[0002] Robotic arms for mechanical manufacturing are automated devices widely used in modern industrial manufacturing. Functioning similarly to a human arm, they possess multi-degree-of-freedom flexibility and can perform a variety of complex tasks. Robotic arms typically consist of multiple joints, enabling precise motion control during the manufacturing process, thereby improving production efficiency and quality.
[0003] Existing robotic arms for mechanical manufacturing mostly use cylinder grippers to hold and transfer workpieces. However, this design has certain limitations in mechanical manufacturing scenarios. Especially when facing workpieces of different shapes and sizes, cylinder grippers are usually limited by their mechanical structure, resulting in a small gripping range. They are difficult to adapt well to and grip the workpieces. At the same time, the gripping of cylinder grippers is not stable enough when facing tubular workpieces.
[0004] Considering the gripping stability of the robotic arm, a robotic arm for mechanical manufacturing is proposed to solve the above problems. Utility Model Content

[0009] The clamping assembly includes a base plate disposed on a positioning seat, and two adjusting seats are vertically mounted on the bottom of the base plate. The two adjusting seats are arranged in parallel and a gap is formed between them.
[0010] Two push plates are slidably disposed between the two adjustment seats, and the two push plates are respectively disposed on one side of one of the adjustment seats and are in contact with it;

[0012] As a further improvement of this utility model, a limiting plate is vertically arranged between the two adjusting seats; a ball bearing seat is mounted on the limiting plate, and a threaded screw is rotatably arranged inside the ball bearing seat; a reciprocating motor is installed on the side of the limiting plate, and the output end of the reciprocating motor passes through the limiting plate and extends to connect with one end of the threaded screw.

