Description

Technical Field

[0001] This utility model relates to the technical field of positioning mechanisms for processing metal casting blanks, and specifically discloses a positioning mechanism for processing blanks. Background Technology

[0002] Precise positioning before blank processing is crucial for ensuring processing quality and efficiency. Currently, common blank processing positioning machines on the market have several limitations. Firstly, traditional positioning machines have relatively simple clamping structures, mostly featuring only one fixed clamping method, such as a planar clamping section or a V-groove clamping structure. This limits their applicability to blanks of specific shapes, failing to effectively clamp and position irregularly shaped or diverse blanks, significantly restricting the equipment's versatility and applicability. Secondly, most positioning machines lack real-time monitoring and effective control of clamping force. When clamping blanks, excessive clamping force can damage the blank surface, while insufficient clamping force can cause the blank to slip during processing, affecting processing quality and safety. Furthermore, existing positioning machines are relatively complex to operate, with cumbersome adjustment processes, increasing operational difficulty and reducing work efficiency.

[0003] Therefore, there is an urgent need for a positioning machine for blank processing that can solve the above problems, achieve multi-functional clamping, precise positioning and control, convenient operation and reliable structure. Utility Model Content

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0029] Please see Figure 1-5 A positioning mechanism for blank processing includes an operating table 1, a rotatable disc-shaped storage seat 2 on the top of the operating table 1, an engagement cavity 3 inside the operating table 1, and a transmission component for driving the storage seat 2 to rotate inside the engagement cavity 3.

[0030] Two sets of lifting adjustment components 4 are symmetrically arranged on the surface of the storage seat 2, and each set of lifting adjustment components 4 is equipped with a positioning clamp 5 that can slide up and down;

[0031] The positioning clamp 5 includes a slide 6 connected to the lifting adjustment assembly 4, two electric telescopic rods 7 horizontally arranged on the side of the slide 6 away from the lifting adjustment assembly 4, mounting seats 8 respectively fixed to the output end of the electric telescopic rods 7, and a rotating clamp 10 hinged between the two mounting seats 8 via a horizontal rotating shaft 9.

[0032] The rotating clamping block 10 has a first clamping surface 11 and a second clamping surface 12 that are arranged opposite to each other. The first clamping surface 11 is provided with a V-groove, and the second clamping surface 12 is a planar clamping part.

[0033] One of the mounting bases 8 has a self-locking motor 13 on its outer side, and the output shaft of the self-locking motor 13 is coaxially connected to the rotating shaft 9 of the rotating clamp 10.

[0034] In this embodiment: The operator places the blank to be processed on the storage seat 2. According to the shape and size of the blank, the operator adjusts the height of the upper slide 6 of the lifting adjustment assembly 4 by rotating the adjusting screw 23 to place the positioning fixture 5 in a suitable position. Then, the electric telescopic rod 7 is activated to adjust the distance between the two mounting seats 8 to initially clamp the blank. According to the shape of the blank, the self-locking motor 13 drives the rotating clamping block 10 to rotate, switching to a suitable clamping surface to accurately clamp the blank. The pressure sensor 15 detects the clamping force in real time and transmits the signal to the control panel 16. If the clamping force exceeds the set threshold, the control panel 16 automatically adjusts the clamping force through the pressure threshold setting module linked with the self-locking motor 13. When it is necessary to adjust the processing angle of the blank, the operator rotates the manual adjustment wheel 20, which drives the worm gear 17 and the rotary table 19 to rotate through the worm gear 18, thereby driving the storage seat 2 and the blank to rotate to the required angle. After positioning is completed, the processing operation can be carried out.

[0035] By rotating the storage seat 2 and adjusting the positioning fixture 5, it can adapt to the processing needs of blanks of different shapes and sizes, improving the processing flexibility and versatility; the transmission component realizes the rotation of the storage seat 2, and the lifting adjustment component 4 realizes the height adjustment of the positioning fixture 5. The positioning fixture 5 realizes the precise clamping of the blank and the switching of different clamping surfaces through the electric telescopic rod 7 and the rotating clamping block 10, meeting diverse processing requirements.

[0036] As a technical optimization of this utility model, the surfaces of the V-groove and the flat clamping part are both covered with elastic pads 14 with anti-slip texture. A pressure sensor 15 is embedded inside the elastic pad 14, and the pressure sensor 15 is connected to a control panel 16 located on the operating table 1.

