[0001] The utility model belongs to the technical field of screw thread rolling equipment, and more specifically, particularly relates to a platform type thread rolling force testing device. Background Art

[0002] In the production process of screws, thread rolling is an important link. Through the thread rolling process, the semi-finished screws can be processed into screws with specific threads. The fully automatic thread rolling machine is a commonly used screw thread rolling equipment. The existing fully automatic thread rolling machine is generally composed of a main machine, a thread rolling slider, a driving mechanism that drives the thread rolling slider to move left and right, and a feeding system.

[0003] Based on the above, in the process of thread rolling of screws of different types, the specific force required to drive the thread rolling slider to roll the screws is mostly determined based on existing data.

At this time, it is easy to make errors when thread rolling the screws based on the original data, resulting in problems with the finished screw products. The existing thread rolling machines cannot display the specific force used to drive the thread rolling slider during the screw thread rolling process, resulting in no way to improve the thrust of the thread rolling slider even if one wants to.

[0049] Embodiment 1:

[0056] A guard plate 401, wherein two guard plates 401 are provided, and the two guard plates 401 are respectively fixedly connected to the front and rear surfaces of the conveying member 4;

[0057] A receiving piece 5, which is arranged on the left side of the thread rolling machine body 1, and the inside of the receiving piece 5 is divided into five areas;

[0058] A pressure testing assembly is arranged on the top of the thread rolling machine body 1 .

[0059] The stress test components include:

[0060] The driving cylinder 2 is fixedly connected to the left side of the thread rolling machine body 1, and the piston rod end of the driving cylinder 2 is fixedly connected to the right side of the thread rolling slider 202;

[0061] The pressure gauge 201 is arranged in front of the driving cylinder 2 .

[0062] The specific usage and function of this embodiment are as follows:

[0063] When the screw thread rolling effect becomes worse, the traditional thread rolling machine uses a crank slider mechanism to push the thread rolling slider 202 to move left and right when rolling the screw, and the thrust in this process cannot be clearly seen. The movement of the piston rod of the driving cylinder 2 is used to replace the crank slider mechanism of the traditional thread rolling machine to push the thread rolling slider 202 to move left and right. The driving cylinder 2 uses different forces to push the piston rod to move left to roll the screw. The pressure gauge 201 can display the thrust released by the driving cylinder 2, so that the size of the force required for rolling the screw of this model can be determined according to the forming quality of the screw after thread rolling. After multiple tests, the most suitable thrust is determined to provide theoretical data support for the subsequent thread rolling production of this model of screws.

[0064] Embodiment 2:

[0065] Based on the first embodiment, as shown in the attached Figure 1 To Attachment Figure 6 As shown, a material collection assembly is also included, and the material collection assembly is arranged on the left side of the thread rolling machine body 1.

[0066] The aggregate components include:

[0067] A first sliding block 6, the first sliding block 6 is slidably connected inside the rear baffle 101;

[0068] The transmission rack 601 is fixedly connected to the left side of the first sliding block 6. The function brought about is that after the thread rolling slider 202 completes the thread rolling of the screw, it will move the first sliding block 6 to the left, and the first sliding block 6 drives the transmission rack 601 to move to the left at the same time.

[0069] The aggregate components also include:

[0070] A connecting member 7, the connecting member 7 is fixedly connected to the left side of the thread rolling machine body 1;

[0071] A first transmission shaft 8, the first transmission shaft 8 is rotatably connected inside the fixing member 3 and the connecting member 7;

[0072] Transmission gear 801 is coaxially fixedly connected to the top of the first transmission shaft 8, and the transmission gear 801 is meshed with the transmission rack 601. The effect is that the transmission rack 601 moves to the left and drives the first transmission shaft 8 to rotate through the gear rack transmission mechanism formed by the meshing with the transmission gear 801.