[0014] As a further improvement of this utility model, the moving block is vertically disposed between the two push plates and connected to the two push plates.
[0015] As a further improvement of this utility model, a mechanical component support seat is connected to the side of the base plate, and one side of the mechanical component support seat is protruding and a rubber plate is vertically installed.
[0016] As a further improvement of this utility model, the clamping plate has a slot on its side and a rubber pad is embedded therein. The rubber pad is fan-shaped and its sidewalls are arc-shaped.
[0017] In summary, the beneficial effects of the above-described technical solutions conceived by this utility model compared with the prior art include:
[0018] The mechanical manufacturing robotic arm of this utility model enables the machined workpiece to be stably clamped by the clamping assembly through the mutual movement and cooperation of multiple components set in the clamping assembly.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Example
[0026] Depend on Figure 1-3 A robotic arm for mechanical manufacturing is provided, comprising a robotic arm platform 1 and a robotic arm body 2.
[0027] The robotic arm body 2 is mounted on the robotic arm platform 1, and a positioning seat 3 is mounted on the robotic arm body 2.
[0028] The positioning base 3 has a clamping component 4 installed at its bottom;
[0029] The clamping assembly 4 includes a base plate 41 disposed on the positioning seat 3. Two adjusting seats 42 are vertically mounted on the bottom of the base plate 41. The two adjusting seats 42 are arranged in parallel and a gap is formed between them.
[0030] Two push plates 48 are slidably arranged between the two adjustment seats 42, and the two push plates 48 are respectively arranged on one side of one of the adjustment seats 42 and are in contact with it;
[0031] The ends of the two push plates 48 are connected to a clamping plate 49.
[0032] In this embodiment, the mutual movement and cooperation of multiple components disposed within the clamping assembly 4 enable the machined workpiece to be stably clamped by the clamping assembly 4. The clamping assembly 4 disposed on the robotic arm body 2 in this application can adapt to mechanical workpieces of different sizes without frequent changes of clamps. At the same time, the clamping range and position can be precisely controlled to meet the clamping requirements of mechanical workpieces of various specifications.
[0033] Furthermore, compared to the traditional cylinder gripper clamping method, the clamping component 4 of this application can achieve stable clamping of tubular workpieces by means of a sliding clamping plate 49 and a rubber pad 410 in conjunction with a rubber plate 440. This allows the robotic arm body 2 of this application to better adapt to and clamp tubular mechanical workpieces, and is especially suitable for high-precision, high-flexibility, and diversified modern mechanical manufacturing scenarios.
[0034] Specifically, refer to Figure 2-3 A limit plate 43 is vertically arranged between the two adjusting seats 42; a ball bearing seat 44 is mounted on the limit plate 43, and a threaded screw 45 is rotatably arranged inside the ball bearing seat 44; a reciprocating motor 420 is installed on the side of the limit plate 43, and the output end of the reciprocating motor 420 passes through the limit plate 43 and extends to connect with one end of the threaded screw 45.
[0035] In this embodiment, during use, the limiting plate 43 and the ball bearing seat 44 can be used to install the threaded screw 45, and the reciprocating motor 420 can be used to drive the threaded screw 45 to rotate.
[0036] Furthermore, by controlling the rotation direction of the output end of the reciprocating motor 420, the user can make the moving block 47 move in a reciprocating linear motion. During this process, the power connection method of the reciprocating motor 420 is the prior art, and the control circuit can be implemented by a person skilled in the art through simple programming. It is common knowledge in the art, and it is only used without modification. Therefore, the control method and circuit connection will not be described in detail.
[0037] Specifically, refer to Figure 2-3 The threaded screw 45 is externally engaged with a screw nut 46, and a movable block 47 is sleeved on the outside of the screw nut 46.
[0038] In this embodiment, when the threaded screw 45 rotates in both directions, it is limited by the contact of the adjusting seat 42 with the push plate 48, so that the screw nut 46 meshing with the outside of the threaded screw 45 can drive the moving block 47 to move in a reciprocating linear motion along the stroke range of the threaded screw 45.
[0039] Specifically, refer to Figure 2-3 The movable block 47 is vertically positioned between the two push plates 48 and connected to the two push plates 48.
[0040] In this embodiment, the connection between the moving block 47 and the two push plates 48 enables the moving block 47 to drive the push plates 48 to move synchronously when it is moving in a straight line.
[0041] Specifically, refer to Figure 2-3 The bottom plate 41 is connected to a mechanical component support seat 430 on its side. One side of the mechanical component support seat 430 is protruding and a rubber plate 440 is vertically installed.
[0042] In this embodiment, the mechanical support base 430 can provide initial support for the machined part. In a preferred embodiment, as shown in the example... Figure 2 As shown, the mechanical component support base 430 is also provided with a semi-circular bearing groove.
[0043] Specifically, refer to Figure 2-3 The clamping plate 49 has a slot on its side and a rubber pad 410 is embedded therein. The rubber pad 410 is fan-shaped and its side wall is arc-shaped.
[0044] In this embodiment, the rubber plate 440 and the rubber pad 410 are arranged opposite to each other. In use, the rubber pad 410 can work with the rubber plate 440 to clamp the machined parts. At the same time, both have soft texture, which can ensure that the pipe fittings of the construction project are not clamped during the clamping period.
[0045] The mechanical arm for mechanical manufacturing of this utility model:
[0046] Step 1: In actual use, when the user needs to clamp the workpiece, by driving the robotic arm body 2, the robotic arm body 2 can drive the positioning seat 3 to move. At this time, the positioning seat 3 can drive the clamping assembly 4 to move as a whole. Then, the user controls the clamping assembly 4 to move above the workpiece, and at this time, the user can drive the clamping assembly 4 to clamp the workpiece.
[0047] Step: When the user uses the clamping assembly 4 to clamp the machined part, the mechanical arm body 2 is driven and the machined part is placed on the arc groove formed at the bottom of the machined part support 430. Then, the user connects the power supply to the reciprocating motor 420. At this time, the reciprocating motor 420 drives the threaded screw 45 to rotate. When the threaded screw 45 rotates in both directions, it is limited by the contact of the adjusting seat 42 with the push plate 48, so that the screw nut 46 engaged with the outside of the threaded screw 45 can drive the moving block 47 to move in a reciprocating linear motion along the stroke range of the threaded screw 45.
[0048] Step 3: When the moving block 47 is in linear motion, the connection between the push plate 48 and the moving block 47 allows the clamping plate 49 at the end of the push plate 48 to drive the rubber pad 410 to move synchronously. At this time, the user drives the moving block 47 to move towards the rubber plate 440 until the machined part on the mechanical part support 430 can be tightly clamped by the rubber plate 440 and the rubber pad 410. At this time, by adjusting the clamping component 4, the machined part can be stably clamped.
[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
