Description

Technical Field

[0001] The present application relates to the technical field of tooth palm welding, and in particular to a tool for welding the palm and back of a tooth. Background Art

[0002] The tooth palm, also known as the cone palm, is one of the main parts of a rotary drill bit. A rotary drill bit is assembled and welded by three tooth palms. The tooth palm plays the role of supporting and connecting the drill bit body and the cone.

[0003] When welding the tooth palm, a welding robot is usually used. Before welding, the workpiece needs to be fixed on the tooling. The tooling can accurately position the workpiece to ensure that the welding robot's welding gun can accurately reach the welding position, which helps to improve welding accuracy and welding quality, and ensure the stability and accuracy of the workpiece during the welding process.

[0004] Welding tooling generally includes a turntable and a fixed seat located on the turntable. The fixed seat is used to place and fix the workpiece. The turntable can adjust the position of the fixed seat by rotating it, so as to facilitate welding of the tooth palm from different directions. The tooth palm has two inclined bottom surfaces, and an angle is formed between the two bottom surfaces. The fixed seat is provided with a placement groove that fits the bottom surface of the tooth palm. Different tooth palms form different angles. There are many types of tooth palms, and the turntable and the fixed seat are mostly non-detachable. The fixed seat cannot fix the tooth palms with different angles.

[0005] Therefore, a new tool for welding the palm and back of the tooth is urgently needed to solve the problem that the fixing seat cannot fix the tooth palms with different angles, thereby improving the application range of the welding tool. Utility Model Content

[0006] In order to fix tooth palms with different angles, the present application provides a tool for welding the palm and back of the tooth palm.

[0007] The present application provides a tool for welding the palm and back of a tooth, which adopts the following technical solution:

[0008] A tool for welding the palm and back of a tooth, comprising a turntable, a fixing seat for fixing the tooth palm being provided on the turntable, a placement groove adapted to the tooth palm being formed in a depression on the fixing seat, a plurality of fixing seats being provided, and a placement surface of the placement groove on each fixing seat forming an angle different from that provided by the angle, a base being further provided on the turntable and the fixing seat being mounted on the base, a limiting member being detachably connected to the base, and the limiting member being inserted into one of the fixing seats to lock the fixing seat and the base.

[0009] By adopting the above technical solution, compared with the existing technology, there are multiple fixing seats. In order to adapt to tooth palms with different angles, the fixing seats can be replaced so that the bottoms of tooth palms with different angles are all in contact with the placement surface of the fixing seat, thereby enabling the fixing seat to fix tooth palms with different angles.

[0010] Optionally, a first through hole is provided on the fixing seat, a second through hole is provided on the base, and the limiting member is interference fit with the first through hole and the second through hole.

[0011] By adopting the above technical solution, the limiting member is interference fit with the first through hole and the second through hole, so that the base and the fixing seat are locked and fixed, ensuring the stability of the tooth palm position on the fixing seat, thereby ensuring the accuracy of welding and improving the welding quality.

The limiting member includes a magnetic strip 1, and the magnetic strip 1 is magnetically attracted to the fixing seat and the base.

[0013] By adopting the above technical solution, the magnetic strip 1 passes through the first through hole and the second through hole into the fixed seat and the base. The magnetic strip 1 is magnetically attracted to the fixed seat and the base, thereby fixing the fixed seat and the base, ensuring that the tooth palm is firmly fixed on the tooling and avoiding displacement of the tooth palm position.

[0014] Optionally, one end of the limiting member protrudes to form a limiting protrusion, and the limiting protrusion conflicts with the side wall of the base.

[0015] By adopting the above technical solution, a limiting protrusion is provided at one end of the limiting member, which conflicts with the side wall of the base, thereby limiting the position of the limiting member in the fixing seat and the base. The limiting protrusion can be used to facilitate the removal of the limiting member from the fixing seat and the base, thereby facilitating the replacement of the fixing seat.

[0016] Optionally, a positioning piece is protruding from the fixing seat, and a positioning groove is recessed on the base to cooperate with the positioning piece.

[0017] By adopting the above technical solution, the positioning piece is inserted into the positioning groove to realize the positioning cooperation between the fixing seat and the base, which is convenient for fixing the fixing seat and the base, ensuring the accuracy of the position of the fixing seat on the base, and further ensuring the accuracy of the tooth palm welding position.

