Description

Technical Field

[0001] The present invention relates to the technical field of automatic pin insertion machines, and in particular to a T-type pin positioning and pressing device and a pressing method. Background Art

[0002] Automotive actuators are key components of modern automobiles, and the pin insertion process plays a pivotal role in their manufacturing process. The challenges faced in processing T-type PIN pins in today's automotive actuator manufacturing mainly include the slow speed of pin insertion. In the semi-automatic pin insertion process, the insertion speed of T-type PIN pins is limited, which becomes a key factor affecting production efficiency. In addition, workers need to frequently manually operate the jig to insert the T-type PIN pins, which not only increases the labor intensity of the operators, but also may affect production efficiency. At the same time, frequent manual operations may lead to human errors, affect the insertion accuracy of the T-type PIN pins, and thus affect the performance of automotive actuators.

[0003] In response to these challenges, the present invention proposes an innovative process method, which aims to improve the efficiency of pin insertion through highly automated technical means, achieve accurate and rapid positioning of T-type PIN pins, and ensure the accuracy and stability of the pin insertion operation. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a T-type pin positioning and pressing device and a pressing method in view of the deficiencies of the above-mentioned prior art. The T-type pin positioning and pressing device and the pressing method can accurately and automatically press-fit a plurality of T-type pins into the T-type pin holes of the T-type housing of the automobile actuator synchronously, and ensure that each T-type pin can be correctly and consistently inserted into the predetermined position, and the pin qualification rate is high.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A T-type pin positioning and pressing device comprises a T-type shell pressing plate, a T-type positioning tool, a T-type pressing and lifting assembly and a horizontal pressing assembly.

[0007] The T-shaped pin can be plugged into the T-shaped pin hole of the T-shaped housing. The T-shaped housing is located on the housing transmission line. The housing transmission line has a T-shaped pin positioning and pressing station.

[0008] The T-type shell clamping plate is arranged directly above the T-type pin positioning and pressing station, and can be driven by the T-type pressing and lifting assembly to achieve height lifting and lowering, and clamp and position the top of the T-type shell located on the T-type pin positioning and pressing station.

[0009] A T-shaped positioning opening groove is arranged on the pressing plate of the T-shaped shell, and an opening is arranged toward the direction of the T-shaped pin hole of the T-shaped shell.

[0010] The T-shaped positioning tooling comprises a T-shaped positioning plate, a T-shaped supporting slider, a T-shaped supporting slider driving assembly and a horizontal push head.

[0011] The T-shaped positioning plate is arranged at the bottom of the T-shaped shell pressing plate just below the T-shaped positioning opening groove, and can extend into the inner cavity of the T-shaped shell.

[0012] The T-shaped positioning plate is provided with T-shaped positioning grooves which are equal in number to and correspond to the T-shaped pin holes, and each T-shaped positioning groove can position and place a T-shaped pin.

[0013] The T-shaped support slider is arranged at the front end of the T-shaped positioning plate facing the T-shaped pin hole, and can slide left and right along a direction perpendicular to the T-shaped positioning groove under the drive of the T-shaped support slider driving assembly.

[0014] The T-shaped support sliding block is provided with T-shaped through slots, the number of which is equal to the number of the T-shaped positioning slots and the tops of which are open.

[0015] The horizontal push head is arranged on the top of the T-shaped positioning plate and can contact with the T-shaped pins in all the T-shaped positioning grooves.

[0016] The horizontal clamping assembly is used to drive the horizontal movement of the horizontal push head.

[0017] Each T-shaped pin includes a horizontal portion and a vertical portion, wherein the horizontal portion is a horizontal plug-in portion that matches the T-shaped pin hole; and the two ends of the vertical portion are a T-shaped convex portion and an electrical interface portion respectively.

[0018] Each T-shaped positioning groove includes a convex portion guiding groove, which can accommodate the T-shaped convex portion and guide the horizontal movement of the T-shaped convex portion.

[0019] The T-shaped support slider can support the front end of the plug-in part so that the plug-in part can maintain a horizontal state during the horizontal movement.

[0020] Each T-shaped positioning groove also includes an L-shaped pin guide placement groove located at the top of the convex guide groove, which is used for guiding when placing the L-shaped pin.

