Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] like Figures 1 to 4 As shown, the present invention provides an electric tool assembly type mechanical device,

[0045] The utility model comprises a frame, an upper push rod 2 and a lower push rod 3 are respectively arranged on the inner longitudinal central axis of the frame 1, an upper rolling block 4 is arranged on the telescopic end of the upper push rod 2 and can control the upper rolling block 4 to move downward toward the direction of the lower push rod 3, a lower rolling block 5 is arranged on the telescopic end of the lower push rod 3 and can control the lower rolling block 5 to move upward toward the direction of the upper push rod 2, and the upper rolling block 4 and the lower rolling block 5 can jointly drive and roll the outer side of the electric tool assembly head;

A part of the assembly head belt 7 can bypass the upper rolling block 4 and form a U-shaped structure for the assembly head of the power tool to pass through directly below the upper rolling block 4. Tightening mechanisms 8 that can tighten the assembly head belt 7 are provided on both sides of the upper rolling block 4. The transmission mechanism 6 automatically tightens or loosens the assembly head of the power tool by driving the tightened assembly head belt 7.

[0047] In actual use, it can be coordinated with a horizontally set track, on which are two slides that can slide along the track, and on the two slides are respectively provided a clamp for clamping the power tool and a tool seat for placing various tool heads. A frame 1 is provided between the two slides in the middle of the track. One slide can move toward the frame 1 together with the power tool fixed on the clamp, and the other slide can move toward the frame 1 together with the tool seat.

[0048] On the production line of the power tool base, sampling inspection is generally required to test the matching of the tool head and the power tool base. For this set of power tools, it is necessary to continuously replace multiple tool heads for matching inspection. During the matching inspection process, the power tool base and the tool head installation slots need to be kept in relative position for correct insertion, and then the power tool base or tool head is rotated at a fixed angle so that the power tool base and tool head are rotated into place, and the electric test is performed after the positioning is completed.

[0049] Since existing robotic arms and other devices still exist in actual operations, it is difficult to accurately connect the power tool base and the tool head, and it is difficult to automatically tighten or loosen the assembly head of the power tool. Therefore, matching tests are generally performed manually, and the degree of automation is low.

[0050] By controlling the upper rolling block and the lower rolling block relative to the outer side of the assembly head of the electric tool, the assembly head of the electric tool can always be aligned with the direction of the tool seat and is not prone to tilting. Therefore, the CNC tool seat can be used to automatically insert or remove the tool in the electric tool assembly head at a specified position.

[0051] By using the belt to form a U-shape, the assembly head of the power tool can be automatically extended or retracted, and then the belt is controlled to fully fit the outside of the assembly head of the power tool. When the belt is transmitted, the assembly head of the power tool can be automatically tightened or loosened through the belt, thereby improving the degree of automation of the device.

[0052] A second arc groove 51 is provided on the front and rear center axis of the top of the lower rolling block 5, and the second arc groove 51 matches the outer side of the electric tool assembly head. A second belt groove 52 is provided on the left and right center axes of the top of the lower rolling block 5, and a plurality of second support rollers 53 for pressing the outer side of the electric tool assembly head are rotatably connected to the inner side of the second belt groove 52.

[0053] Among them, a plurality of second support rollers 53 are evenly distributed on the arc-shaped portion of the second belt groove 52 located at the second arc groove 51, and the lower rolling block 5 is raised to enable the plurality of second support rollers 53 to roll evenly on the outside of the U-shaped assembly head belt 7;

[0054] The width of the second belt groove 52 is greater than the width of the assembly head belt 7 .

[0055] A first arc groove 41 extending from front to back is provided on the front and rear center axis of the bottom end of the upper rolling block 4, and the first arc groove 41 coincides with the outer side of the electric tool assembly head, and a first belt groove 42 extending from left to right is provided on the left and right center axes of the bottom end of the upper rolling block 4, and four first support rollers 43 for pressing the outer side of the electric tool assembly head are rotatably connected to the inner side of the first belt groove 42, and two roller frame grooves 44 extending from left to right are provided on the inner side of the first belt groove 42;

[0056] Among them, the four first support rollers 43 are equidistantly distributed on the arc portion of the first belt groove 42 located at the first arc groove 41, and the upper rolling block 4 descends to enable the two first support rollers 43 located in the middle to roll on the outside of the electric tool assembly head;

[0057] The two first support rollers 43 in the middle are of the same height, and the two first support rollers 43 on the outside are of the same height. The two first support rollers 43 on the outside are used to roll the inner side of the assembly head belt 7;

[0058] The two roller frame grooves 44 are respectively located in the middle of both sides of the first belt groove 42;

[0059] The width of the first belt groove 42 is greater than the width of the assembly head belt 7 .

[0060] Slide bars are arranged at the four corners of the upper rolling block 4 and the lower rolling block 5 and are fixedly connected to the inner side of the frame 1 . The upper rolling block 4 and the lower rolling block 5 can be vertically lifted and lowered in the frame 1 through the slide bars at the four corners.