[0018] Optionally, a locking hole is provided on the fixing seat, and a locking piece is provided in the inner thread of the locking hole. A locking pressure rod is provided between the locking piece and the fixing seat. The locking piece passes through the locking pressure rod and is locked with the fixing seat, and one side of the locking pressure rod is in contact with the tooth palm.

[0019] By adopting the above technical solution, the locking piece cooperates with the locking hole thread to realize the locking fixation of the locking pressure rod and the fixing seat. One side of the locking pressure rod contacts the tooth palm, and then the tooth palm is firmly installed on the fixing seat to avoid the tooth palm from being offset and affecting the welding accuracy.

[0020] Optionally, a first keyway is recessed on the base, and a second keyway is recessed on the turntable. Positioning keys are provided in the first and second keyways, and the positioning keys are interference fit with the first and second keyways to lock the base and the turntable.

[0021] By adopting the above technical solution, the positioning key is connected to the first keyway and the second keyway through the key, thereby limiting the movement of the base and the turntable in the horizontal direction, ensuring the accuracy of the tooth palm welding position.

[0022] Optionally, a second magnetic strip is embedded on the turntable, and a groove for the second magnetic strip to penetrate is formed on the fixing seat, and the second magnetic strip is magnetically attracted to the fixing seat.

[0023] By adopting the above technical solution, the second magnetic strip on the turntable is inserted into the groove on the fixing seat, and the magnetic strip and the fixing seat are magnetically fixed, thereby achieving the fixation of the turntable and the base.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. Compared with the existing technology, the number of fixing bases is multiple. To adapt to the tooth palms with different angles, the fixing bases can be replaced, so that the bottoms of the tooth palms with different angles are all in contact with the placement surface of the fixing base, thereby enabling the fixing base to fix the tooth palms with different angles;

[0026] 2. The magnetic strip 1 passes through the first through hole and the second through hole and penetrates into the fixing seat and the base. The magnetic strip 1 is magnetically attracted to the fixing seat and the base, thereby fixing the fixing seat and the base, ensuring that the tooth palm is firmly fixed on the tooling and preventing the tooth palm from shifting.

[0027] 3. The locking piece cooperates with the locking hole thread to realize the locking fixation of the locking pressure rod and the fixing seat. One side of the locking pressure rod contacts the tooth palm, thereby firmly installing the tooth palm on the fixing seat to prevent the tooth palm from deflecting and affecting the welding accuracy.

In this embodiment, the fixed seat 1, the base 2 and the turntable 3 are all made of stainless steel to ensure that the tooling has the characteristics of high strength, and thus can stably fix and press the workpiece. The tooth palm has two inclined bottom surfaces, and the fixed seat 1 has two inclined placement surfaces 4. A placement groove 5 for placing the tooth palm is formed between the two placement surfaces 4. The tooth palm is installed in the placement groove 5 of the fixed seat 1, and the bottom of the tooth palm fits with the placement surface 4 of the placement groove 5 to achieve stable fixation of the tooth palm. There are many types of tooth palms, and the angles on different tooth palms are different. The number of fixed seats 1 is set to multiple, and the placement surface 4 of the fixed seat 1 is adapted to tooth palms with different angles.

A locking piece 8 is provided in the locking hole 9. The locking piece 8 is a bolt, and the locking hole 9 is a threaded hole that is threadedly matched with the locking piece 8. After the locking piece 8 passes through the through hole 7, it is threadedly matched with the locking hole 9, thereby realizing the locking and fixing of the locking pressure rod 6 and the fixing seat 1. After the locking pressure rod 6 is threadedly connected to the fixing seat 1, one side of the locking pressure rod 6 conflicts with the tooth palm, ensuring that the tooth palm is firmly installed on the fixing seat 1.

[0037] refer to Figure 2 and Figure 3The bottom surface of the fixing seat 1 is protruding with a positioning piece 10, and the positioning piece 10 is a convex strip. The top surface of the base 2 is recessed to form a positioning groove 11 for positioning and cooperating with the positioning piece 10. When the fixing seat 1 is installed on the base 2, the positioning piece 10 on the fixing seat 1 is inserted into the positioning groove 11 on the base 2, thereby realizing the rapid positioning of the fixing seat 1 and the base 2, and ensuring the accuracy of the tooth palm welding position.