[0021] A supporting sliding groove is arranged at the front end of the T-shaped positioning plate facing the T-shaped pin hole, and the supporting sliding groove is perpendicular to the T-shaped positioning groove.

[0022] The T-shaped supporting sliding block is arranged in the supporting sliding groove.

[0023] The T-shaped support slider driving assembly includes a positioning pin and a driving arm; the bottom end of the positioning pin is connected to one end of the T-shaped support slider, and the top end of the positioning pin is connected to the driving arm; the driving arm has a T-shaped pin positioning blocking surface.

[0024] A horizontal guide push rod is connected to the middle and upper part of the horizontal push head, and horizontal return springs are arranged on both sides of the horizontal guide push rod. The horizontal return springs can make the horizontal push head be located at the setting position on the top of the T-shaped positioning plate.

[0025] A T-type pin positioning and pressing method comprises the following steps.

[0026] Step 1. Press the T-shaped shell: the T-shaped shell pressing plate is driven by the T-shaped press-fitting lifting assembly to descend in height, thereby pressing and positioning the top of the T-shaped shell located on the T-shaped pin positioning press-fitting station; at the same time, the T-shaped positioning plate carries the T-shaped supporting slider and synchronously extends into the inner cavity of the T-shaped shell; wherein, the T-shaped supporting slider faces the T-shaped pin hole of the T-shaped shell and is at the same height as the bottom surface of the T-shaped pin hole.

[0027] Step 2, place the T-pin: in each T-shaped positioning slot of the T-shaped positioning plate, a T-shaped pin is placed using a pin press-fit transfer assembly; wherein, the T-shaped protrusion of the T-shaped pin extends into the T-shaped positioning slot and is positioned and contacted with the bottom surface of the T-shaped positioning slot, and the front end of the plug-in part of the T-shaped pin is placed on the T-shaped supporting slider, kept in a horizontal state, and the tip points to the T-shaped pin hole.

[0028] Step 3: One-time press-fitting of T-pins: The horizontal pressing assembly drives the horizontal push head to move horizontally and contact the vertical parts of all T-pins in all T-positioning grooves; the horizontal push head continues to move forward horizontally, and the tip of the plug-in part of each T-pin enters the corresponding T-pin hole to the set one-time press-fitting depth.

[0029] Step 4, T-shaped support slider slides: driven by the T-shaped support slider driving assembly, the T-shaped support slider slides in a direction perpendicular to the T-shaped positioning slot, so that the T-shaped through slots of all T-shaped support sliders are connected with the corresponding T-shaped positioning slots one by one.

[0030] Step 5, secondary press-fitting of T-pins: The horizontal clamping assembly drives the horizontal push head to continue to move horizontally forward until the vertical portion of each T-pin passes through the T-slot of the corresponding T-support slider and has no contact with the T-positioning plate and the T-support slider; at this time, the plug-in portion of each T-pin is press-fitted into the corresponding T-pin hole.

[0031] Step 6: Positioning and resetting: The horizontal clamping assembly and the horizontal push head are reset, and the T-shaped support slider is reset to form a blockage for the front end of each T-shaped positioning slot.

[0032] Step 7, T-type shell circulation: The T-type shell clamping plate is driven by the T-type press-fitting lifting assembly to rise in height and reset, thereby contacting and pressing the T-type shell. The press-fitted T-type shell is transferred to the next process; repeat steps 1 to 7 to position and press-fit the T-type pin in the next T-type shell to be press-fitted.

[0033] In step 2, an L-shaped pin guide placement groove with a trumpet-shaped opening is provided on the top of each T-shaped positioning groove to facilitate the positioning and placement of the T-shaped pin.

[0034] In step 4, the T-shaped support slider driving assembly includes a driving arm, which has a T-shaped pin positioning blocking surface. Before the T-shaped support slider driving assembly drives the T-shaped support slider to slide, the T-shaped pin positioning blocking surface can contact the horizontal push head to limit the one-time pressing position of the T-shaped pin in step 3; when the T-shaped support slider driving assembly drives the T-shaped support slider to slide, the T-shaped pin positioning blocking surface will release the positioning blockage with the horizontal push head.