[0073] The aggregate components also include:

[0074] A transmission pawl 802, the transmission pawl 802 is coaxially fixedly connected to the bottom of the first transmission shaft 8;

[0075] A connecting shaft 9, the connecting shaft 9 is rotatably connected inside the fixing member 3;

[0076] A driving bevel gear 901, which is coaxially fixedly connected to the top of the connecting shaft 9;

[0077] The transmission ratchet 902 is coaxially fixedly connected to the active bevel gear 901, and the transmission ratchet 902 is engaged with the transmission pawl 802. The effect brought about is that the rotation of the first transmission shaft 8 will drive the connecting shaft 9 and the active bevel gear 901 to rotate unidirectionally through the ratchet and pawl transmission mechanism jointly formed by the engagement of the transmission ratchet 902 and the transmission pawl 802.

[0078] The aggregate components also include:

[0079] A reciprocating screw 10, the reciprocating screw 10 is rotatably connected inside the fixing member 3;

[0080] A driven bevel gear 1001, which is coaxially fixedly connected to the rear end of the reciprocating screw 10, and is meshed with the driving bevel gear 901;

[0081] The second sliding block 11 is slidably connected to the bottom of the fixed member 3. The second sliding block 11 is threadedly connected to the reciprocating screw 10. The left end of the second sliding block 11 is fixedly connected to the rear end of the right side of the material receiving member 5. The effect is that the rotation of the active bevel gear 901 will drive the reciprocating screw 10 to rotate through the bevel gear transmission mechanism formed by the meshing with the driven bevel gear 1001. The reciprocating screw 10 drives the material receiving member 5 to move forward and backward through the threaded transmission mechanism formed by the second sliding block 11.

[0082] The aggregate components also include:

[0083] The return spring 602, the left end of the return spring 602 is fixedly connected to the right side of the first sliding block 6, and the right end of the return spring 602 is fixedly connected to the inside of the rear baffle 101. The effect is that when the piston rod of the driving cylinder 2 moves to the right to drive the thread rolling slider 202 to reset, under the action of the return spring 602, the first sliding block 6 and the transmission rack 601 move to the right and reset.

[0084] The specific usage and function of this embodiment are as follows:

[0085] After the thread rolling slider 202 has finished thread rolling the screw, the screw will roll into an area separated by the material receiving piece 5 through the conveying piece 4 and the fixing piece 3. When the thread rolling slider 202 moves to contact with the first sliding block 6, the thread rolling slider 202 drives the first sliding block 6 to move left, and the first sliding block 6 drives the transmission rack 601 to move left at the same time. The transmission rack 601 moves leftward and drives the first transmission shaft 8 to rotate through the gear rack transmission mechanism formed by the meshing with the transmission gear 801. The rotation of the first transmission shaft 8 will drive the connecting shaft 9 and the active bevel gear 901 to rotate unidirectionally through the ratchet and pawl transmission mechanism formed by the meshing of the transmission ratchet 902 and the transmission pawl 802. The rotation of the active bevel gear 901 will drive the reciprocating screw 10 to rotate through the bevel gear transmission mechanism formed by the meshing with the driven bevel gear 1001. The reciprocating screw 10 drives the material receiving piece 5 to move backward through the thread transmission mechanism formed by the second sliding block 11, and then drives the piston rod of the oil cylinder 2 to move right. When the thread rolling slider 202 is driven to reset, under the action of the reset spring 602, the first sliding block 6 and the transmission rack 601 move rightward to reset, and under the action of the ratchet and pawl transmission mechanism composed of the meshing of the transmission ratchet 902 and the transmission pawl 802, the material receiving piece 5 will not follow the movement, thereby completing the unidirectional movement of the material receiving piece 5, so that each screw completed by thread rolling using different thrusts will fall into the five areas separated in the material receiving piece 5 respectively, and no longer need to be collected individually, which greatly speeds up the efficiency of the screw thread rolling force test. After all the five areas in the material receiving piece 5 are collected, the second sliding block 11 has slid to the rear end of the reciprocating screw 10, and the five screws are taken out respectively to determine the thread rolling effect; when the driving cylinder 2 is started again, when the reciprocating screw 10 rotates again, since the second sliding block 11 has slid to the rear end of the reciprocating screw 10 at this time, the second sliding block 11 will drive the material receiving piece 5 to move forward, so that the five thread rolling screws can be collected again.