[0061] The transmission mechanism 6 includes a fixed box 61 fixed to the top of the frame 1, two driven rollers 62 for rolling the outer side of the assembly head belt 7 are rotatably connected in the fixed box 61, and a driving roller 63 for rolling the inner side of the assembly head belt 7 is rotatably connected between the two driven rollers 62, and a stepping motor 64 for driving the driving roller 63 to rotate is arranged on the outer side of the fixed box 61;

[0062] The outer side of the driving roller 63 and the outer sides of the two driven rollers 62 form two rolling force points for rolling the assembly head belt 7;

[0063] The inner side of the assembly head belt 7 matches the structure of the outer side of the electric tool assembly head, and the transmission pressure roller 63 matches the inner side structure of the assembly head belt 7 .

[0064] The tightening mechanism 8 includes an internal supporting mechanism 81 arranged at the top of the upper rolling block 4, and two external rolling mechanisms 82 respectively arranged on the left and right sides of the lower push rod 3. The internal supporting mechanism 81 is used to elastically support the inner side of the assembly head belt 7, and the external rolling mechanism 82 is used to elastically press the outer side of the assembly head belt 7.

[0065] The internal supporting mechanism 81 includes a fixing frame 811 fixed at the middle position of the top of the upper rolling block 4, and connecting rods 812 are rotatably connected on both sides of the fixing frame 811. Dislocation guide rods 813 are provided on the opposite surfaces of the two connecting rods 812, and springs 814 are sleeved on the outer sides of the two dislocation guide rods 813. The springs 814 elastically support the two connecting rods 812 on the two dislocation guide rods 813, so that the two connecting rods 812 form two elastic support points on the inner side of the assembly head belt 7. The U-shaped structure at the bottom end of the upper rolling block 4 can be enlarged through the two elastic support points on the inner side of the assembly head belt 7 to allow the assembly head of the power tool to pass through;

[0066] Wherein, the fixing frame 811 is located on the upper rolling block 4 outside the telescopic end of the upper push rod 2;

[0067] The end of the connecting rod 812 is rotatably connected to a first driven roller 815 for rolling the inner side of the assembly head belt 7 .

[0068] The external rolling mechanism 82 includes an external fixing frame 821 fixed on one side of the upper rolling block 4, and a roller sliding frame 822 is slidably connected to the external fixing frame 821. A cylinder 823 for controlling the roller sliding frame 822 to slide against the upper rolling block 4 is arranged on the outer side of the external fixing frame 821. The end of the roller sliding frame 822 close to the upper rolling block 4 is rotatably connected to a second driven roller 824 for rolling the outer side of the assembly head belt 7.

[0069] The roller slide frame 822 moves toward the upper rolling block 4 and can roll the assembly head belt 7 laterally through the second driven roller 824, so that the U-shaped structure size formed by the assembly head belt 7 at the bottom end of the upper rolling block 4 continues to shrink to fit the outer side of the assembly head of the power tool.

[0070] When testing the electric tool, the electric tool needs to be fixed on a fixture of a slide first, and the slide is controlled to move toward the frame 1 so that the electric tool can move toward the frame 1 .

[0071] After the assembly head of the electric tool passes through the assembly head belt 7, the telescopic end of the wire-controlled lower push rod 3 is extended quantitatively, and the lower rolling block 5 is raised quantitatively until the multiple second support rollers 53 in the second arc groove 51 at the top of the lower rolling block 5 are attached to the outer side of the U-shaped assembly head belt 7 to support the outer side of the assembly head of the electric tool, so that when the assembly head of the electric tool is subjected to pressure from above, the pressure can be transmitted to the lower rolling block 5 without tilting.

[0072] After the lower rolling block 5 has finished rising, the telescopic end of the upper push rod 2 is controlled to extend together with the upper rolling block 4 to descend until the two first support rollers in the middle of the first arc groove 41 at the bottom end of the upper rolling block 4 are pressed against the outside of the assembly head of the power tool. At this time, the two first support rollers 43 of the upper rolling block 4 will press the assembly head of the power tool, the U-shaped assembly head belt and the multiple second support rollers of the lower rolling block 5. At this time, the position of the assembly head of the power tool is fixed, which is directly opposite to the upper tool position of the tool seat on the other slide. By controlling the slide to move toward the direction of the frame 1, the tool in the upper position on the tool seat is inserted into the assembly head of the power tool.

[0073] After the tool is inserted into the assembly head of the power tool, the telescopic ends of the cylinders of the two external rolling mechanisms 82 are controlled to begin to extend, and move together with the roller slide frame 822 on the external fixed frame 821 toward the first belt groove 42 of the upper rolling block 4, so that the second driven roller 824 at the end of the roller slide frame 822 presses the assembly head belt 7 at the corresponding position into the first belt groove 42 during the movement.

[0074] The two second driven rollers 824 press the two sides of the U-shaped assembly head belt 7 relatively into the first belt groove 42, so that the size of the U-shaped part of the assembly head belt 7 will continue to shrink until the assembly head belt 7 is fully fitted to the outside of the assembly head of the power tool.

[0075] Afterwards, the stepper motor 64 that controls the transmission mechanism 6 starts to run, and rotates together with the transmission pressure roller 63 in the fixed box 61. Since the assembly head belt 7 in the fixed box 61 is formed with two driven pressure rollers 62 and the transmission pressure roller 63 to form two rolling points for pressing the assembly head belt 7, the assembly head belt 7 can be transmitted when the transmission pressure roller 63 rotates. When the assembly head belt 7 is transmitted, it can rotate in the corresponding direction together with the assembly head of the electric tool that is fully fitted. Then, the transmission direction of the stepper motor 64 can be controlled to realize automatic tightening or loosening of the assembly head of the electric tool.