[0035] In step 6, the horizontal clamping assembly and the horizontal push head are designed to be separated. After the horizontal clamping assembly is reset, the horizontal push head resets itself to the starting position away from the T-shaped pin hole under the action of its own spring force.

[0036] The present invention has the following beneficial effects: the T-shaped shell clamping plate in the present invention can clamp the T-shaped shell to be press-fitted with the pins, which is convenient for the subsequent press-fitting of the T-shaped pins; the T-shaped positioning tool in the present invention can position the T-shaped pins, so that the plug-in part of each T-shaped pin is kept in a horizontal state, and the tip points to the T-shaped pin hole, and the front end of the plug-in part of each T-shaped pin is placed on the T-shaped support slider to prevent the T-shaped pin from deforming when entering the corresponding T-shaped pin hole, thereby ensuring the assembly accuracy and success rate. In addition, the horizontal clamping assembly can make all the T-shaped pins in each T-shaped shell press-fitted synchronously at one time, so that the press-fitting consistency is high and the qualified rate is high.

[0076] A T-type pin positioning and pressing method comprises the following steps.

[0077] Step 1. Press the T-shaped shell: the T-shaped shell pressing plate is driven by the T-shaped press-fitting lifting assembly to descend in height, thereby pressing and positioning the top of the T-shaped shell located on the T-shaped pin positioning press-fitting station; at the same time, the T-shaped positioning plate carries the T-shaped supporting slider and synchronously extends into the inner cavity of the T-shaped shell; wherein, the T-shaped supporting slider faces the T-shaped pin hole of the T-shaped shell and is at the same height as the bottom surface of the T-shaped pin hole.

[0078] Step 2, place the T-pin: in each T-shaped positioning slot of the T-shaped positioning plate, a T-shaped pin is placed using a pin press-fit transfer assembly; wherein, the T-shaped protrusion of the T-shaped pin extends into the T-shaped positioning slot and is positioned and contacted with the bottom surface of the T-shaped positioning slot, and the front end of the plug-in part of the T-shaped pin is placed on the T-shaped supporting slider, kept in a horizontal state, and the tip points to the T-shaped pin hole.

[0079] Step 3: One-time press-fitting of T-pins: The horizontal pressing assembly drives the horizontal push head to move horizontally and contact the vertical parts of all T-pins in all T-positioning grooves; the horizontal push head continues to move forward horizontally, and the tip of the plug-in part of each T-pin enters the corresponding T-pin hole to the set one-time press-fitting depth.

[0080] Furthermore, before the T-shaped support slider driving assembly drives the T-shaped support slider to slide, the T-shaped pin positioning blocking surface can contact the horizontal push head to limit the one-time press-fit position of the T-shaped pin in step 3.

[0081] Step 4: T-type support slider slides

[0082] The T-shaped support slider is driven by the T-shaped support slider driving assembly to slide along a direction perpendicular to the T-shaped positioning slot, so that the T-shaped through slots of all T-shaped support sliders are connected to the corresponding T-shaped positioning slots one by one.

[0083] When the T-shaped support slider driving assembly drives the T-shaped support slider to slide, the T-shaped pin positioning blocking surface will release the positioning blocking with the horizontal push head.

[0084] Step 5, secondary press-fitting of T-pins: The horizontal clamping assembly drives the horizontal push head to continue to move horizontally forward until the vertical portion of each T-pin passes through the T-slot of the corresponding T-support slider and has no contact with the T-positioning plate and the T-support slider; at this time, the plug-in portion of each T-pin is press-fitted into the corresponding T-pin hole.

[0085] Step 6, positioning and resetting: the horizontal clamping assembly and the horizontal push head are reset, and the T-shaped support slider is reset to form a block for the front end of each T-shaped positioning slot. Furthermore, the horizontal clamping assembly and the horizontal push head are designed to be separated. After the horizontal clamping assembly is reset, the horizontal push head automatically resets to the starting position away from the T-shaped pin hole under the action of its own spring force.

[0086] Step 7, T-type shell circulation: The T-type shell clamping plate is driven by the T-type press-fitting lifting assembly to rise in height and reset, thereby contacting and pressing the T-type shell. The press-fitted T-type shell is transferred to the next process; repeat steps 1 to 7 to position and press-fit the T-type pin in the next T-type shell to be press-fitted.