[0037] In this embodiment: the elastic pad 14 increases friction and cushioning to protect the surface of the blank; the pressure sensor 15 detects the clamping force in real time, and the control panel 16 is used to receive the signal from the pressure sensor 15 and display and control it, thereby enabling precise control of the clamping force, preventing damage to the blank, and ensuring stability and safety during the processing, thus improving the processing quality.

[0038] As a technical optimization of this utility model, the transmission assembly includes a worm gear 17 disposed in the meshing cavity 3, a worm gear 18 meshing with the worm gear 17, and a rotary table 19 coaxially connected to the worm gear 17. The end of the worm gear 18 passes through the side wall of the operating table 1 and is connected to a manual adjustment wheel 20. The upper end of the rotary table 19 is coaxially fixed to the storage seat 2.

[0039] In this embodiment, the rotation of the storage seat 2 can be conveniently controlled by manually adjusting the wheel 20. The operation is simple and reliable, and can meet the needs of different processing angles.

[0040] As a technical optimization of this utility model, the lifting adjustment component 4 includes a column 21 vertically fixed on the surface of the seat 2, a guide groove 22 opened on one side of the column 21 along the height direction, and an adjustment screw 23 that cooperates with the guide groove 22. The slide 6 is embedded in the guide groove 22 and forms a threaded connection with the adjustment screw 23.

[0041] In this embodiment, the height of the positioning fixture 5 can be flexibly adjusted by rotating the adjusting screw 23 according to the height of the blank, so as to ensure that the positioning fixture 5 can accurately clamp the blank and improve the applicability of the positioning machine.

[0042] As a technical optimization of this utility model, the worm gear module of the self-locking motor 13 is 1.5-2mm, the worm lead angle is 15-25°, and the motor power is 200-400W.

[0043] In this embodiment, the self-locking motor 13 can be guaranteed to have a good deceleration and torque increase effect, drive the rotating clamping block 10 to rotate stably, realize reliable switching of the clamping surface, and improve the working performance and reliability of the positioning machine.

[0044] As a technical optimization of this utility model, the rotating shaft 9 of the rotating clamp 10 is provided with self-lubricating bearings 24 at both ends, and a detachable dust cover 25 is provided outside the self-lubricating bearings 24.

[0045] In this embodiment: the self-lubricating bearing 24 reduces the friction and wear of the rotating shaft 9 and extends the service life of the rotating clamp 10; the dust cover 25 prevents dust from entering the bearing and ensures the normal operation of the bearing, thereby improving the stability and reliability of the rotating clamp 10 and reducing maintenance costs.

[0046] As a technical optimization of this utility model, the control panel 16 is provided with a pressure threshold setting module and a clamping surface angle display module, and the pressure threshold setting module and the self-locking motor 13 form a linkage control.

[0047] In this embodiment, the pressure threshold setting module and the clamping surface angle display module can realize automatic control of clamping force and real-time display of clamping surface angle, so that the operator can set the clamping force threshold according to the processing requirements to ensure processing safety; at the same time, the clamping surface angle display module can intuitively understand the working status of the positioning fixture 5, improving the accuracy and efficiency of operation.

[0048] Working principle and usage process of this utility model:

[0049] Place the blank to be processed in a suitable position on the base 2. Based on the blank's height, rotate the adjusting screw 23 to allow the slide 6 to slide up and down within the guide groove 22, adjusting the height of the positioning fixture 5 until it matches the blank's height. Activate the electric telescopic rod 7, adjusting the distance between the two mounting seats 8 through its telescopic movement, initially fixing the blank between the two rotating clamping blocks 10. Based on the blank's shape, activate the self-locking motor 13, driving the rotating clamping blocks 10 to rotate around the horizontal axis 9, switching to a suitable clamping surface for precise clamping of the blank. The pressure sensor 15 detects the clamping force in real time and transmits the signal to the control panel 16. If the clamping force does not meet the requirements... The control panel 16 automatically adjusts the clamping force. When the blank machining angle needs to be adjusted, the operator rotates the manual adjustment wheel 20, which drives the worm gear 18 to rotate the worm wheel 17 and the rotary table 19, thereby rotating the storage seat 2 and the blank to the required machining angle. The clamping surface angle display module displays the clamping surface angle of the rotating clamping block 10 in real time. After completing the above positioning and adjustment operations, the operator can process the blank. During the processing, the positioning machine continuously maintains stable clamping and positioning of the blank. After processing, first release the electric telescopic rod 7, take out the processed part, and then repeat the above operation process for the next positioning and processing according to the condition of the next blank.
