Technical Field

[0001] This utility model belongs to the field of machining technology, and in particular relates to a dual-station switching machining fixture. Background Technology

[0002] Clamping plates are fundamental fixture components commonly used in machining, especially on machine tools such as milling machines, planers, drilling machines, and lathes. Their core function is to firmly clamp or press the workpiece onto the machine tool's worktable or fixture base, preventing movement or vibration during machining, thus ensuring machining accuracy and safety. After cutting and drilling, the blank workpiece requires deburring and grinding of its cut edges. Currently, manual hand-held grinding of blank workpieces suffers from poor safety, low grinding efficiency, and inconsistent grinding results. Summary of the Invention

The L-shaped plate is fixedly installed on the bottom surface of the left and right ends of the main platform. The vertical surface of the L-shaped plate is provided with through holes that cooperate with the infrared ranging sensor. The clamping mechanism consists of a vertical plate, a carrier, a pressure plate, a spring, a connecting rod, and a guide sleeve. The vertical plate and the carrier are fixedly installed on the main platform. The two guide sleeves are fixedly installed on the vertical plate. The two connecting rods are slidably installed inside the guide sleeves. The pressure plate is fixedly installed on the inner end of the connecting rod.

[0015] Figure 4 yes Figure 3 Enlarged structural diagram at point M. Detailed Implementation

[0016] The present invention will now be described in detail with reference to specific embodiments: like Figures 1 to 4 The dual-station switching machining fixture shown includes a base 1, a rotary cylinder 2, a main platform 3, an L-shaped bracket 4, an L-shaped plate 6, a clamping mechanism, and a control module. Two sets of clamping structures are set at the left and right ends of the main platform 3. The cylinder body of the rotary cylinder 2 and the L-shaped bracket 4 are fixedly installed on the base 1. The center position of the main platform 3 is fixedly installed on the turntable of the rotary cylinder 2. An infrared ranging sensor 42 is fixedly installed on the L-shaped bracket 4. The L-shaped plate 6 is fixedly installed on the bottom surface of the left and right ends of the main platform 3. The vertical surface of the L-shaped plate 6 is provided with through holes that cooperate with the infrared ranging sensor 42. The clamping mechanism consists of a vertical plate 51, a carrier 7, a pressure plate 8, a spring 9, a connecting rod 91, and a guide sleeve 92. The vertical plate 51 and carrier 7 are fixedly mounted on the main platform 3. Two guide sleeves 92 are fixedly mounted on the vertical plate 51. Two connecting rods 91 are slidably mounted within the guide sleeves 92. The pressure plate 8 is fixedly mounted on the inner end of the connecting rod 91. The spring 9 is sleeved on the connecting rod 91, with its two ends acting on the guide sleeve 92 and the pressure plate 8, respectively. The rotary cylinder 2 is connected to the air pressure station via pipelines and a solenoid valve. The solenoid valve and the infrared ranging sensor 42 are connected to the control module via circuits.

[0017] The main platform 3 has two fixed loading platforms 5 at its left and right ends. Two sets of clamping structures are respectively set on the left and right loading platforms 5. When changing workpieces of different sizes and specifications, the clamping structures and loading platforms 5 can be removed together, which has the advantage of convenient replacement.

[0018] The outer end of the connecting rod 91 is fixedly fitted with an anti-disengagement stop ring 93 to prevent the connecting rod 91 from detaching from the vertical plate 51 under the action of the spring force of the spring 9.

[0019] The positioning groove inlet end of the carrier 7 has an angled structure 71, which facilitates the placement of the workpiece 10 blank into the positioning groove of the carrier 7.

[0020] A handle 81 is fixedly installed on the pressure plate 8, which makes it convenient for the operator to overcome the elastic force of the spring 9 and pull the pressure plate 8 outward to put the workpiece 10 blank into the positioning groove of the carrier 7.

[0021] The L-shaped bracket 4 is fixedly mounted with a support wheel 41. The bottom surface of the main platform 3 is placed on the support wheel 41. The support wheel 41 can support the main platform 3, prevent the right side of the machining end from being subjected to downward force, reduce the load on the turntable of the rotary cylinder 2, and extend its service life.

[0022] The workpiece 10 blank is placed in the positioning groove of the carrier 7. Under the action of the spring 9, the pressure plate 8 presses and positions the workpiece 10 blank in the positioning groove of the carrier 7. To increase the pressing force of the pressure plate 8 on the workpiece 10 blank, a clamping bolt 82 can be set on the vertical plate 51. Tightening the clamping bolt 82 will press the pressure plate 8 firmly, preventing the workpiece 10 blank from shifting during the grinding process and further improving safety. The clamping mechanism on the left serves as the loading and unloading station for the workpiece 10 blank; the clamping mechanism on the right serves as the grinding station, which works with the automated grinding equipment to perform grinding operations and process the finished clamping plate. The rotary cylinder 2 drives the main carrier 3 and the clamping mechanism to rotate 180° to switch the station. When the infrared light from the infrared ranging sensor 42 passes through the through hole on the vertical surface of the L-shaped plate 6, the station switch is completed. The infrared ranging sensor 42 sends a signal to the control module, and the control module controls the infrared ranging sensor 42 to stop operating.
