod clamp 100.

[0042] It should be noted that at least two avoidance holes 14 arranged at intervals along the extension direction of the positioning hole also provide a certain space margin for the process of installing the first mounting column in the first mounting hole 310. When the installation angle of the first mounting column may deviate from the preset angle or length, fine-tuning can be performed through the avoidance hole 14, thereby ensuring the stable restriction effect on the clamping plate 30 when the first mounting column is fixedly connected to the clamping plate 30, further ensuring the working stability and clamping accuracy of the titanium rod clamp 100.

[0043] As a possible implementation, see Figure 3 and Figure 5 The number of the avoidance holes 14 is at least four, and the at least four avoidance holes 14 are symmetrically arranged along the extending direction of the abutment hole 13 .

[0044] It can be understood that the number of avoidance holes 14 is at least four, and at least four avoidance holes 14 are symmetrically arranged along the extension direction of the abutment hole 13. In this way, each side of the two sides of the extension direction of the abutment hole 13 is ensured to have at least two avoidance holes 14. In this way, when the number of first positioning holes 17 is at least two, it can be ensured that at least two first positioning holes 17 are connected to at least two avoidance holes 14, further ensuring the installation stability of each first mounting column, so that each first mounting column has sufficient installation space and avoidance margin, further improving the working accuracy and working stability of the first mounting column, the clamping plate 30 and the titanium rod clamp 100.

[0045] As a possible implementation, see Figures 1 to 3 The fixing seat 10 also includes a second positioning hole 19, which is arranged on the side of the locking hole 11 away from the abutment hole 13, and extends in a direction away from the second direction to connect with the locking hole 11. The titanium rod clamp 100 also includes a second positioning column 90, which is passed through the second positioning hole 19 for movable abutment with the titanium rod 500.

[0046] It can be understood that the second positioning column 90 arranged in the second positioning hole 19 is arranged on the side of the locking hole 11 away from the abutment hole 13, and combined with the first positioning column 70 arranged in the first positioning hole 17 on the same side of the abutment hole 13, it further increases the clamping plate 30 in the positioning groove 15 to have a relatively stable positional relationship with the fixed seat 10, thereby ensuring that the titanium rod 500 to be processed clamped and fixed by the clamping plate 30 has a relatively fixed positional relationship with it, that is, the clamping accuracy and clamping stability of the titanium rod clamp 100 are further improved.

[0047] As a feasible implementation manner, the abutment hole 13 is a threaded hole, and the fastener 50 is threadedly connected to the abutment hole 13 .

[0048] It can be understood that, compared with sliding connection, hinged connection, elastic connection or snap-on connection, the fastener 50 movably connected to the fixing seat 10 by a threaded connection has relatively stable rigidity and stability with the fixing seat 10, can withstand greater pressure and torque after tightening, can be tightened or disassembled by bolts or nuts of different types, is simple and convenient to operate, has a linear motion process, and can achieve subtle position adjustment or stress adjustment by adjusting the position of the bolt or nut, further improving the working accuracy and clamping stability of the fastener 50 and the titanium rod clamp 100.

[0049] As a possible implementation, see Figure 5 , the width of the positioning groove 15 along the second direction is defined as D1, the maximum width of the clamping plate 30 along the second direction is defined as D2, and D2<D1.

[0050] It can be understood that during the operation of the titanium rod clamp 100, the fastener 50 arranged in the abutment hole 13 is limited by the extension direction of the abutment hole 13, and the pressure applied by the fastener 50 to the clamping plate 30 also extends along the second direction. At this time, the width D1 of the positioning groove 15 along the second direction is set to be greater than the width D2 of the clamping plate 30 along the second direction. In this way, the clamping plate 30 can have space to move along the second direction in the positioning groove 15. In the process of extending the titanium rod 500 to be processed into the locking hole 11 before being fixed, it will not be hindered by the clamping plate 30, which further facilitates the installation and disassembly process of the titanium rod 500 to be processed, that is, further improves the use efficiency of the titanium rod clamp 100.

[0051] See also Figures 1 to 5The technical solution of the utility model also proposes a titanium rod processing system 1000, which includes a base 300 and any one of the above-mentioned titanium rod clamps 100. The specific structure of the titanium rod clamp 100 refers to the above-mentioned embodiment. Since the titanium rod clamp 100 of this solution adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0052] In another feasible implementation manner of the present application, the base 300 is formed with a mounting hole 310 , and a tail handle 16 is protruded from a side of the fixing seat 10 away from the locking hole 11 , and the tail handle 16 is detachably connected to the mounting hole 310 .

[0053] In another feasible embodiment of the present application, a snap-in groove 18 is formed on the side of the tail handle 16 facing away from the abutment hole 13, and a snap-in protrusion 330 is protruded from the base 300 corresponding to the snap-in groove 18. When the tail handle 16 is detachably connected to the mounting hole 310, the snap-in protrusion 330 is at least partially snap-connected to the snap-in groove 18.

[0054] It can be understood that the tail handle 16 detachably connected to the mounting hole 310 may have a tendency to rotate along the center of the circular cross-section during operation when the mounting hole 310 and the cross-section of the tail handle 16 are circular. A clamping groove 18 is formed at the end of the tail handle 16 away from the abutment hole 13, and a corresponding clamping protrusion 330 is convexly provided on the clamp body. In this way, the mounting hole 310 and the clamping protrusion 330 together construct a plurality of fixed support points of the titanium rod processing system 1000, thereby avoiding the possible rotation tendency of the titanium rod processing system 1000 and further improving the use accuracy and stability of the titanium rod processing system 1000.

[0055] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
